Sept. 11, 1973 - The elected Marxist goverment of President Salvador Allende is ousted by the military, headed by the commander in chief of the Army, Gen. Augusto Pinochet. Allende is believed to have killed himself with a machine gun in the besieged presidential palace when it became evident his government was falling. According to official figures, 2,796 people die, 750 disappear, and thousands are jailed.
Dec. 17, 1974 - Pinochet assumes the office of president. Under his rule, congress is suspended under a state of siege. A crackdown on leftists and dissidents is launched, earning Pinochet’s government a worldwide reputation for human rights abuses.
Sept. 11, 1980 - Voters approve a constitution providing for a return to democracy after a minimum of eight years. The vote is marred by opposition charges of massive fraud.
