Augusto José Ramón Pinochet Ugarte was a Chilean military officer who was the dictator of Chile from 1973 to 1990. From 1973 to 1981, he was the leader of the military junta, which in 1974 declared him President of the Republic and thus the dictator of Chile; in 1980, a referendum approved a new constitution confirming him in the office, after which he served as de jure president from 1981 to 1990. His time in office remains the longest of any Chilean ruler.
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 military coup, with the support of the United States, 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 Julio Ponce Lerou. The regime used censorship of entertainment as a way to reward supporters of the regime and punish opponents. These policies produced high economic growth and dramatically increased economic inequality. Departing from these policies, Pinochet's government also caused the 1982 monetary crisis, and thus produced its devastating effects on the Chilean economy. Pinochet's wealth grew considerably during his years in power through dozens of bank accounts secretly held abroad and holdings in real estate. He was later prosecuted for embezzlement, tax fraud, and kickbacks on arms deals.
Pinochet's 17-year rule was given a legal framework through a controversial 1980 plebiscite, which approved a new constitution drafted by a government-appointed commission. In a 1988 plebiscite, 56% voted against Pinochet's continuing as president, which led to democratic elections for the presidency and Congress. After stepping down in 1990, Pinochet continued to serve as Commander-in-Chief of the Chilean Army until 10 March 1998, when he retired and became a senator-for-life in accordance with his 1980 Constitution. However, while in London in 1998 Pinochet was arrested under an international arrest warrant in connection with numerous human rights violations. Following a legal battle, he was released on grounds of ill-health and returned to Chile on 3 March 2000. In 2004, Chilean Judge Juan Guzmán Tapia ruled that Pinochet was medically fit to stand trial and placed him under house arrest. By the time of his death on 10 December 2006, about 300 criminal charges were still pending against him in Chile for numerous human rights violations during his 17-year rule, as well as tax evasion and embezzlement during and after his rule. He was also accused of having corruptly amassed at least US$28 million.
