The 1954 Guatemalan coup d'état was a covert operation carried out by the U.S.Central Intelligence Agency that deposed the democratically elected Guatemalan President Jacobo Árbenz and ended the Guatemalan Revolution of 1944–54. Code-named Operation PBSUCCESS, it installed the military dictatorship of Carlos Castillo Armas, the first in a series of U.S.-backed authoritarian rulers in Guatemala.[1]
