How and when did military dictatorship end in Chile?

The military Dictatorship in Chile, led by General Augusto Pinochet, formally ended in 1990 after a national plebiscite held on October 5, 1988, where the Chilean people voted against extending Pinochet's rule. This led to a transition to democracy, culminating in the election of Patricio Aylwin as president in December 1989. The end of the dictatorship was marked by a gradual restoration of civil liberties and democratic institutions over the following years.
