1954 Guatemalan coup d'état
The 1954 Guatemalan coup d'état, code-named Operation PBSuccess, was a covert operation carried out by the U.S. Central Intelligence Agency (CIA) that deposed the democratically elected Guatemalan President Jacobo Árbenz and ended the Guatemalan Revolution of 1944–1954. It installed the military dictatorship of Carlos Castillo Armas, the first in a series of U.S.-backed authoritarian rulers in Guatemala.
