Historical Trajectory
Phase I: Rise
Cuba declared independence from Spain in 1898, but U.S. military occupation delayed full sovereignty until 1902. The republic was established on 20 May 1902 under significant American influence, institutionalised through the Platt Amendment embedded in both Cuban and U.S. law. This amendment granted the United States the right to intervene in Cuban affairs and imposed restrictions on Cuba's independent foreign relations, rendering the new state effectively a U.S. client.
Phase II: Zenith
The republic experienced periods of relative economic growth tied closely to the U.S. sugar market, with Cuba supplying a guaranteed share of American sugar demand. The 1940 Constitution, considered one of the more progressive documents in Latin American history at the time, established civil liberties and social rights. Havana developed into a cosmopolitan capital with notable cultural output, while the sugar industry and U.S. investment shaped the broader economy.
Phase III: Decline
Persistent political instability, corruption, and authoritarian rule—most notably under Fulgencio Batista—eroded public confidence in the republic's institutions. Social inequality and U.S. economic dominance fuelled growing opposition. A revolutionary movement led by Fidel Castro launched armed resistance in the mid-1950s. On 1 January 1959, Batista fled the country, ending the republican period and beginning the Cuban Revolution, which fundamentally transformed the island's political and economic order.
