Ernesto "Che" Guevara (June 14, 1928 – October 9, 1967), commonly known as El Che or simply Che, was an Argentine Marxist revolutionary, physician, author, intellectual, guerrilla leader, diplomat, military theorist, and major figure of the Cuban Revolution. Since his death, his stylized visage has become a ubiquitous counter cultural symbol and global insignia within popular culture.

As a young medical student, Guevara traveled throughout Latin America and was transformed by the endemic poverty he witnessed. His experiences and observations during these trips led him to conclude that the region's ingrained economic inequalities were an intrinsic result of monopoly capitalism, neocolonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social reforms under President Jacobo Arbenz Guzmán, whose eventual CIA-assisted overthrow solidified Guevara's radical ideology. Later, while living in Mexico City, he met Raúl and Fidel Castro, joined their 26th of July Movement, and invaded Cuba aboard the Granma with the intention of overthrowing U.S.-backed Cuban dictator Fulgencio Batista. Guevara soon rose to prominence among the insurgents, was promoted to second-in-command, and played a pivotal role in the successful two year guerrilla campaign that deposed the Batista regime. Following the Cuban Revolution, Guevara performed a number of key roles in the new government. These included reviewing the appeals and firing squads for those convicted as war criminals during the revolutionary tribunals, instituting agrarian reform as minister of industries, serving as both national bank president and instructional director for Cuba’s armed forces, and traversing the globe as a diplomat on behalf of Cuban socialism. Such positions allowed him to play a central role in training the militia forces who repelled the Bay of Pigs Invasion and bringing to Cuba the Soviet nuclear-armed ballistic missiles which precipitated the 1962 Cuban Missile Crisis. Additionally, he was a prolific writer and diarist, composing a seminal manual on guerrilla warfare, along with a best-selling memoir about his youthful motorcycle journey across South America. Guevara left Cuba in 1965 to incite revolutions, first unsuccessfully in Congo-Kinshasa and later in Bolivia, where he was captured by Central Intelligence Agency-assisted Bolivian forces and executed. Guevara remains both a revered and reviled historical figure, polarized in the collective imagination in a multitude of biographies, memoirs, essays, documentaries, songs, and films. Time magazine named him one of the 100 most influential people of the 20th century, while an Alberto Korda photograph of him entitled Guerrillero Heroico, was declared "the most famous photograph in the world."

Ernesto Guevara was born to Celia de la Serna y Llosa and Ernesto Guevara Lynch on June 14, 1928 in Rosario, Argentina, the eldest of five children in a White Argentine family of Spanish, Basque and Irish descent. In lieu of his parents' surnames, his legal name (Ernesto Guevara) will sometimes appear with de la Serna, or Lynch accompanying it. In reference to Che's "restless" nature, his father declared "the first thing to note is that in my son's veins flowed the blood of the Irish rebels." Very early on in life Ernestito (as he was then called) developed an "affinity for the poor." Growing up in a family with leftist leanings, Guevara was introduced to a wide spectrum of political perspectives even as a boy. His father, a staunch supporter of Republicans from the Spanish Civil War, often hosted many veterans from the conflict in the Guevara home. Though suffering crippling bouts of acute asthma that were to afflict him throughout his life, he excelled as an athlete, enjoying swimming, soccer, golf, and shooting; while also becoming an "untiring" cyclist. He was an avid rugby union player, and played at fly-half for the University of Buenos Aires First XV. His rugby playing earned him the nickname "Fuser" — a contraction of El Furibundo (raging) and his mother's surname, de la Serna — for his aggressive style of play. His schoolmates also nicknamed him "Chancho" ("pig"), because he rarely bathed, and proudly wore a "weekly shirt." Guevara learned chess from his father and began participating in local tournaments by age 12. During adolescence and throughout his life he was passionate about poetry, especially that of Pablo Neruda, John Keats, Antonio Machado, Federico García Lorca, Gabriela Mistral, César Vallejo, and Walt Whitman. He could also recite Rudyard Kipling's "If—" and José Hernández's "Martín Fierro" from memory. The Guevara home contained more than 3,000 books, which allowed Guevara to be an enthusiastic and eclectic reader, with interests including Karl Marx, William Faulkner, André Gide, Emilio Salgari and Jules Verne. Additionally, he enjoyed the works of Jawaharlal Nehru, Franz Kafka, Albert Camus, Vladimir Lenin, and Jean-Paul Sartre; as well as Anatole France, Friedrich Engels, H.G. Wells, and Robert Frost.

