Born in Rennes, Boulanger graduated from Saint - Cyr and entered regular service in the French Army in 1856. He fought in the Austro - Sardinian War (he was wounded at Robecchetto, where he received the Légion d'honneur), and in the occupation of Cochin China, after which he became a captain and instructor at Saint - Cyr. During the Franco - Prussian War, Georges Boulanger was noted for his bravery, and soon promoted to chef de bataillon; he was again wounded while fighting at Champigny - sur - Marne (during the Siege of Paris). Subsequently, Boulanger was among the Third Republic military leaders who crushed the Paris Commune in April - May 1871. He was wounded a third time as he led troops to the siege of the Panthéon, and was promoted commandeur of the Légion d'honneur by Patrice Mac - Mahon. However, he was soon demoted (as his position was considered provisional), and his resignation in protest was rejected.

With backing from his direct superior, Henri d'Orléans, duc d'Aumale (incidentally, one of the sons of former king Louis - Philippe), Boulanger was made a brigadier - general in 1880, and in 1882 War Minister Jean - Baptiste Billot appointed him director of infantry at the war office, enabling him to make a name as a military reformer (he took measures to improve morale and efficiency). In 1884 he was appointed to command the army occupying Tunis, but was recalled owing to his differences of opinion with Pierre - Paul Cambon, the political resident. He returned to Paris, and began to take part in politics under the aegis of Georges Clemenceau and the Radicals. In January 1886, when Charles de Freycinet was brought into power, Clemenceau used his influence to secure Boulanger's appointment as War Minister (replacing Jean - Baptiste - Marie Campenon). Clemenceau assumed Boulanger was a republican, because he was known not to attend Mass. However Boulanger would soon prove himself a conservative and monarchist.

It was in the capacity of War Minister that Boulanger gained most popularity. He introduced reforms for the benefit of soldiers (such as allowing soldiers to grow beards) and appealed to the French desire for revenge against Imperial Germany - in doing so, came to be regarded as the man destined to serve that revenge (nicknamed Général Revanche). He also managed to quell the major workers' strike in Decazeville. A minor scandal arose when Philippe, comte de Paris, the nominal inheritor of the French throne in the eyes of Orléanist monarchists, married his daughter Amélie to Portugal's Carlos I, in a lavish wedding that provoked fears of anti - Republican ambitions. The French Parliament hastily passed a law expelling all possible claimants to the crown from French territories. Boulanger found himself in the unusual posture of a monarchist sympathiser forced to communicate to d'Aumale his expulsion from the armed forces. He received the adulation of the public and press after the Sino - French War, when France's victory added Tonkin to its colonial empire. He also vigorously pressed for the accelerated adoption, in 1886, of the new and technically revolutionary Lebel rifle which introduced for the first time smokeless powder high velocity ammunition.

On Freycinet's defeat in December of the same year, Boulanger was retained by René Goblet at the war office. Confident of political support, the general began provoking the Germans: he ordered military facilities to be built in the border region of Belfort, forbade the export of horses to German markets, and even instigated a ban on representations of Lohengrin. Germany responded by calling to arms more than 70,000 reservists in February 1887; after the Schnaebele incident (April 1887), war was averted, but Boulanger was perceived by his supporters as coming out on top against Bismarck. For the Goblet government, Boulanger was an embarrassment and risk, and became engaged in a dispute with Foreign Minister Émile Flourens. On May 17, Goblet was voted out of office and replaced by Maurice Rouvier. The latter sacked Boulanger, and replaced him with Théophile Adrien Ferron on May 30.

The government was astonished by the revelation that Boulanger had received around 100,000 votes for the partial election in Seine, without him even being a candidate. He was removed from the Paris region and sent to the provinces, appointed commander of the troops stationed in Clermont - Ferrand. Upon his departure on July 8, a crowd of ten thousand took the Gare de Lyon by storm, covering his train with posters titled Il reviendra ("He will come back"), and blocking the railway, but he was smuggled through on a switch engine.

The general decided to gather support for his own movement, an eclectic one that capitalized on the frustrations of French conservatism, advocating the three principles of Revanche (Revenge on Germany), Révision (Revision of the Constitution), Restoration (the return to monarchy). The common reference to it has become Boulangisme, a term used by its partisans and adversaries alike. Immediately, the option was backed by notable conservative figures such as Henri Rochefort, Count Arthur Dillon, Alfred Joseph Naquet, Anne de Mortemart - Rochechouart (Duchess of Uzès, who financed him with immense sums), Arthur Meyer, Paul Déroulède (and his Ligue des Patriotes).

After the political corruption scandal surrounding the President's son - in - law Daniel Wilson, who was secretly selling Legion of Honor medals to anyone who wanted one, the Republican government was brought into disrepute and Boulanger's popular appeal rose in contrast. His position became essential after President Jules Grévy was forced to resign due to the scandal: in January 1888, the boulangistes promised to back any candidate for the presidency that would in turn offer his support to Boulanger for the post of War Minister (France was a parliamentary republic). The crisis was cut short by the election of Marie François Sadi Carnot and the appointment of Pierre Tirard as Prime Minister - Tirard refused to include Boulanger in his cabinet. During the period, Boulanger was in Switzerland, where he met with Jérôme Napoleon Bonaparte II, technically a Bonapartist, who offered his full support to the cause. The Bonapartists had attached themselves to the general, and even the Comte de Paris encouraged his followers to support him. Once seen as a republican, Boulanger showed his true colors in the camp of the conservative monarchists. On March 26, 1888 he was expelled from the army. The day after, Daniel Wilson had his imprisonment repealed. It seemed to the French people that honorable generals were punished while corrupt politicians were spared, further increasing Boulanger's popularity.

