Summary

From 1983 to 1986, a broad coalition of Filipinos, led by Corazon Aquino and opposition groups, campaigned to overthrow President Ferdinand Marcos. The movement was sparked by the assassination of Benigno Aquino and grew through mass protests, boycotts, and civil disobedience. The campaign succeeded in forcing Marcos into exile and installing Corazon Aquino as president.

Background

Ferdinand Marcos was elected president of the Philippines in 1965, but after being barred from a third term he declared martial law and assumed near absolute power. He dissolved congress, controlled the military, and arrested political opponents, including Senator Benigno Aquino. The goal of the campaign was to overthrow Marcos and, after the 1986 elections, install Corazon Aquino as president.