As he grew older, he developed an interest in the Latin American writers Horacio Quiroga, Ciro Alegría, Jorge Icaza, Rubén Darío, and Miguel Asturias. Many of these authors' ideas he cataloged in his own handwritten notebooks of concepts, definitions, and philosophies of influential intellectuals. These included composing analytical sketches of Buddha and Aristotle, along with examining Bertrand Russell on love and patriotism, Jack London on society, and Nietzsche on the idea of death. Sigmund Freud's ideas fascinated him as he quoted him on a variety of topics from dreams and libido to narcissism and the oedipus complex. His favorite subjects in school included philosophy, mathematics, engineering, political science, sociology, history and archaeology.

In 1948, Guevara entered the University of Buenos Aires to study medicine. But in 1951, he took a year off from studies to embark on a trip traversing South America by motorcycle with his friend Alberto Granado, with the final goal of spending a few weeks volunteering at the San Pablo Leper colony in Peru, on the banks of the Amazon River. On the way to Machu Picchu high in the Andes, he was struck by the crushing poverty of the remote rural areas, where peasant farmers worked small plots of land owned by wealthy landlords. Later on his journey, Guevara was especially impressed by the camaraderie among those living in a Leper Colony, stating "The highest forms of human solidarity and loyalty arise among such lonely and desperate people." Guevara used notes taken during this trip to write an account entitled The Motorcycle Diaries, which later became a New York Times best-seller, and was adapted into a 2004 award-winning film of the same name. By trip's end, he came to view Latin America not as collection of separate nations, but as a single entity requiring a continent-wide liberation strategy. His conception of a borderless, united Hispanic America sharing a common 'Latino' heritage was a theme that prominently recurred during his later revolutionary activities. Upon returning to Argentina, he completed his studies and received his medical degree in June 1953, making him officially "Dr. Ernesto Guevara." Guevara later remarked that through his travels of Latin America, he came in "close contact with poverty, hunger and disease" along with the "inability to treat a child because of lack of money" and "stupefaction provoked by the continual hunger and punishment" that leads a father to "accept the loss of a son as an unimportant accident." It was these experiences which Guevara cites as convincing him that in order to "help these people", he needed to leave the realm of medicine, and consider the political arena of armed struggle.

On July 7, 1953, Guevara set out again, this time to Bolivia, Peru, Ecuador, Panama, Costa Rica, Nicaragua, Honduras and El Salvador. On December 10, 1953, before leaving for Guatemala, Guevara sent an update to his Aunt Beatriz from San José, Costa Rica. In the letter Guevara speaks of traversing through the "dominions" of the United Fruit Company, which convinced him "how terrible" the "Capitalist octopuses" were. This affirmed indignation carried the "head hunting tone" that he adopted in order to frighten his more Conservative relatives, and ends with Guevara swearing on an image of the then recently deceased Joseph Stalin, not to rest until these "octopuses have been vanquished." Later that month, Guevara arrived in Guatemala where President Jacobo Arbenz Guzmán headed a democratically elected government that, through land reform and other initiatives, was attempting to end the latifundia system. To accomplish this, President Arbenz had enacted a major land reform program, where all uncultivated portions of large land holdings were to be expropriated and redistributed to landless peasants. The biggest land owner, and one most affected by the reforms, was the United Fruit Company, from which the Arbenz government had already taken more than 225,000 uncultivated acres. Pleased with the road the nation was heading down, Guevara decided to settle down in Guatemala so as to "perfect himself and accomplish whatever may be necessary in order to become a true revolutionary." In Guatemala City, Guevara sought out Hilda Gadea Acosta, a Peruvian economist who was well-connected politically as a member of the left-leaning Alianza Popular Revolucionaria Americana (APRA, American Popular Revolutionary Alliance). She introduced Guevara to a number of high-level officials in the Arbenz government. Guevara then established contact with a group of Cuban exiles linked to Fidel Castro through the July 26, 1953 attack on the Moncada Barracks in Santiago de Cuba. During this period he acquired his famous nickname, due to his frequent use of the Argentine vocative interjection che, a slang casual speech filler used similarly to "eh" or "pal."

