The Republic of Venezuela was a democratic republic first established in 1953, and replaced in 1999 by the Bolivarian Republic of Venezuela. Venezuela saw ten years of military dictatorship from 1948 to 1958. After the 1948 Venezuelan coup d'état brought an end to a three-year experiment in democracy, a triumvirate of military personnel controlled the government until 1952, when it held presidential elections. These were free enough to produce results unacceptable to the government, leading them to be falsified and to one of the three leaders, Marcos Pérez Jiménez, assuming the Presidency. His government was brought to an end by the 1958 Venezuelan coup d'état, which saw the advent of democracy with a transitional government under Admiral Wolfgang Larrazábal in place until the December 1958 elections. Prior to the elections, three of the main political parties, Acción Democrática, COPEI and Unión Republicana Democrática, with the notable exclusion of the Communist Party of Venezuela, signed up to the Puntofijo Pact power-sharing agreement.
