Benito Amilcare Andrea Mussolini KSMOM GCTE (29 July 1883, Predappio, Province of Forlì-Cesena - 28 April 1945) was an Italian politician who led the National Fascist Party and is credited with being one of the key figures in the creation of Fascism.

Mussolini became the 40th Prime Minister of Italy in 1922 and began using the title Il Duce by 1925. After 1936, his official title was "His Excellency Benito Mussolini, Head of Government, Duce of Fascism, and Founder of the Empire". Mussolini also created and held the supreme military rank of First Marshal of the Empire along with King Victor Emmanuel III of Italy, which gave him and the King joint supreme control over the military of Italy. Mussolini remained in power until he was replaced in 1943; for a short period after this until his death, he was the leader of the Italian Social Republic. Mussolini was among the founders of Italian Fascism, which included elements of nationalism, corporatism, national syndicalism, expansionism, social progress and anti-communism in combination with censorship of subversives and state propaganda. In the years following his creation of the fascist ideology, Mussolini influenced, or achieved admiration from, a wide variety of political figures. Among the domestic achievements of Mussolini from the years 1924 – 1939 were: his public works programmes such as the taming of the Pontine Marshes, the improvement of job opportunities, and public transport. Mussolini also solved the Roman Question by concluding the Lateran Treaty between the Kingdom of Italy and the Holy See. He is also credited with securing economic success in Italy's colonies and commercial dependencies. On 10 June 1940, Mussolini led Italy into World War II on the side of the Axis despite initially siding with France against Germany in the early 1930s. Believing the war would be short-lived, he declared war on France and Great Britain in order to gain territories in the peace treaty that would soon follow. Three years later, Mussolini was deposed at the Grand Council of Fascism, prompted by the Allied invasion. Soon after his incarceration began, Mussolini was rescued from prison in the daring Gran Sasso raid by German special forces. Following his rescue, Mussolini headed the Italian Social Republic in parts of Italy that were not occupied by Allied forces. In late April 1945, with total defeat looming, Mussolini attempted to escape to Switzerland, only to be quickly captured and summarily executed near Lake Como by Italian partisans. His body was then taken to Milan where it was hung upside down at a petrol station for public viewing and to provide confirmation of his demise.

Mussolini was born in Dovia di Predappio, a small town in the province of Forlì in Emilia-Romagna on 29 July 1883. In the Fascist era, Predappio was dubbed "Duce's town", and Forlì was "Duce's city". Pilgrims went to Predappio and Forlì, to see the birthplace of Mussolini. His father Alessandro Mussolini was a blacksmith and an Anarchist activist, while his mother Rosa Mussolini, née Maltoni, a devoutly Catholic schoolteacher. Owing to his father's political leanings, Mussolini was named Benito after Mexican reformist President Benito Juárez, while his middle names Andrea and Amilcare were from Italian socialists Andrea Costa and Amilcare Cipriani. Benito was the eldest of his parents' three children. His siblings Arnaldo and Edvige followed. As a young boy, Mussolini would spend time helping his father in his blacksmithing. Mussolini's early political views were heavily influenced by his father, Alessandro Mussolini, a revolutionary socialist who idolized 19th century Italian nationalist figures with humanist tendencies such as Carlo Pisacane, Giuseppe Mazzini, and Giuseppe Garibaldi. His father's political outlook combined views of anarchist figures like Carlo Cafiero and Mikhail Bakunin, the military authoritarianism of Garibaldi, and the nationalism of Mazzini. In 1902, at the anniversary of Garibaldi's death, Benito Mussolini made a public speech in praise of the republican nationalist. The conflict between his parents about religion meant that, unlike most Italians, Mussolini was not baptised at birth and would not be until much later in life. However, as a compromise with his mother, Mussolini was sent to a boarding school run by Salesian monks. Mussolini was rebellious and was soon expelled after a series of behaviour related incidents, including throwing stones at the congregation after Mass, stabbing a fellow student in the hand and throwing an inkpot at a teacher. After joining a new school, Mussolini achieved good grades, and qualified as an elementary schoolmaster in 1901.

In 1902, Mussolini emigrated to Switzerland, partly to avoid military service. He worked briefly in Geneva, Fribourg and Bern as a stone mason, but was unable to find a permanent job in Switzerland. During this time he studied the ideas of the philosopher Friedrich Nietzsche, the sociologist Vilfredo Pareto, and the syndicalist Georges Sorel. Mussolini also later credited the Marxist Charles Péguy and the syndicalist Hubert Lagardelle as some of his influences. Sorel's emphasis on the need for overthrowing decadent liberal Democracy and Capitalism by the use of violence, direct action, the general strike, and the use of neo-Machiavellian appeals to emotion, impressed Mussolini deeply. Mussolini became active in the Italian socialist movement in Switzerland, working for the paper L'Avvenire del Lavoratore, organizing meetings, giving speeches to workers and serving as secretary of the Italian workers' union in Lausanne. In 1903, he was arrested by the Bernese police because of his advocacy of a violent general strike, spent two weeks in jail, was deported to Italy, set free there, and returned to Switzerland. In 1904, after having been arrested again in Lausanne for falsifying his papers, he returned to Italy to take advantage of an amnesty for desertion of which he had been convicted in absentia.

He subsequently volunteered for military service in the Italian Army. After serving for two years in the military (from January 1905 until September 1906), he returned to teaching.