Guevara's attempts to obtain a medical internship were unsuccessful and his economic situation was often precarious. On May 15, 1954, a shipment of Škoda infantry and light artillery weapons was sent from Communist Czechoslovakia for the Arbenz Government and arrived in Puerto Barrios. As a result, the U.S. CIA sponsored an army which invaded the country and installed the right-wing dictatorship of Carlos Castillo Armas. Guevara was eager to fight on behalf of Arbenz and joined an armed militia organized by the Communist Youth for that purpose, but frustrated with the group's inaction, he soon returned to medical duties. Following the coup, he again volunteered to fight, but soon after, Arbenz took refuge in the Mexican Embassy and told his foreign supporters to leave the country. Guevara’s repeated calls to resist were noted by supporters of the coup, and he was marked for murder. After Hilda Gadea was arrested, Guevara sought protection inside the Argentine consulate, where he remained until he received a safe-conduct pass some weeks later and made his way to Mexico. He married Gadea in Mexico in September 1955. The overthrow of the Arbenz regime cemented Guevara's view of the United States as an imperialist power that would oppose and attempt to destroy any government that sought to redress the socioeconomic inequality endemic to Latin America and other developing countries. In speaking about the coup Guevara stated:

"The last Latin American revolutionary democracy – that of Jacobo Arbenz – failed as a result of the cold premeditated aggression carried out by the U.S.A. Its visible head was the Secretary of State John Foster Dulles, a man who, through a rare coincidence, was also a stockholder and attorney for the United Fruit Company."

Guevara's conviction that Marxism achieved through armed struggle and defended by an armed populace was the only way to rectify such conditions was thus strengthened. Gadea wrote later, "It was Guatemala which finally convinced him of the necessity for armed struggle and for taking the initiative against imperialism. By the time he left, he was sure of this."

Guevara arrived in Mexico City in early September 1954, and worked in the allergy section of the General Hospital. In addition he gave lectures on medicine at the National Autonomous University of Mexico and worked as a news photographer for Latina News Agency. His first wife Hilda notes in her memoir My Life with Che, that for a while, Guevara considered going to work as a doctor in Africa and that he continued to be deeply troubled by the poverty around him. In one instance, Hilda describes Guevara's obsession with an elderly washerwoman whom he was treating, remarking that he saw her as "representative of the most forgotten and exploited class." Hilda later found a poem that Che had dedicated to the old woman, containing "a promise to fight for a better world, for a better life for all the poor and exploited." During this time he renewed his friendship with Ñico López and the other Cuban exiles whom he had met in Guatemala. In June 1955, López introduced him to Raúl Castro who subsequently introduced him to his older brother, Fidel Castro, the revolutionary leader who had formed the 26th of July Movement and was now plotting to overthrow the dictatorship of Fulgencio Batista. During a long conversation with Castro on the night of their first meeting, Guevara concluded that the Cuban's cause was the one for which he had been searching and before daybreak he had signed up as a member of the 26J Movement. By this point in Guevara’s life, he deemed that U.S.-controlled conglomerates installed and supported repressive regimes around the world. In this vein, he considered Batista a "U.S. puppet whose strings needed cutting."

Although he planned to be the group's combat medic, Guevara participated in the military training with the members of the Movement. The key portion of training involved learning hit and run tactics of guerrilla warfare. Guevara and the others underwent arduous 15-hour marches over mountains, across rivers, and through the dense undergrowth, learning and perfecting the procedures of ambush and quick retreat. From the start Guevara was Alberto Bayo's "prize student" among those in training, scoring the highest on all of the tests given. At the end of the course, he was called "the best guerrilla of them all" by their instructor, Colonel Bayo.

