The 1950s in the Dominican Republic were defined by the tightening grip and ultimate collapse of the Rafael Trujillo dictatorship (1930–1961).
Sugar, mining, and tourism drove GDP growth. Infrastructure expanded. But wealth concentrated in Trujillo's inner circle; rural and urban poor saw little benefit.
Trujillo's regime controlled press, unions, courts, and the military. The SIM (secret police) enforced loyalty through surveillance, torture, and assassination. Dissent was criminalized.
May 30, 1961: Trujillo assassinated on a highway outside Santo Domingo by dissident military officers. His death triggered a chaotic transition: brief democratic opening (Juan Bosch, 1963), military coup, U.S. intervention (1965), and eventual return to electoral democracy (1966 onward).
The 1950s were the dictatorship's peak—and its prelude to collapse.
