Augusto Pinochet

A general in the Chilean army, Pinochet took power in a military coup in 1973. Under Pinochet, approximately 40,000 critics and suspected communists were imprisoned, tortured or killed. Besides political oppression, Pinochet introduced free-market reforms influenced by Milton Friedman. Facing international pressure and a lost referendum, Pinochet handed over power to his democratically elected successor in 1990. However, Pinochet maintained immunity from prosecution.