The first step in Castro's revolutionary plan was an assault on Cuba from Mexico via the Granma, an old, leaky cabin cruiser. They set out for Cuba on November 25, 1956. Attacked by Batista's military soon after landing, many of the 82 men were either killed in the attack or executed upon capture; only 22 found each other afterwards. Guevara wrote that it was during this bloody confrontation that he laid down his medical supplies and picked up a box of ammunition dropped by a fleeing comrade, finalizing his symbolic transition from physician to combatant. Only a small band of revolutionaries survived to re-group as a bedraggled fighting force deep in the Sierra Maestra mountains, where they received support from the urban guerrilla network of Frank País, the 26th of July Movement, and local campesinos. With the group withdrawn to the Sierra, the world wondered whether Castro was alive or dead until early 1957 when the interview by Herbert Matthews appeared in The New York Times. The article presented a lasting, almost mythical image for Castro and the guerrillas. Guevara was not present for the interview, but in the coming months he began to realize the importance of the media in their struggle. Meanwhile, as supplies and morale diminished, and with an allergy to mosquito bites which resulted in agonizing walnut-sized cysts on his body, Guevara considered these "the most painful days of the war." As the war continued, Guevara became an integral part of the rebel army and "convinced Castro with competence, diplomacy and patience." Guevara set up factories to make grenades, built ovens to bake bread, taught new recruits about tactics, and organized schools to teach illiterate campesinos to read and write. Moreover, Guevara established health clinics, workshops to teach military tactics, and a newspaper to disseminate information. The man who three years later would be dubbed by Time Magazine: "Castro's brain", at this point was promoted by Fidel Castro to Comandante (commander) of a second army column. As the only other ranked Comandante besides Fidel Castro, Guevara was an extremely harsh disciplinarian who unhesitatingly shot defectors. Deserters were punished as traitors, and Guevara was known to send execution squads to hunt down those seeking to go AWOL. As a result, Guevara became feared for his brutality and ruthlessness. During the guerrilla campaign, Guevara was also responsible for the often summary execution of a number of men accused of being informers, deserters or spies.

In his diaries, Guevara described the first such execution of Eutimio Guerra, a peasant army guide who admitted treason when it was discovered he accepted the promise of ten thousand pesos for repeatedly giving away the rebel's position for attack by the Cuban air force. Such information also allowed Batista's army to burn the homes of rebel-friendly peasants. Upon Guerra's request that they "end his life quickly", Che stepped forward and shot him in the head, writing "The situation was uncomfortable for the people and for Eutimio so I ended the problem giving him a shot with a .32 pistol in the right side of the brain, with exit orifice in the right temporal [lobe]." His scientific notations and matter-of-fact description, suggested to one biographer a "remarkable detachment to violence" by that point in the war. Later, Guevara published a literary account of the incident entitled "Death of a Traitor", where he transfigured Eutimio's betrayal and pre-execution request that the revolution "take care of his children", into a "revolutionary parable about redemption through sacrifice." Although he maintained a demanding and harsh disposition, Guevara also viewed his role of commander as one of a teacher, entertaining his men during breaks between engagements with readings from the likes of Robert Louis Stevenson, Cervantes, and Spanish lyric poets. His commanding officer Fidel Castro has described Guevara as intelligent, daring, and an exemplary leader who "had great moral authority over his troops." Castro has further remarked that Guevara took too many risks, even having a "tendency toward foolhardiness." Guevara's teenage lieutenant, Joel Iglesias, recounts such actions in his diary, noting that Guevara's behavior in combat even brought admiration from the enemy. On one occasion Iglesias recounts the time he had been wounded in battle, stating "Che ran out to me, defying the bullets, threw me over his shoulder, and got me out of there. The guards didn't dare fire at him ... later they told me he made a great impression on them when they saw him run out with his pistol stuck in his belt, ignoring the danger, they didn't dare shoot."

Guevara was instrumental in creating the clandestine radio station Radio Rebelde in February 1958, which broadcast news to the Cuban people with statements by the 26th of July movement, and provided radiotelephone communication between the growing number of rebel columns across the island. Guevara had apparently been inspired to create the station by observing the effectiveness of CIA supplied radio in Guatemala in ousting the government of Jacobo Arbenz Guzmán.

