be pivotal for Venezuela and transformed the basis of its economy from a heavy dependence on agricultural exports. It prompted an economic boom that lasted into the 1980s; by 1935, Venezuela's per capita gross domestic product was Latin America's highest. Gómez benefited handsomely from this, as corruption thrived, but at the same time, the new source of income helped him centralize the Venezuelan state and develop its authority. He remained the most powerful man in Venezuela until his death in 1935, although at times he ceded the presidency to others. The gomecista dictatorship (1935–1945) system largely continued under Eleazar López Contreras, but from 1941, under Isaías Medina Angarita, was relaxed. Angarita granted a range of reforms, including the legalization of all political parties. After World War II, immigration from Southern Europe (mainly from Spain, Italy, Portugal, and France) and poorer Latin American countries markedly diversified Venezuelan society. In 1945, a civilian-military coup overthrew Medina Angarita and ushered in a three-year period of democratic rule (1945–1948) under the mass membership party Democratic Action, initially under Rómulo Betancourt, until Rómulo Gallegos won the 1947 Venezuelan presidential election (generally believed to be the first free and fair elections in Venezuela). Gallegos governed until overthrown by a military junta led by the triumvirate , Marcos Pérez Jiménez, and Gallegos' Defense Minister, Carlos Delgado Chalbaud, in the 1948 Venezuelan coup d'état. The most powerful man in the military junta (1948–1958) was Pérez Jiménez (though Chalbaud was its titular president) and was suspected of being behind the death in office of Chalbaud, who died in a bungled kidnapping in 1950. When the junta unexpectedly lost the election it held in 1952, it ignored the results and Pérez Jiménez was installed as president, where he remained until 1958. The military dictator Pérez Jiménez was forced out on 23 January 1958. In an effort to consolidate a young democracy, the three major political parties (Acción Democrática (AD), COPEI and Unión Republicana Democrática (URD), with the notable exception of the Communist Party of Venezuela), signed the Puntofijo Pact power-sharing agreement. The two first parties would dominate the political landscape for four decades. During the presidencies of Rómulo Betancourt (1959–1964, his second term) and Raúl Leoni (1964–1969) in the 1960s, substantial guerilla movements occurred, including the Armed Forces of National Liberation and the Revolutionary Left Movement, which had split from AD in 1960. Most of these movements laid down their