In February 1908, Mussolini once again left Italy, this time to take the job as the secretary of the labor party in the Italian speaking city of Trento, which at the time was under control of Austria-Hungary. He also did office work for the local Socialist Party, and edited its newspaper L'Avvenire del Lavoratore (The Future of the Worker). Returning to Italy, he spent a brief time in the Italian city of Milan, and then in 1910 he returned to his hometown of Forli, where he edited the weekly Lotta di classe (The Class Struggle). During this time, he published Il Trentino veduto da un Socialista (Trento as seen by a Socialist) in the radical periodical La Voce. He also wrote several essays about German literature, some stories, and one novel: L'amante del Cardinale: Claudia Particella, romanzo storico (The Cardinal's Mistress). This novel he co-wrote with Santi Corvaja, and was published as a serial book in the Trento newspaper Il Popolo. It was released in installments from Jan. 20 to May 11, 1910  The novel was bitterly anticlerical, and years later was withdrawn from circulation after Mussolini made a truce with the Vatican.

By now, he was considered to be one of Italy's most prominent Socialists. In September 1911, Mussolini participated in a riot, led by Socialists, against the Italian war in Libya. He bitterly denounced Italy's "imperialist war" to capture the Libyan capital city of Tripoli, an action that earned him a five-month jail term. After his release, he helped expel from the ranks of the Socialist party by two 'revisionists' who had supported the war, Ivanoe Bonomi, and Leonida Bissolati. As a result of this, he was rewarded the editorship of the Socialist Party newspaper Avanti! Under his leadersip, its circulation soon rose from 20,000 to 100,000. In 1913, he published Giovanni Hus, il veridico (Jan Hus, true prophet), an historical and political biography about the life and mission of the Czech ecclesiastic reformer Jan Hus, and his militant followers, the Hussites. During this socialist period of his life Mussolini sometimes used the pen name "Vero Eretico“ (sincere misbeliever). While Mussolini was associated with socialism, he also was supportive of figures who opposed egalitarianism. For instance Mussolini was influenced by Nietszche's anti-Christian ideas and negation of God's existence. Mussolini saw Nietzsche as similar to Jean-Marie Guyau, who advocated a philosophy of action. Mussolini's use of Nietzsche made him a highly unorthodox socialist, due to Nietzsche's promotion of elitism and anti-egalitarian views. Mussolini felt that socialism had faltered due to the failures of Marxist determinism and social democratic reformism, and believed that Nietzsche's ideas would strengthen socialism. While associated with socialism, Mussolini's writings eventually indicated that he had abandoned Marxism and egalitarianism in favour of Nietzsche's übermensch concept and anti-egalitarianism.

With the outbreak of World War I a number of socialist parties initially supported the war when it began in August 1914. Once the war began, Austrian, British, French, German and Russian socialists followed the rising nationalist current by supporting their country's intervention in the war. The outbreak of the war had resulted in a surge of Italian nationalism and the war supported by a variety of political factions. One of the most prominent and popular Italian nationalist supporters of the war was Gabriele d'Annunzio who promoted Italian irredentism and helped sway the Italian public to support intervention in the war. The Italian Liberal Party under the leadership of Paolo Boselli promoted intervention in the war on the side of the Allies and utilized the Dante Aligheri Society to promote Italian nationalism. Italian socialists were divided on whether to support the war or oppose it. Prior to Mussolini making a position on the war, a number of revolutionary syndicalists had announced their support of intervention, including Alceste De Ambris, Filippo Corridoni, and Angelo Oliviero Olivetti. However the Italian Socialist Party decided to oppose the war after anti-militarist protestors had been killed, resulting in a general strike called Red Week.

Mussolini initially held official support for the party's decision an in an August 1914 article, Mussolini wrote "Down with the War. We remain neutral." However he saw the war as an opportunity, both for his own ambitions as well as those of socialists and Italians. He was influenced by anti-Austrian Italian nationalist sentiments, believing that the war offered Italians in Austria-Hungary the chance to liberate themselves from rule of the Habsburgs. He eventually decided to declare support for the war by appealing to the need for socialists to overthrow the Hohenzollern and Habsburg monarchies in Germany and Austria-Hungary whom he claimed had consistently repressed socialism. He further justified his position by denouncing the Central Powers for being reactionary powers; for pursuing imperialist designs against Belgium and Serbia as well as historically against Denmark, France, and against Italians, since hundreds of thousands of Italians were under Habsburg rule. He claimed that the fall of Hohenzollern and Habsburg monarchies and the repression of "reactionary" Turkey would create conditions beneficial for the working class. While he was supportive of the Entente powers, Mussolini responded to the conservative nature of Tsarist Russia by claiming that the mobilization required for the war would undermine Russia's reactionary authoritarianism and the war would bring Russia to social revolution. He claimed that for Italy the war would complete the process of Risorgimento by uniting the Italians in Austria-Hungary into Italy and by allowing the common people of Italy to be participating members of the Italian nation in what would be Italy's first national war. Thus he claimed that the vast social changes that the war could offer meant that it should be supported as a revolutionary war.

As Mussolini's support for the intervention solidified, he became in conflict with socialists who opposed the war. He attacked the opponents of the war and claimed that those proletarians who supported pacifism were out of step with the proletarians who had joined the rising interventionist vanguard that was preparing Italy for a revolutionary war. He began to criticize the Italian Socialist Party and socialism itself for having failed to recognize the national problems that had led to the outbreak of the war. He was expelled from the party due to his support of intervention.

