Fidel Castro: The Revolutionary of Cuba

Fidel Castro remains one of the most recognized political figures in world history. He led Cuba from 1959 to 2008 after spearheading the Cuban Revolution that overthrew dictator Fulgencio Batista. Under his leadership, Cuba transitioned into a socialist state, aligning with the Soviet Union during the Cold War. Despite facing global criticism and decades of U.S. sanctions, Castro’s rule defined Cuban politics and society for nearly five decades.

Kim Il-sung: The Eternal Leader of North Korea

Kim Il-sung established North Korea in 1948 and ruled until his death in 1994. He developed the country’s Juche ideology (self-reliance) and built one of the world’s most centralized regimes. His leadership laid the foundation for North Korea’s dynastic rule, which continues today under his grandson Kim Jong-un.

Ali Khamenei: The Supreme Leader of Iran

Ali Khamenei became Iran’s Supreme Leader in 1989, following the death of Ayatollah Ruhollah Khomeini.