In late July 1958, Guevara played a critical role in the Battle of Las Mercedes by using his column to halt a force of 1,500 men called up by Batista's General Cantillo in a plan to encircle and destroy Castro's forces. Years later, Major Larry Bockman of the United States Marine Corps would analyze and describe Che's tactical appreciation of this battle as "brilliant." During this time Guevara also became an "expert" at leading hit and run tactics against Batista’s army, and then fading back into the countryside before the army could counterattack. As the war extended, Guevara led a new column of fighters dispatched westward for the final push towards Havana. Travelling by foot, Guevara embarked on a difficult 7 week march only travelling at night to avoid ambush, and often not eating for several days. In the closing days of December 1958, Guevara’s task was to cut the island in half by taking Las Villas province. In a matter of days he executed a series of "brilliant tactical victories" that gave him control of all but the province’s capital city of Santa Clara. Guevara then directed his "suicide squad" in the attack on Santa Clara, that became the final decisive military victory of the revolution. In the six weeks leading up to the Battle of Santa Clara there were times when his men were completely surrounded, outgunned, and overrun. Che's eventual victory despite being outnumbered 10:1, remains in the view of some observers a "remarkable tour de force in modern warfare." Radio Rebelde broadcast the first reports that Guevara's column had taken Santa Clara on New Year's Eve 1958. This contradicted reports by the heavily controlled national news media, which had at one stage reported Guevara's death during the fighting. At 3 am on January 1, 1959, upon learning that his generals were negotiating a separate peace with Guevara, Fulgencio Batista boarded a plane in Havana and fled for the Dominican Republic, along with an amassed "fortune of more than $ 300,000,000 through graft and payoffs." The following day on January 2, Guevara entered Havana to take final control of the capitol. Fidel Castro however took 6 more days to arrive, as he stopped to rally support in several large cities on his way to rolling victoriously into Havana on January 8, 1959. In mid-January of 1959, Guevara went to live at a summer villa in Tarara to recover from a violent asthma attack. While there he started the Tarara Group, a group that debated and formed the new plans for Cuba's social, political, and economic development. In addition, Che began to write his book Guerrilla Warfare while resting at Tarara.

In February, the revolutionary government proclaimed Guevara "a Cuban citizen by birth" in recognition of his role in the triumph. When Hilda Gadea arrived in Cuba in late January, Guevara told her that he was involved with another woman, and the two agreed on a divorce, which was finalized on May 22. On June 2, 1959, he married Aleida March, a Cuban-born member of the 26th of July movement with whom he had been living since late 1958. Guevara returned to the seaside village of Tarara in June for his honeymoon with Aleida. Guevara had children from both his marriages, and one illegitimate child, as follows: With Hilda Gadea (married August 18, 1955; divorced May 22, 1959), Hilda Beatriz Guevara Gadea, born February 15, 1956 in Mexico City; died August 21, 1995 in Havana, Cuba; with Aleida March (married June 2, 1959), Aleida Guevara March, born November 24, 1960 in Havana, Cuba, Camilo Guevara March, born May 20, 1962 in Havana, Cuba, Celia Guevara March, born June 14, 1963 in Havana, Cuba, and Ernesto Guevara March, born February 24, 1965 in Havana, Cuba; and with Lilia Rosa López (extramarital), Omar Pérez, born March 19, 1964 in Havana, Cuba.

