The military dictatorship of Chile was an authoritarian military government that ruled Chile between 1973 and 1990. The dictatorship was established after the democratically elected government of Salvador Allende was overthrown by a CIA-backed coup d'état on 11 September 1973. The dictatorship was headed by a military junta presided by General Augusto Pinochet. The perceived breakdown of democracy and the economic crisis that took place during Allende's presidency were justifications used by the military to seize power. The dictatorship presented its mission as a "national reconstruction".
