Ernesto "Che" Guevara (May 14, 1928 - October 9, 1967), commonly known as Che Guevara, El Che, or simply Che, was an Argentine Marxist revolutionary, politician, author, military theorist, physician, and guerrilla leader. His stylized image also later became a countercultural symbol worldwide.
 
 As a young medical student, Guevara travelled through 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 inequalities were a result of capitalism, neo-colonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social revolution under President Jacobo Arbenz Guzmán, whose eventual CIA-assisted overthrow solidified Guevara’s radical ideology.
 
 Later, in Mexico, he joined and was promoted to commander in Fidel Castro’s 26th of July Movement, playing a pivotal role in the successful guerrilla campaign to overthrow the U.S.-backed Cuban dictator Fulgencio Batista. After the Cuban revolution, Guevara served in many prominent governmental positions, including President of the National Bank and “supreme prosecutor” over the revolutionary tribunals and executions of suspected war criminals from the previous regime. Along with traveling to meet world leaders on behalf of Cuban socialism, he was a prolific writer and diarist: his published work includes 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 help of the CIA and executed.
 
 Both notorious for his harsh discipline and revered for his unwavering dedication to his revolutionary doctrines, Guevara remains a controversial and significant historical figure. Because of his death, romantic visage, invocation to armed class struggle, and desire to create the consciousness of a "new man"; Guevara became an icon of leftist revolutionary movements worldwide, as well as a global merchandising sensation. He has been venerated and reviled in dozens of biographies, memoirs, books, essays, documentaries, songs, and films. Time Magazine declared him one of the 100 most influential people of the 20th century, while an Alberto Korda photograph of him entitled Guerrillero Heroico (shown), has been declared "the most famous photograph in the world."
