Politician and revolutionary Che Guevara was born on June 14, 1928, in Rosario, Argentina. He died on October 9, 1967. His real name was Ernesto Rafael Guevara de la Serna. "Che" is a Spanish word spoken in Argentina, Uruguay, and Paraguay, and is used casually as a greeting, meaning "hey," "hey," or even a friendly "friend." Born into a wealthy family in Argentina, he aspired to become a doctor, but at the age of 23, a trip across South America with a friend on a dilapidated motorcycle changed his life. Witnessing the disparity between rich and poor, discrimination, and other injustices, Guevara became interested in Marxism. He then traveled to Mexico and met Fidel Castro, the Cuban rebel leader who was in exile. Impressed by Castro's way of life, Guevara decided to help Castro as a military doctor. He boarded a smuggling ship bound for Cuba, and after landing, despite losing many of his comrades, he rose to lead guerrilla activities to overthrow the Cuban dictatorship. In 1959, the Cuban Revolution was accomplished, and Guevara became president of the new Cuban government's National Bank.

He then left Cuba and worked as a revolutionary in Congo and Bolivia, but in 1967 he was captured and executed by government soldiers in Bolivia.

His ideas and way of life were enthusiastically supported by those with anti-American views and those aiming for revolution, and Guevara's portrait was printed on T-shirts and posters, becoming a symbol. Designs featuring his face are often seen in Japan as well.