Although he was not in fact a legal candidate for the French Chamber of Deputies (since he was a military man), Boulanger ran with Bonapartist backing in seven separate départements during the remainder of 1888. Boulangiste candidates were present in every département. Consequently, he and many of his supporters were voted to the Chamber, and accompanied by a large crowd on July 12, the day of their swearing in - the general himself was elected in the constituency of Nord. The boulangistes were, nonetheless, a minority in the Chamber. Since Boulanger could not pass legislation, his actions were directed to maintaining his public image. Neither his failure as an orator nor his defeat in a duel with Charles Thomas Floquet, then an elderly civilian and the minister of the interior, reduced the enthusiasm of his popular following.

During 1888 his personality was the dominating feature of French politics, and, when he resigned his seat as a protest against the reception given by the Chamber to his proposals, constituencies vied with one another in selecting him as their representative. His name was the theme of the popular song C'est Boulanger qu'il nous faut ("Boulanger is the One We Need"), he and his black horse became the idol of the Parisian population, and he was urged to run for the presidency. The general agreed, but his personal ambitions soon alienated his republican supporters, who recognised in him a potential military dictator. Numerous monarchists continued to give him financial aid, even though Boulanger saw himself as a leader rather than a restorer of kings.

In January 1889, he ran as a deputy for Paris, and, after an intense campaign, took the seat with 244,000 votes against the 160,000 of his main adversary. A coup d'état seemed probable and desirable among his supporters. Boulanger had now become a threat to the parliamentary Republic. Had he immediately placed himself at the head of a revolt he might have effected the coup which many of his partisans had worked for, and might even have governed France; but the opportunity passed with his procrastination on January 27. According to Lady Randolph Churchill "[a]ll his thoughts were centred in and controlled by her who was the mainspring of his life. After the plebiscite... he rushed off to Madame Bonnemain's house and could not be found."

Boulanger decided that it would be better to contest the general election and take power legally. This, however, gave his enemies the time they needed to strike back. Ernest Constans, the Minister of the Interior, decided to investigate the matter, and attacked the Ligue des Patriotes using the law banning the activities of secret societies.

Shortly afterward the French government issued a warrant for Boulanger's arrest for conspiracy and treasonable activity. To the astonishment of his supporters, on April 1 he fled from Paris before it could be executed, going first to Brussels and then to London. On April 4, the Parliament stripped him of his immunity from prosecution; the French Senate condemned him, Rochefort, and Count Dillon for treason, sentencing all three to deportation and confinement.

After his flight, support for him dwindled, and the Boulangists were defeated in the general elections of July 1889 (after the government forbade Boulanger from running). Boulanger himself went to live in Jersey before returning to the Ixelles Cemetery in Brussels in September 1891 to commit suicide by a bullet to the head on the grave of his mistress, Madame de Bonnemains (née Marguerite Crouzet) who had died the preceding July. He was interred in the same grave.

Several incidents followed Boulanger's death, including an armed attack carried out by a boulangiste against the Republican politician Jules Ferry, in December of the same year. Although largely discredited, the trend started by Boulanger was still visible inside the far right (the anti - Dreyfusards) during France's next major scandal, the Dreyfus Affair. Israeli historian Zeev Sternhell cites boulangisme as a major influence on Fascism, alongside Anarcho - syndicalism and the Cercle Proudhon.

• "We can finally renounce our unfortunate defensive policy [towards Germany]; France ought to increasingly follow the offensive policy." (1886, during a speech in Libourne)
• "Boulangisme: (...) 'a vague and mystical aspiration of a nation towards a democratic, authoritarian, liberating ideal; the state of mind of a country that is searching, after the various deceptions to which she was exposed by the established parties which she had trusted up to then, and outside the usual ways, something else altogether, without knowing either what or how, and summoning all those who are dissatisfied and vanquished in its search for the unknown.' (...) 'General Boulanger was born out of this state of mind. He did not create the boulangisme, it is boulangisme that created him. He had the chance to arrive at the psychological and spiritual moment from which he profits." (Arthur Meyer in Le Gaulois, October 11, 1889)
• "A Saint Arnaud of the café - concert." (Jules Ferry on Boulanger)
• "Five minutes past midnight, gentlemen. It's been five minutes since boulangisme has started to decrease." (a boulangiste on January 27, immediately after Boulanger's refusal to lead a coup)
• "He died as he has lived: a second lieutenant." (Georges Clemenceau upon hearing news of Boulanger's suicide)

Général Boulanger inspired the Jean Renoir movie Elena and Her Men, a musical fantasy loosely based on the end of his political career. The role of Général François Rollan, a Boulanger - like character, was played by Jean Marais.

IMDB notes that there was also a French television programme about Boulanger in the early 1980s, La Nuit du général Boulanger, where Boulanger is played by Maurice Ronet.

He is quoted as the one who authorised the institution of the "Suicide Bureau" in Guy de Maupassant's short story "The Magic Couch", reportedly "the only good thing he did".