During the rebellion against Batista's dictatorship, the general command of the rebel army, led by Fidel Castro, introduced into the liberated territories the 19th century penal law commonly known as the Ley de la Sierra. This law included the death penalty for extremely serious crimes, whether perpetrated by the dictatorship or by supporters of the revolution. In 1959, the revolutionary government extended its application to the whole of the republic and to those it considered war criminals, captured and tried after the revolution. According to the Cuban Ministry of Justice, this latter extension was supported by the majority of the population, and followed the same procedure as those in the Nuremberg Trials held by the Allies after World War II. To implement a portion of this plan, Castro named Guevara commander of the La Cabaña Fortress prison, for a five-month tenure (January 2 through June 12, 1959). Guevara was charged with purging the Batista army and consolidating victory by exacting "revolutionary justice" against those considered to be traitors, chivatos (informants) or war criminals. Serving in the post as commander of La Cabaña, Guevara reviewed the appeals of those convicted during the revolutionary tribunal process. On some occasions the penalty delivered by the tribunal was death by firing squad. Raúl Gómez Treto, senior legal advisor to the Cuban Ministry of Justice, has argued that the death penalty was justified in order to prevent citizens themselves from taking justice into their own hands, as happened twenty years earlier in the anti-Machado rebellion. Biographers note that in January 1959, the Cuban public was in a "lynching mood", and point to a survey at the time showing 93% public approval for the tribunal process. With 20,000 Cubans estimated to have been killed at the hands of Batista's collaborators, and many of those sentenced to death accused of torture and physical atrocities, the newly empowered government carried out executions "without respect for due process." Although the exact numbers differ, it is estimated that several hundred people were executed during this time. Conflicting views exist of Guevara's delight towards the executions at La Cabaña. Some exiled opposition biographers report that he relished the rituals of the firing squad, and organized them with gusto. What is acknowledged by all sides is that Guevara had become a "hardened" man, who had no qualms about the death penalty or summary and collective trials. If the only way to "defend the revolution was to execute its enemies, he would not be swayed by humanitarian or political arguments." This is further confirmed by a February 5, 1959, letter to Luis Paredes López in Buenos Aires where Guevara states unequivocally "The executions by firing squads are not only a necessity for the people of Cuba, but also an imposition of the people."

Along with ensuring "revolutionary justice", the other key early platform of Guevara's was establishing agrarian land reform. Almost immediately after the success of the revolution on January 27, 1959, Che Guevara made one of his most significant speeches where he talked about "the social ideas of the rebel army." During this speech, he declared that the main concern of the new Cuban government was "the social justice that land redistribution brings about." A few months later on May 17, 1959, the Agrarian Reform Law called on and crafted by Che Guevara went into effect, limiting the size of all farms to 1,000 acres. Any holdings over these limits were expropriated by the government and either redistributed to peasants in 67 acre parcels or held as state run communes. The law also stipulated that sugar plantations could not be owned by foreigners.

On June 12, 1959, Castro sent Guevara out on a three-month tour of 14 countries, most of them Bandung Pact members in Africa and Asia. Sending Guevara from Havana allowed Castro to appear to be distancing himself from Che and his Marxist sympathies, that troubled both the United States and some of Castro's 26th of July Movement members. He spent 12 days in Japan (July 15–27), participating in negotiations aimed at expanding Cuba's trade relations with that nation. During this visit, Guevara secretly visited the city of Hiroshima, where the American military had detonated an atom-bomb 14 years earlier. Guevara was "really shocked" at what he witnessed and by his visit to a hospital where A-bomb survivors were being treated.

Upon returning to Cuba in September 1959, it was evident that Castro now had more political power. The government had begun land seizures included in the agrarian reform law, but was hedging on compensation offers to landowners, instead offering low interest "bonds", which put the U.S. on alert. At this point the affected wealthy cattlemen of Camagüey mounted a campaign against the land redistributions, and enlisted the newly disaffected rebel leader Huber Matos, who along with the anti-Communist wing of the 26th of July Movement, joined them in denouncing the "Communist encroachment." During this time Dominican dictator Rafael Trujillo was offering assistance to the "Anti-Communist Legion of the Caribbean" who was training in the Dominican Republic. This multi-national force composed mostly of Spaniards and Cubans, but also of Croatians, Germans, Greeks, and right-wing mercenaries, were plotting to topple Castro's new regime. Such threats were heightened when on March 4, 1960, two massive explosions ripped through the French freighter La Coubre, which was carrying Belgian munitions from the port of Antwerp, and docked in Havana Harbor. The blasts killed at least 76 people and injured several hundred, with Guevara personally providing first aid to some of the victims. Cuban leader Fidel Castro immediately accused the CIA of "an act of terrorism" and held a state funeral the following day for the victims of the blast. It was at the memorial service that Alberto Korda took the famous photograph of Guevara, now known as Guerrillero Heroico. These perceived threats prompted Castro to further eliminate "counter revolutionaries", and utilize Guevara to now drastically increase the speed of land reform. To implement this plan, a new government agency the National Institute of Agrarian Reform (INRA) was established to administer the new Agrarian Reform law, and quickly became the most important governing body in the nation with Guevara serving as its head as minister of industries. Under Guevara's command, INRA established its own 100,000 person militia, used first to help the government seize control of the expropriated land and supervise its distribution, and later to set up cooperative farms. The land confiscated included 480,000 acres owned by U.S. corporations. Months later, as retaliation, U.S President Dwight D. Eisenhower sharply reduced the import of Cuban sugar (Cuba’s main cash crop), thus leading Guevara on July 10, 1960, to address over 100,000 workers in front of the Presidential Palace at a rally called to denounce U.S. "economic aggression."

