The MILF is the vanguard of the Islamic movement in the Bangsamoro homeland in Mindanao and the neighbouring islands. The MILF was formed in 1977 when Hashim Salamat, supported by ethnic Maguindanaos from Mindanao, split from the Moro National Liberation Front, advocating a more moderate and conciliatory approach toward the government. In January 1987, the MNLF signed an agreement relinquishing its goal of independence for Muslim regions and accepting the government's offer of autonomy. The Moro Islamic Liberation Front, the next largest faction, refused to accept the accord and initiated a brief offensive that ended in a truce later that month. The Mindanao-based Moro Islamic Liberation Front fields around 2,900 troops.