The following excerpts are from a police report prepared by the Inspector-General of Public Security in Milan, G. Gasti that describe his background and his position on the First World War that resulted in his ouster from the Italian Socialist Party. The Inspector General wrote:

Regarding Mussolini Professor Benito Mussolini, ...38, revolutionary socialist, has a police record; elementary school teacher qualified to teach in secondary schools; former first secretary of the Chambers in Cesena, Forli, and Ravenna; after 1912 editor of the newspaper Avanti! to which he gave a violent suggestive and intransigent orientation. In October 1914, finding himself in opposition to the directorate of the Italian Socialist party because he advocated a kind of active neutrality on the part of Italy in the War of the Nations against the party's tendency of absolute neutrality, he withdrew on the twentieth of that month from the directorate of Avanti! Then on the fifteenth of November [1914], thereafter, he initiated publication of the newspaper Il Popolo d'Italia, in which he supported -- in sharp contrast to Avanti! and amid bitter polemics against that newspaper and its chief backers -- the thesis of Italian intervention in the war against the militarism of the Central Empires. For this reason he was accused of moral and political unworthiness and the party thereupon decided to expel him... Thereafter he [...] undertook a very active campaign on behalf of Italian intervention, participating in demonstrations in the piazzas and writing quite violent articles in Popolo d'Italia...

In his summary, the Inspector also notes:

"He was the ideal editor of 'Avanti!' for the Socialists. In that line of work he was greatly esteemed and beloved. Some of his former comrades and admirers still confess that there was no one who understood better how to interpret the spirit of the proletariat and there was no one who did not observe his apostasy with sorrow. This came about not for reasons of self-interest or money. He was a sincere and passionate advocate, first of vigilant and armed neutrality, and later of war; and he did not believe that he was compromising with his personal and political honesty by making use of every means -- no matter where they came from or wherever he might obtain them -- to pay for his newspaper, his program and his line of action. This was his initial line. It is difficult to say to what extent his socialist convictions (which he never either openly or privately abjure) may have been sacrificed in the course of the indispensable financial deals which were necessary for the continuation of the struggle in which he was engaged... But assuming these modifications did take place... he always wanted to give the appearance of still being a socialist, and he fooled himself into thinking that this was the case."

After being ousted by the Italian Socialist Party for his support of Italian intervention, Mussolini made a radical transformation, ending his support for class conflict and joining in support of revolutionary nationalism transcending class lines. He formed the pro-interventionist newspaper Il Popolo d'Italia and the Fasci Riviluzionario d'Azione Internazionalista ("Revolutionary Fasci for International Action") in October 1914. His nationalist support of intervention enabled him to raise funds from Ansaldo (an armaments firm) and other companies to create Il Popolo d'Italia to convince socialists and revolutionaries to support the war. Further funding for Mussolini's Fascists during the war came from the French sources beginning in May 1915. A major source of this funding from France is believed to have probably been from French socialists who sent support to dissident socialists who wanted Italian intervention on France's side.

On 5 December 1914, Mussolini denounced orthodox socialism for having failed to recognize that the war had brought about national identity and loyalty as being of greater significance than class distinction. His transformation was fully demonstrated in a speech he made in which he acknowledged the nation as an entity, a notion that he had previously rejected prior to the war, saying:

The nation has not disappeared. We used to believe that the concept was totally without substance. Instead we see the nation arise as a palpitating reality before us! ... Class cannot destroy the nation. Class reveals itself as a collection of interests — but the nation is a history of sentiments, traditions, language, culture, and race. Class can become an integral part of the nation, but the one cannot eclipse the other.

The class struggle is a vain formula, without effect and consequence wherever one finds a people that has not integrated itself into its proper linguistic and racial confines — where the national problem has not been definitely resolved. In such circumstances the class movement finds itself impaired by an inauspicious historic climate.

Mussolini continued to promote the need of a revolutionary vanguard elite to lead society, but he no longer advocated a proletarian vanguard but instead a vanguard led by dynamic and revolutionary people of any social class. Though he denounced orthodox socialism and class conflict, he maintained at the time that he was a nationalist socialist and a supporter of the legacy of nationalist socialists in Italy's history, such as Giuseppe Garibaldi, Giuseppe Mazzini, and Carlo Pisacane. As for the Italian Socialist Party and its support of orthodox socialism, he claimed that his failure as a member of the party to revitalize and transform it to recognize the contemporary reality revealed the hopelessness of orthodox socialism as outdated and a failure. This perception of the failure of orthodox socialism in the light of the outbreak of World War I was not solely held by Mussolini, other pro-interventionist Italian socialists such as Filippo Corridoni and Sergio Panunzio had also denounced classical Marxism in favour of intervention.

These basic political views and principles formed the basis of Mussolini's newly formed political movement, the Fasci Riviluzionario d'Azione Internazionalista in 1914, who called themselves Fascisti (Fascists). At this time, the Fascists did not have an integrated set of policies and the movement was very small, ineffective in its attempts to hold mass meetings, and was regularly harassed by government authorities and orthodox socialists. Antagonism between the interventionists, including the Fascists, versus the anti-interventionist orthodox socialists resulted in violence between the Fascists and socialists. The opposition and attacks by the anti-interventionist revolutionary socialists against the Fascists and other interventionists were so violent that even democratic socialists who opposed the war such as Anna Kulliscioff said that the Italian Socialist Party had gone too far in a campaign of silencing the freedom of speech of supporters of the war. These early hostilities between the Fascists and the revolutionary socialists shaped Mussolini's conception of the nature of Fascism in its support of political violence. Mussolini became an ally with the irredentist politician and journalist Cesare Battisti, and like him he entered the Army and served in the war. "He was sent to the zone of operations where he was seriously injured by the explosion of a grenade." The inspector continues:

"He was promoted to the rank of corporal "for merit in war." The promotion was recommended because of his exemplary conduct and fighting quality, his mental calmness and lack of concern for discomfort, his zeal and regularity in carrying out his assignments, where he was always first in every task involving labor and fortitude."

