In 1973, Chile's Marxist government was overthrown by a dictatorial military regime led by Augusto Pinochet. With the goal of exterminating Marxism, Pinochet suspended parliament, banned political activity, limited civil liberties and boosted efforts to guard Chilean borders. Between 1973 and 1983, in an attempt to protect the country from its neighbors, Pinochet's government littered the Chilean borders of Bolivia, Peru and Argentina with 293 minefields containing one million mines. In 1990, Pinochet stepped down and a presidential parliamentary democracy was restored with the election of Patricio Aylwin.
