Democratic Action (, AD) is a Venezuelan social democratic and centre-left political party established in 1941. The party played an important role in the early years of Venezuelan democracy, leading the government during Venezuela's first democratic period (1945–1948). A decade of dictatorship under Marcos Pérez Jiménez followed, which saw AD excluded from power. With the advent of democracy in 1958, four Presidents of Venezuela came from Acción Democrática from the 1950s to the 1990s during the two-party period with COPEI. In the 2015 legislative elections held on 6 December, AD backed the opposition electoral alliance Democratic Unity Roundtable (MUD) which managed to grasp a supermajority. AD won 26 constituency representatives out of 167 seats in the unicameral National Assembly, making it the second-largest party in opposition to Nicolás Maduro. In July 2018, AD left the Democratic Unity Roundtable opposition coalition. The current General Secretary Of Democratic Action is Henry Ramos Allup. History Early years: 1931—1958 The party had a chaotic early history. The Agrupación Revolucionaria de Izquierda (ARDI) was founded in 1931 in Colombia by Rómulo Betancourt and other exile Venezuelans. In 1936 this became the Movimiento de Organización Venezolana (ORVE), which was then dissolved into the Partido Democrático Nacional (PDN). Finally, in 1941, after Isaías Medina Angarita legalized all political parties in Venezuela, Acción Democrática was founded by Betancourt and others. These included Rómulo Gallegos, Andrés Eloy Blanco, Luis Beltrán Prieto, Juan Oropeza, Luis Lander, Raúl Ramos Jiménez, Medardo Medina Febres, Enrique H. Marín, Rafael Padrón, Fernando Peñalver, Luis Augusto Dubuc, César Hernández, José V. Hernández and Ricardo Montilla. Gallegos was a highly prestigious writer, author of the iconic novel, Doña Bárbara (1929), while Eloy Blanco was a celebrated Venezuelan poet and witty humorist. After the October 1945 revolution, Betancourt was President of Venezuela until Rómulo Gallegos won the 1947 election (generally believed to be the first free and fair elections in Venezuelan history). Gallegos governed until being overthrown in the 1948 Venezuelan coup d'état. The 1945–48 period is known as the trienio. Many of AD's founders and early members went into exile during the subsequent dictatorship of Marcos Pérez Jiménez, and returned for the restoration of democracy in 1958. Political dominance: 1958—1999 After the restoration of democracy, AD joined the 1958 Puntofijo Pact, initiating a forty-year period of two-party dominance by AD and COPEI. Betancourt won the 1958 election, and Raúl Leoni won the following 1963 elections. AD