Mussolini's military experience is told in his work Diario Di Guerra. Overall, he totalled about nine months of active, front-line trench warfare. During this time, he contracted paratyphoid fever. His military exploits ended in 1917 when he was wounded accidentally by the explosion of a mortar bomb in his trench. He was left with at least 40 shards of metal in his body. He was discharged from the hospital in August 1917 and resumed his editor-in-chief position at his new paper, Il Popolo d'Italia. He wrote there positive articles about Czechoslovak Legions in Italy.

On 25 December 1915, in Trevalglio, he contracted a marriage with his fellow countrywoman Rachele Guidi, who had already born him a daughter, Edda, at Forli in 1910. In 1915, he had a son with Ida Dalser, a woman born in Sopramonte, a village near Trento. He legally recognized this son on 11 January 1916.

By the time Mussolini returned from Allied service in World War I, he had decided that socialism as a doctrine had largely been a failure. In 1917, Mussolini got his start in politics with the help of a £100 weekly wage from MI5, the British Security Service; this help was authorised by Sir Samuel Hoare. In early 1918, Mussolini called for the emergence of a man "ruthless and energetic enough to make a clean sweep" to revive the Italian nation. Much later in life Mussolini said he felt by 1919 "Socialism as a doctrine was already dead; it continued to exist only as a grudge". On 23 March 1919, Mussolini reformed the Milan fascio as the Fasci Italiani di Combattimento (Italian Combat Squad), consisting of 200 members.

An important factor in fascism gaining support in its earliest stages was the fact that it claimed to oppose discrimination based on social class and was strongly opposed to all forms of class war. Fascism instead supported nationalist sentiments such as a strong unity, regardless of class, in the hopes of raising Italy up to the levels of its great Roman past. The ideological basis for fascism came from a number of sources. Mussolini utilized works of Plato, Georges Sorel, Nietzsche, and the socialist and economic ideas of Vilfredo Pareto, to create fascism. Mussolini admired The Republic, which he often read for inspiration. The Republic held a number of ideas that fascism promoted such as rule by an elite promoting the state as the ultimate end, opposition to democracy, protecting the class system and promoting class collaboration, rejection of egalitarianism, promoting the militarization of a nation by creating a class of warriors, demanding that citizens perform civic duties in the interest of the state, and utilizing state intervention in education to promote the creation of warriors and future rulers of the state. The Republic differed from fascism in that it did not promote aggressive war but only defensive war, unlike fascism it promoted very communist like views on property, and Plato was an idealist focused on achieving justice and morality while Mussolini and fascism were realist, focused on achieving political goals.

Mussolini and the fascists managed to be simultaneously revolutionary and traditionalist; because this was vastly different to anything else in the political climate of the time, it is sometimes described as "The Third Way". The Fascisti, led by one of Mussolini's close confidants, Dino Grandi, formed armed squads of war veterans called Blackshirts (or squadristi) with the goal of restoring order to the streets of Italy with a strong hand. The blackshirts clashed with communists, socialists and anarchists at parades and demonstrations; all of these factions were also involved in clashes against each other. The government rarely interfered with the blackshirts' actions, owing in part to a looming threat and widespread fear of a communist revolution. The Fascisti grew so rapidly that within two years, it transformed itself into the National Fascist Party at a congress in Rome. Also in 1921, Mussolini was elected to the Chamber of Deputies for the first time. In the meantime, from about 1911 until 1938, Mussolini had various affairs with the Jewish author and academic Margherita Sarfatti, called the "Jewish Mother of Fascism" at the time.

The March on Rome was a coup d'état by which Mussolini's National Fascist Party came to power in Italy and ousted Prime Minister Luigi Facta. The "march" took place in 1922 between 27–29 October. On 28 October King Victor Emmanuel III refused his support to Facta and handed over power to Mussolini. Mussolini was supported by the military, the business class, and the liberal right-wing.

As Prime Minister, the first years of Mussolini's rule were characterized by a right-wing coalition government composed of Fascists, nationalists, liberals and two Catholic clerics from the Popular Party. The Fascists made up a small minority in his original governments. Mussolini's domestic goal, however, was the eventual establishment of a totalitarian state with himself as supreme leader (Il Duce) a message that was articulated by the Fascist newspaper Il Popolo, which was now edited by Mussolini's brother, Arnaldo. To that end, Mussolini obtained from the legislature dictatorial powers for one year (legal under the Italian constitution of the time). He favored the complete restoration of state authority, with the integration of the Fasci di Combattimento into the armed forces (the foundation in January 1923 of the Milizia Volontaria per la Sicurezza Nazionale) and the progressive identification of the party with the state. In political and social economy, he passed legislation that favored the wealthy industrial and agrarian classes (privatisations, liberalisations of rent laws and dismantlement of the unions).

In 1923, Mussolini sent Italian forces to invade Corfu during the "Corfu Incident." In the end, the League of Nations proved powerless and Greece was forced to comply with Italian demands.

