The group composed of Muslims who seek to establish a separate Mindanao is the MNLF (Moro National Liberation Front). The MNLF is a political organization in the Philippines that advocates for the self-determination of the Moro people in Mindanao. They aim to address the grievances of the Muslim population and work towards achieving autonomy or independence for Mindanao.
The MNLF has been actively involved in negotiations with the Philippine government to address the historical marginalization and discrimination faced by the Muslim communities in Mindanao. Through their efforts, they have aimed to secure a more inclusive and equitable society for the Moro people.
