The Lumad are a group of Austronesian indigenous peoples in the southern Philippines. It is a Cebuano term meaning "native" or "indigenous". The term is short for Katawhang Lumad, the autonym officially adopted by the delegates of the Lumad Mindanao Peoples Federation (LMPF) founding assembly on 26 June 1986 at the Guadalupe Formation Center, Balindog, Kidapawan, Cotabato, Philippines. Usage of the term was accepted in Philippine jurisprudence when President Corazon Aquino signed into law Republic Act 6734, where the word was used in Art. XIII sec. 8(2) to distinguish Lumad ethnic communities from the islands of Mindanao.

The Autonomous Region in Muslim Mindanao was an autonomous region of the Philippines, located in the Mindanao island group of the Philippines, that consisted of five predominantly Muslim provinces: Basilan, Lanao del Sur, Maguindanao, Sulu, and Tawi-Tawi. It was the only region that had its own government. The region's de facto seat of government was Cotabato City, although this self-governing city was outside its jurisdiction.