In June 1923, the government passed the Acerbo Law, which transformed Italy into a single national constituency. It also granted a two-thirds majority of the seats in Parliament to the party or group of parties which had obtained at least 25% of the votes. This law was applied in the elections of 6 April 1924. The "national alliance", consisting of Fascists, most of the old Liberals and others, won 64% of the vote largely by means of violence and voter intimidation. These tactics were especially prevalent in the south. The assassination of the socialist deputy Giacomo Matteotti, who had requested the annulment of the elections because of the irregularities committed, provoked a momentary crisis of the Mussolini government. The murderer, a squadrista named Amerigo Dumini, reported to Mussolini soon after the murder. Mussolini ordered a cover-up, but witnesses saw the car used to transport Matteotti's body parked outside Matteotti's residence, which linked Dumini to the murder. The Matteotti crisis provoked cries for justice against the murder of an outspoken critic of Fascist violence. Mussolini later confessed that a few resolute men could have alerted public opinion and started a coup that would have swept fascism away. Dumini was imprisoned for two years. On his release Dumini allegedly told other people that Mussolini was responsible, for which he served further prison time. For the next 15 years, Dumini received an income from Mussolini, the Fascist Party, and other sources.

The opposition parties responded weakly or were generally unresponsive. Many of the socialists, liberals and moderates boycotted Parliament in the Aventine Secession, hoping to force Victor Emmanuel to dismiss Mussolini. Despite the leadership of communists such as Antonio Gramsci, socialists such as Pietro Nenni and liberals such as Piero Gobetti and Giovanni Amendola, a mass antifascist movement never crystallized. The king, fearful of violence from the Fascist squadristi, kept Mussolini in office. Because of the boycott of Parliament, Mussolini could pass any legislation unopposed. The political violence of the squadristi had worked, for there was no popular demonstration against the murder of Matteotti. Within his own party, Mussolini faced doubts and dissension during these critical weeks.

On 31 December 1924, MVSN consuls met with Mussolini and gave him an ultimatum — crush the opposition or they would do so without him. Fearing a revolt by his own militants, Mussolini decided to drop all trappings of democracy. On 3 January 1925, Mussolini made a truculent speech before the Chamber in which he took responsibility for squadristi violence (though he did not mention the assassination of Matteotti). He promised a crackdown on dissenters. Before his speech, MVSN detachments beat up the opposition and prevented opposition newspapers from publishing. Mussolini correctly predicted that as soon as public opinion saw him firmly in control the "fence-sitters", the silent majority and the "place-hunters" would all place themselves behind him. Mussolini's influence in propaganda was such that he had surprisingly little opposition to suppress. Nonetheless, he was "slightly wounded in the nose" when he was shot on 7 April 1926 by Violet Gibson, an Irish woman and daughter of Baron Ashbourne. On 31 October 1926, 15 year old Anteo Zamboni attempted to shoot Mussolini in Bologna. Zamboni was lynched on the spot. Mussolini also survived a failed assassination attempt in Rome by anarchist Gino Lucetti, and a planned attempt by the Italian anarchist Michele Schirru, which ended with Schirru's capture and execution. Members of TIGR, a Slovene anti-fascist group, plotted to kill Mussolini in Caporetto in 1938, but their attempt was unsuccessful.

At various times after 1922, Mussolini personally took over the ministries of the interior, foreign affairs, colonies, corporations, defense, and public works. Sometimes he held as many as seven departments simultaneously, as well as the premiership. He was also head of the all-powerful Fascist Party and the armed local fascist militia, the MVSN or "Blackshirts," who terrorised incipient resistances in the cities and provinces. He would later form the OVRA, an institutionalised secret police that carried official state support. In this way he succeeded in keeping power in his own hands and preventing the emergence of any rival. Between 1925 and 1927, Mussolini progressively dismantled virtually all constitutional and conventional restraints on his power, thereby building a police state. A law passed on Christmas Eve 1925 changed Mussolini's formal title from "president of the Council of Ministers" to "head of the government." He was no longer responsible to Parliament and could only be removed by the king. While the Italian constitution stated that ministers were only responsible to the sovereign, in practice it had become all but impossible to govern against the express will of Parliament. The Christmas Eve law ended this practice, and also made Mussolini the only person competent to determine the body's agenda. Local autonomy was abolished, and podestàs appointed by the Italian Senate replaced elected mayors and councils.

All other parties were outlawed in 1928, though in practice Italy had been a one-party state since Mussolini's 1925 speech. In the same year, an electoral law abolished parliamentary elections. Instead, the Grand Council of Fascism selected a single list of candidates to be approved by plebiscite. The Grand Council had been created five years earlier as a party body but was "constitutionalised" and became the highest constitutional authority in the state. On paper, the Grand Council had the power to recommend Mussolini's removal from office, and was thus theoretically the only check on his power. However, only Mussolini could summon the Grand Council and determine its agenda. To gain control of the South, especially Sicily, he appointed Cesare Mori as a Prefect of the city of Palermo, with the charge of eradicating the Mafia at any price. In the telegram, Mussolini wrote to Mori:

"Your Excellency has carte blanche, the authority of the State must absolutely, I repeat absolutely, be re-established in Sicily. If the laws still in force hinder you, this will be no problem, as we will draw up new laws."

He did not hesitate laying siege to towns, using torture, and holding women and children as hostages to oblige suspects to give themselves up. These harsh methods earned him the nickname of "Iron Prefect". However, in 1927 Mori's inquiries brought evidence of collusion between the Mafia and the Fascist establishment, and he was dismissed for length of service in 1929. Mussolini nominated Mori as a senator, and fascist propaganda claimed that the Mafia had been defeated.

