Key moments in history that shaped the life of Che Guevara include his experiences during the Guatemalan coup of 1954, which radicalized him and underscored the impact of U.S. intervention in Latin America. His travels across South America exposed him to the harsh realities of poverty and inequality, fueling his commitment to revolution. Guevara became a key figure in the Cuban Revolution, advocating for armed struggle against imperialism. After the Cuban success, he sought to inspire revolutions elsewhere, ultimately ending his life in Bolivia while pursuing his vision of global socialism.
