Che Guevara in Guatemala
On July 7, 1953, Guevara set out again, this time to Bolivia, Peru, Ecuador, Panama, Costa Rica, Nicaragua, Honduras and El Salvador. In December 1953 he 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. Guevara decided to settle down in Guatemala so as to "perfect [him]self 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 American Popular Revolutionary Alliance (APRA). She introduced Guevara to a number of high-level officials in the Arbenz government. Guevara also 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 interjection "che", which is used in much the same way as "hey" 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, prompting a CIA-sponsored coup attempt. 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. 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.
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. This strengthened his conviction that Marxism achieved through armed struggle and defended by an armed populace was the only way to rectify such conditions.
Che Guevara - early years

Guevara learned chess from his father and began participating in local tournaments by the age of 12. During his adolescence and throughout his life he was passionate about poetry, especially that of Neruda, Keats, Machado, Lorca, Mistral, Vallejo, and Whitman. He could also recite Kipling's "If" and 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 Marx, Faulkner, Gide, and Verne. He also enjoyed reading Nehru, Kafka, Camus, Lenin, and Sartre; as well as France, Engels, Wells, and Frost.
As he got older he developed an interest in the Latin American writers Quiroga, Alegria, Icaza, Dario, and Asturias. Many of these author's ideas he would catalog 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 also fascinated him as he quoted him on a variety of topics from dreams and libido, to narcissism and the oedipus complex.
In 1948, Guevara entered the University of Buenos Aires to study medicine. While still a student in 1951, Guevara took a year off from his medical 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. 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.
Witnessing the widespread poverty, oppression and disenfranchisement throughout Latin America, and influenced by his readings of Marxist literature, Guevara began to view armed revolution as the solution to social inequality. By trip's end, he also viewed Latin America not as separate nations, but as a single entity requiring a continent-wide liberation strategy. His conception of a borderless, united Hispanic America sharing a common 'mestizo' Hispanic America was a theme that prominently recurred during his later revolutionary activities. Upon returning to Argentina, he completed his studies and received his medical diploma in June of 1953.
Che Guevara

As a young medical student, Guevara travelled 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, neo-colonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social reforms under President Jacobo Arbenz, whose eventual CIA-assisted overthrow solidified Guevara’s radical ideology.
Later, in Mexico, he met Fidel Castro and joined his 26th of July Movement. In December 1956, he was among the revolutionaries who invaded Cuba under Castro's leadership with the intention of overthrowing U.S.-backed Cuban dictator Fulgencio Batista. Guevara soon rose to prominence among the insurgents, was promoted to Comandante, and played a pivotal role in the successful guerrilla campaign that deposed Batista. Following the Cuban revolution, Guevara oversaw the revolutionary tribunals and executions of suspected war criminals from the previous regime. Later he served as minister of industry and president of the national bank, before traversing the globe as a diplomat to meet an array of world leaders on behalf of Cuban socialism. He was also a prolific writer and diarist, with one of his most influential works being a manual on the theory and practice of guerrilla warfare. Guevara left Cuba in 1965 to incite revolutions first in an unsuccessful attempt in Congo-Kinshasa and then in Bolivia, where he was captured with the help of the CIA and executed.
Both notorious for his harsh discipline and revered for his unwavering dedication to his revolutionary doctrines, Guevara remains an admired, controversial, and significant historical figure. As a result of his death and romantic visage, along with his invocation to armed class struggle and desire to create the consciousness of a "new man" driven by "moral" rather than "material" incentives; Guevara evolved into a quintessential icon of leftist inspired movements, as well as a global merchandising sensation. He has been mostly venerated and occasionally reviled in a multitude of biographies, memoirs, books, 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."