Mussolini launched several public construction programs and government initiatives throughout Italy to combat economic setbacks or unemployment levels. His earliest, and one of the best known, was Italy's equivalent of the Green Revolution, known as the "Battle for Grain", in which 5,000 new farms were established and five new agricultural towns on land reclaimed by draining the Pontine Marshes. In Sardinia, a model agricultural town was founded and named Mussolinia, but has long since been renamed Arborea. This town was the first of what Mussolini hoped would have been thousands of new agricultural settlements across the country. This plan diverted valuable resources to grain production, away from other less economically viable crops. The huge tariffs associated with the project promoted widespread inefficiencies, and the government subsidies given to farmers pushed the country further into debt. Mussolini also initiated the "Battle for Land", a policy based on land reclamation outlined in 1928. The initiative had a mixed success; while projects such as the draining of the Pontine Marsh in 1935 for agriculture were good for propaganda purposes, provided work for the unemployed and allowed for great land owners to control subsidies, other areas in the Battle for Land were not very successful. This program was inconsistent with the Battle for Grain (small plots of land were inappropriately allocated for large-scale wheat production), and the Pontine Marsh was lost during World War II. Fewer than 10,000 peasants resettled on the redistributed land, and peasant poverty remained high. The Battle for Land initiative was abandoned in 1940.

He also combated an economic recession by introducing the "Gold for the Fatherland" initiative, by encouraging the public to voluntarily donate gold jewellery such as necklaces and wedding rings to government officials in exchange for steel wristbands bearing the words "Gold for the Fatherland". Even Rachele Mussolini donated her own wedding ring. The collected gold was then melted down and turned into gold bars, which were then distributed to the national banks.

Mussolini pushed for government control of business: by 1935, Mussolini claimed that three quarters of Italian businesses were under state control. That same year, he issued several edicts to further control the economy, including forcing all banks, businesses, and private citizens to give up all their foreign-issued stocks and bonds to the Bank of Italy. In 1938, he also instituted wage and price controls. He also attempted to turn Italy into a self-sufficient autarky, instituting high barriers on trade with most countries except Germany. In 1943 he proposed the theory of economic socialization.

Mussolini's foremost priority was the subjugation of the minds of the Italian people and the use of propaganda to do so. Press, radio, education, films — all were carefully supervised to create the illusion that fascism was the doctrine of the twentieth century, replacing liberalism and democracy. The principles of this doctrine were laid down in the article on fascism, written by Giovanni Gentile and signed by Mussolini that appeared in 1932 in the Enciclopedia Italiana. In 1929, a concordat with the Vatican was signed, the Lateran treaties, by which the Italian state was at last recognised by the Roman Catholic Church, and the independence of Vatican City was recognised by the Italian state. The 1929 treaty included a legal provision whereby the Italian government would protect the honor and dignity of the Pope by prosecuting offenders. In 1927, Mussolini was re-baptised by a Roman Catholic priest in an attempt to assuage certain Catholic opposition, who were still critical. After 1929, Mussolini, with his anti-Communist doctrines, convinced many Catholics to actively support him. In the encyclical Non abbiamo bisogno, Pope Pius XI attacked the Fascist regime for its policy against the Catholic Action and certain tendencies to overrule Catholic education morals.

The law codes of the parliamentary system were rewritten under Mussolini. All teachers in schools and universities had to swear an oath to defend the fascist regime. Newspaper editors were all personally chosen by Mussolini and no one who did not possess a certificate of approval from the fascist party could practice journalism. These certificates were issued in secret; Mussolini thus skillfully created the illusion of a "free press". The trade unions were also deprived of any independence and were integrated into what was called the "corporative" system. The aim (never completely achieved), inspired by medieval guilds, was to place all Italians in various professional organizations or "corporations", all of which were under clandestine governmental control.

Large sums of money were spent on highly visible public works, and on international prestige projects such as the SS Rex Blue Riband ocean liner and aeronautical achievements such as the world's fastest seaplane the Macchi M.C.72 and the transatlantic flying boat cruise of Italo Balbo, who was greeted with much fanfare in the United States when he landed in Chicago.

Nationalists in the years after the war thought of themselves as combating both liberal and domineering institutions created by cabinets such as those of Giovanni Giolitti, including traditional schooling. Futurism, a revolutionary cultural movement which would serve as a catalyst for Fascism, argued for "a school for physical courage and patriotism", as expressed by Filippo Tommaso Marinetti in 1919. Marinetti expressed his disdain for "the by now prehistoric and troglodyte Ancient Greek and Latin courses", arguing for their replacement with exercise modelled on those of the Arditi soldiers ("[learning] to advance on hands and knees in front of razing machine gun fire; to wait open-eyed for a crossbeam to move sideways over their heads etc."). It was in those years that the first Fascist youth wings were formed Avanguardie Giovanili Fasciste (Fascist Youth Vanguards) in 1919, and Gruppi Universitari Fascisti (Fascist University Groups), in 1922).

After the March on Rome that brought Benito Mussolini to power, the Fascists started considering ways to ideologize the Italian society, with an accent on schools. Mussolini assigned former ardito and deputy-secretary for Education Renato Ricci the task of "reorganizing the youth from a moral and physical point of view". Ricci sought inspiration with Robert Baden-Powell, the founder of Scouting, meeting with him in England, as well as with Bauhaus artists in Germany. The Opera Nazionale Balilla was created through Mussolini's decree of 3 April 1926, and was led by Ricci for the following eleven years. It included children between the ages of 8 and 18, grouped as the Balilla and the Avanguardisti. According to Mussolini: "Fascist education is moral, physical, social, and military: it aims to create a complete and harmoniously developed human, a fascist one according to our views". Mussolini structured this process taking in view the emotional side of childhood: "Childhood and adolescence alike (...) cannot be fed solely by concerts, theories, and abstract teaching. The truth we aim to teach them should appeal foremost to their fantasy, to their hearts, and only then to their minds". The "educational value set through action and example" was to replace the established approaches. Fascism opposed its version of idealism to prevalent rationalism, and used the Opera Nazionale Balilla to circumvent educational tradition by imposing the collective and hierarchy, as well as Mussolini's own personality cult.