Along with land reform, one of the primary areas that Guevara stressed needed national improvement was in the area of literacy. Before 1959 the official literacy rate for Cuba was between 60-76 %, with educational access in rural areas and a lack of instructors the main determining factor. As a result, the Cuban government at Guevara's behest dubbed 1961 the "year of education", and sent "literacy brigades" out into the countryside to construct schools, train new educators, and teach the predominately illiterate Guajiros (peasants) to read and write. Unlike many of Guevara's later economic initiatives, this campaign was "a remarkable success." By the completion of the campaign, 707,212 adults were taught to read and write, raising the national literacy rate to 96 %.

Guevara then acquired the additional position of Finance Minister as President of the National Bank, which along with Minister of Industries, placed Che at the zenith of his power, as the "virtual czar" of the Cuban economy. As a consequence of his new position, it was now Guevara's duty to sign the Cuban currency, which per custom would bear his signature. However, instead of using his more dignified full name, he dismissively signed the bills solely "Che." It was through this symbolic act, which horrified many in the Cuban financial sector, that Guevara signaled his distaste for money and the class distinctions it brought about. Guevara's long time friend Ricardo Rojo later remarked that "the day he signed Che on the bills, (he) literally knocked the props from under the widespread belief that money was sacred." Guevara's first desired economic goal, which coincided with his aversion for wealth, was to see a nation-wide elimination of material incentives in favor of moral ones. He viewed capitalism as a "contest among wolves" where "one can only win at the cost of others," and thus desired to see the creation of a "new man and woman." Guevara continually stressed that a socialist economy in itself is not "worth the effort, sacrifice, and risks of war and destruction" if it ends up encouraging "greed and individual ambition at the expense collective spirit." A primary goal of Guevara's thus became to reform "individual consciousness" and values to produce better workers and citizens. In his view, Cuba's "new man" would be able to overcome the "egotism" and "selfishness" that he loathed and discerned was uniquely characteristic of individuals in capitalist societies. In describing this new method of "development", Guevara stated:

"There is a great difference between free-enterprise development and revolutionary development. In one of them, wealth is concentrated in the hands of a fortunate few, the friends of the government, the best wheeler-dealers. In the other, wealth is the people’s patrimony."

A further integral part of fostering a sense of "unity between the individual and the mass", Guevara believed, was volunteer work and will. To display this, Guevara "led by example", working "endlessly at his ministry job, in construction, and even cutting sugar cane" on his day off. He was known for working 36 hours at a stretch, calling meetings after midnight, and eating on the run. Such behavior was befitting of Guevara's new program of moral incentives, where each worker was now required to meet a quota and produce a certain number of goods. However, as a replacement for the pay increases abolished by Guevara, workers who now exceeded their quota only received a certificate of commendation, while workers who failed to meet their quotas were given a pay cut. Guevara unapologetically defended his personal philosophy towards motivation and work, stating:

"This is not a matter of how many pounds of meat one might be able to eat, or how many times a year someone can go to the beach, or how many ornaments from abroad one might be able to buy with his current salary. What really matters is that the individual feels more complete, with much more internal richness and much more responsibility."
