Fidel Castro’s life was profoundly shaped by the Cuban Revolution, which he led. The revolution, beginning in 1953, was a response to the oppressive regime of Fulgencio Batista. Castro's early experiences as a political activist fueled his desire for social change and propelled him into leadership. Once in power, he transformed Cuba into a one-party socialist state, reflecting his commitment to Marxism and anti-imperialism. The revolution marked not only the beginning of his political career but also solidified his legacy as a revolutionary leader, impacting international relations and Cold War politics significantly.