In foreign policy, Mussolini soon shifted from the pacifist anti-imperialism of his lead-up to power to an extreme form of aggressive nationalism. He dreamt of making Italy a nation that was "great, respected and feared" throughout Europe, and indeed the world. An early example was his bombardment of Corfu in 1923. Soon after he succeeded in setting up a puppet regime in Albania and in ruthlessly consolidating Italian power in Libya, which had been loosely a colony since 1912. It was his dream to make the Mediterranean mare nostrum ("our sea" in Latin), and he established a large naval base on the Greek island of Leros to enforce a strategic hold on the eastern Mediterranean. However, his first 'baby steps' into foreign policy seemed to portray him as a 'statesman', for he participated in the Locarno Treaties of 1925 and the attempted Four Power Pact of 1933 was Mussolini's brainchild. Following the Stresa Front against Germany in 1935, however, Mussolini's policy took a dramatic turning point and revealed itself once again to be that of an aggressive nature. This domino effect of war began with the Second Italo-Abyssinian War.

In an effort to realise an Italian Empire or the New Roman Empire as supporters called it, Italy set its sights on Ethiopia with an invasion that was carried out rapidly. Italy's forces were far superior to the Abyssinian forces, especially in regards to air power and were soon declared victors. Emperor Haile Selassie was forced to flee the country, with Italy entering the capital Addis Ababa to proclaim an Empire by May 1936, making Ethiopia part of Italian East Africa. Although all of the major European powers of the time had also colonised parts of Africa and committed atrocities in their colonies, the Scramble for Africa had finished by the beginning of the twentieth century. The international mood was now against colonialist expansion and Italy's actions were condemned. Retroactively, Italy was criticised for its use of mustard gas and phosgene against its enemies and also for its zero tolerance approach to enemy guerrillas, allegedly authorised by Mussolini. When Rodolfo Graziani the viceroy of Ethiopia was nearly assassinated at an official ceremony, with the guerrilla bomb exploding among the people there, a very stronghanded reaction followed against the guerrillas, including those who were prisoners according to the International Red Cross. The IRC also alleged that Italy bombed their tents in areas of guerrillas military encampment; though Italy denied it had intended to, insisting that the rebels were targeted. It was not until the East African Campaign's conclusion in 1941 that Italy lost its East African territories, after taking on a fourteen nation allied force.

Italian military help to Nationalists against the anti-clerical and anti-Catholic atrocities committed by the Republican side worked well in Italian propaganda targeting Catholics. On 27 July 1936 the first squadron of Italian airplanes sent by Benito Mussolini arrived in Spain. This active intervention in 1936 – 1939 on the side of Franco in the Spanish Civil War ended any possibility of reconciliation with France and Britain. As a result, his relationship with Adolf Hitler became closer, and he chose to accept the German annexation of Austria in 1938 and the dismemberment of Czechoslovakia in 1939. At the Munich Conference in September 1938, he posed as a moderate working for European peace, helping Nazi Germany seize control of the Sudetenland. His "axis" with Germany was confirmed when he made the "Pact of Steel" with Hitler in May 1939, as the previous "Rome-Berlin Axis" of 1936 had been unofficial. Members of TIGR, a Slovene anti-fascist group, plotted to kill Mussolini in Kobarid in 1938, but their attempt was unsuccessful.

The relationship between Mussolini and Adolf Hitler was a contentious one early on. While Hitler cited Mussolini as an influence, Mussolini had little regard for Hitler, especially after the Nazis had assassinated his friend and ally, Engelbert Dollfuss the Austrofascist dictator of Austria in 1933. With the assassination of Dollfuss, Mussolini attempted to distance himself from Hitler by rejecting much of the racialism (particularly Nordicism and Germanicism) and anti-Semitism espoused by the German radical. Mussolini during this period rejected biological racism, at least in the Nazi sense, and instead emphasized "Italianising" the parts of the Italian Empire he had desired to build. He declared that the ideas of Eugenics and the racially charged concept of an Aryan nation were not possible. Mussolini was particularly sensitive to German accusations that the Italians were a mongrelized race. He retaliated by mockingly referring to the Germans' own lack of racial purity on several occasions. When discussing the Nazi decree that the German people must carry a passport with either Aryan or Jewish racial affiliation marked on it, in the summer of 1934, Mussolini wondered how they would designate membership in the "Germanic race":

When German-Jewish journalist Emil Ludwig asked about his views on race, Mussolini exclaimed:

In a speech given in Bari, he reiterated his attitude toward German racism:

However Mussolini's rejection of both racialism and the importance of race in 1934 during the height of his antagonism towards Hitler contradicted his own earlier statements about race, such as in 1928 in which he emphasized the importance of race:

Though Italian Fascism variated its official positions on race from the 1920s to 1934, ideologically Italian fascism did not originally discriminate against the Italian Jewish community: Mussolini recognised that a small contingent had lived there "since the days of the Kings of Rome" and should "remain undisturbed". There were even some Jews in the National Fascist Party, such as Ettore Ovazza who in 1935 founded the Jewish Fascist paper La Nostra Bandiera ("Our Flag").

