Fidel Castro is known for his role in the Cuban Revolution, which successfully overthrew the U.S.-backed dictator Fulgencio Batista in 1959. Castro, along with comrades like Che Guevara, led a guerrilla warfare campaign that garnered significant popular support, advocating for social reforms and the redistribution of wealth. After seizing power, Castro established a socialist state in Cuba, aligning the country with the Soviet Union during the Cold War. His policies and leadership dramatically reshaped Cuba’s economy and society, leaving a complex and polarizing legacy that continues to influence discussions about socialism and governance in Latin America.
