Chile transitioned back to democracy in 1990 after 17 years of authoritarian military rule led by General Augusto Pinochet. While Pinochet successfully implemented free market economic reforms, he failed to displace Chile's democratic political traditions and parties. Pinochet was forced to end his plans for lifelong rule after losing a 1988 plebiscite. Chile's transition to democracy faced challenges as it had to accept the authoritarian-created constitution, but over time civilian elites modified the institutions to establish a fully democratic system.
