Established in 1984, the Moro Islamic Liberation Front (MILF) is a breakaway group of the Moro National Liberation Front (MNLF). The MILF rejects the peace pact the MNLF signed with the Government of the Republic of the Philippines (GRP) on September 2, 1996. Specifically, the MILF considers the political autonomy granted to the Moro people under the 1996 GRP-MNLF Final Peace Agreement as inadequate and unresponsive to the root causes of the conflict. Thus, even as Manila was negotiating with the MNLF, the MILF quietly built up its armed forces and mass base of supporters.
