Augusto José Ramón Pinochet Ugarte (25 November 1915 – 10 December 2006) was a Chilean general and dictator who ruled Chile from 1973 to 1990, first as the leader of the Military Junta of Chile from 1973 to 1981, being declared President of the Republic by the junta in 1974 and becoming the de facto dictator of Chile, and from 1981 to 1990 as de jure president after a new constitution, which confirmed him in the office, was approved by a referendum in 1980. His rule remains the longest of any Chilean leader in history.
Augusto Pinochet rose through the ranks of the Chilean Army to become General Chief of Staff in early 1972 before being appointed its Commander-in-Chief on 23 August 1973 by President Salvador Allende. On 11 September 1973,
Pinochet seized power in Chile in a coup d'état, with the support of the US, that toppled Allende's democratically elected left-wing Unidad Popular government and ended civilian rule. In December 1974, the ruling military junta appointed Pinochet Supreme Head of the nation by joint decree, although without the support of one of the coup's instigators, Air Force General Gustavo Leigh. After his rise to power, Pinochet persecuted leftists, socialists, and political critics, resulting in the executions of 1,200 to 3,200 people, the internment of as many as 80,000 people, and the torture of tens of thousands. According to the Chilean government, the number of executions and forced disappearances was at least 3,095. Operation Condor, a U.S.-supported terror operation focusing on South America, was founded at the behest of the Pinochet regime in late November 1975, his 60th birthday.
Under the influence of the free market-oriented "Chicago Boys", Pinochet's military government implemented economic liberalization following neoliberalism, including currency stabilization, removed tariff protections for local industry, banned trade unions, and privatized social security and hundreds of state-owned enterprises. Some of the government properties were sold below market price to politically connected buyers, including Pinochet's son-in-law.
