Fidel Castro

Fidel Alejandro Castro Ruz (1926–2016) led the 26th of July Movement that overthrew the U.S.-backed government of Fulgencio Batista on 1 January 1959. He served as Prime Minister of Cuba from 1959 to 1976 and then as President of the Council of State and Council of Ministers from 1976 until he formally transferred power to his brother Raúl Castro in February 2008. He also held the post of First Secretary of the Communist Party of Cuba from its founding in 1965 until 2011.

Castro's tenure reshaped Cold War geopolitics in the Western Hemisphere. After the failed U.S.-sponsored Bay of Pigs invasion in April 1961, he publicly declared the Cuban Revolution to be socialist. The following year, the placement of Soviet ballistic missiles on the island triggered the Cuban Missile Crisis of October 1962, resolved through a U.S.–Soviet understanding that included the withdrawal of the missiles and, secretly, the removal of U.S. Jupiter missiles from Turkey.

Domestically, his government nationalised foreign-owned industries and large agricultural estates, expanded literacy and public health programmes, and suppressed political opposition and independent media. The United States imposed a comprehensive trade embargo, formalised in 1962 and tightened by the Cuban Democracy Act (1992) and the Helms–Burton Act (1996), which the UN General Assembly has voted to condemn annually since 1992.

Internationally, Castro projected influence well beyond Cuba's size. He dispatched Cuban troops to Angola (from 1975) and Ethiopia (from 1977), supported leftist movements across Latin America and Africa, and chaired the Non-Aligned Movement twice (1979–1983 and 2006–2009). For Model UN and IR researchers, Castro is a key case study in revolutionary state-building, asymmetric defiance of a superpower neighbour, and the durability of personalist socialist regimes. He died on 25 November 2016.