By 1938, the enormous influence Hitler now had over Mussolini became clear with the introduction of the Manifesto of Race. The Manifesto, which was closely modeled on the Nazi Nuremberg laws, stripped Jews of their Italian citizenship and with it any position in the government or professions. The German influence on Italian policy upset the established balance in Fascist Italy and proved highly unpopular to most Italians, to the extent that Pope Pius XII sent a letter to Mussolini protesting against the new laws. It has been widely speculated that Mussolini's reasoning to adopt the Manifesto of Race in 1938 was merely tactical, in order to strengthen Italy's relations with Germany. In December 1943, Mussolini made a confession to Bruno Spampanato that seems to indicate that he regretted the Manifesto of Race, as Mussolini put it:

Mussolini also reached out to the Muslims in his empire and in the new Muslim states in the Middle East. In 1937, the Muslims of Libya pronounced him as the "Protector of Islam."

Mussolini had imperial designs on Tunisia, and had some support in that country. In April 1939 with world focus on Hitler's invasion of Czechoslovakia, looking to restore honour from a much older defeat Italy invaded Albania. Italy defeated Albania within just five days forcing king Zog to flee, setting up a period of Albania under Italy. Until May 1939, the Axis had not been entirely official, however during that month the Pact of Steel treaty was made outlining the "friendship and alliance" between Germany and Italy, signed by each of its foreign ministers. Italy's king Victor Emanuel III was also wary of the pact, favouring the more traditional Italian allies like France.

Hitler was intent on invading Poland, though Galeazzo Ciano warned this would likely lead to war with the Allies. Hitler dismissed Ciano's comment, predicting that instead that Britain and the other Western countries would back down, and he suggested that Italy should invade Yugoslavia. The offer was tempting to Mussolini, but at that stage world war would be a disaster for Italy as the armaments situation from building the Italian Empire thus far was lean. Most significantly, Victor Emmanuel had demanded neutrality in the dispute. Thus when World War II in Europe began on 1 September 1939 with the German invasion of Poland eliciting the response of the United Kingdom and France declaring war on Germany, Italy did not become involved in the conflict. As World War II began, Ciano and Viscount Halifax were holding secret phone conversations. The British wanted Italy on their side against Germany as it had been in World War I. French government opinion was more geared towards action against Italy; they were itching to attack Italy in Libya. However, in September 1939, France swung to the opposite extreme, offering to discuss issues with Italy, but as the French were unwilling to discuss Corsica, Nice and Savoy, Mussolini did not answer.

“	So long as the Duce lives, one can rest assured that Italy will seize every opportunity to achieve its imperialistic aims.	”
—Adolf Hitler, late November 1939

Convinced that the war would soon be over, with a German victory looking likely at that point, Mussolini decided to enter the war on the Axis side. Accordingly, Italy declared war on Britain and France on 10 June 1940. Italy joined the Germans in the Battle of France, fighting the fortified Alpine Line at the border. Just eleven days later, France surrendered to the Axis powers. Included in Italian controlled France was most of Nice and other southeastern counties. Meanwhile in Africa, Mussolini's Italian East Africa forces attacked the British in their Sudan, Kenya and British Somaliland colonies, in what would become known as the East African Campaign. British Somaliland was conquered and became part of Italian East Africa on 3 August 1940, and there were Italian advances in Sudan and Kenya. Just over a month later, the Italian Tenth Army commanded by General Rodolfo Graziani crossed from Italian Libya into Egypt where British forces were located; this would become the Western Desert Campaign. Advances were successful, but the Italians stopped at Sidi Barrani waiting for logistic supplies to catch up. During 25 October 1940, Mussolini sent the Italian Air Corps to Belgium, where the air force took part in the Battle of Britain for around two months. In October, Mussolini also sent Italian forces into Greece starting the Greco-Italian War. After initial success, this backfired as the Greek counterattack proved relentless, resulting in Italy losing one quarter of Albania. Germany soon committed forces to the Balkans to fight the gathering Allies.

Events in Africa had changed by early 1941 as Operation Compass had forced the Italians back into Libya, causing high losses in the Italian Army. Also in the East African Campaign, an attack was mounted against Italian forces. Despite putting up a resistance, they were overwhelmed at the Battle of Keren, and the Italian defense started to crumble with a final defeat in the Battle of Gondar. However, when addressing the Italian public on the events, he was completely open about the situation saying, "We call bread bread and wine wine, and when the enemy wins a battle it is useless and ridiculous to seek, as the English do in their incomparable hypocrisy, to deny or diminish it." Part of his comment was in relation to earlier success the Italians had in Africa, before being defeated by an Allied force later. In danger of losing the control of all Italian possessions in North Africa, Germany finally sent the Afrika Korps to support Italy. Meanwhile Operation Marita took place in Yugoslavia to end the Greco-Italian War, resulting in an Axis victory and the Occupation of Greece by Italy and Germany. With the Axis invasion of the Soviet Union, Mussolini declared war on the Soviet Union in June 1941 and sent an army to fight there. After the Japanese attack on Pearl Harbor, he declared war on the United States on December 11, 1941. An interesting evidence regarding Mussolini's response to the attack on Pearl Harbor comes from the diary of his Foreign Minister Ciano:

"A night telephone call from Ribbentrop. He is overjoyed about the Japanese attack on America. He is so happy about it that I am happy with him, though I am not too sure about the final advantages of what has happened. One thing is now certain, that America will enter the conflict and that the conflict will be so long that she will be able to realize all her potential forces. This morning I told this to the King who had been pleased about the event. He ended by admitting that, in the long run, I may be right. Mussolini was happy, too. For a long time he has favored a definite clarification of relations between America and the Axis".
