1990 Mindanao revolt

The 1990 Mindanao revolt was an uprising that occurred in parts of the island of Mindanao in the southern Philippines. It began when Alexander Noble, a dissident Philippine Army colonel linked to the 1989 Philippine coup attempt against President Corazon Aquino, and his supporters, which included Mindanaoan separatists, seized two military garrisons in Cagayan de Oro and Butuan without firing a shot and unilaterally proclaimed the independence of the Federal Republic of Mindanao on October 4, 1990, to be led by a civilian-military junta and with an ultimate goal of removing Aquino from office. However, Noble failed to gain support, and surrendered two days later following attacks by government forces. The revolt was the last overt attempt to overthrow Aquino's government until the end of her term in 1992.
