The Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) is a special administrative region located in the southern part of the Philippines. Covering approximately 12,711 square kilometers, the territory spans the Mindanao mainland and the Sulu Archipelago. It is bordered by the Sulu Sea to the west, the Celebes Sea to the south, and the Moro Gulf at its center.
Administratively, Bangsamoro governs six primary provinces: Basilan, Lanao del Sur, Maguindanao del Norte, Maguindanao del Sur, Sulu, and Tawi-Tawi.
The seat of government and bureaucratic coordination for BARMM is located in Cotabato City. The city plays a vital role as an administrative hub, licensing center, and headquarters for regional ministries.
The jurisdiction of BARMM also includes a designated area known as the Special Geographic Area. The area consists of 63 villages in North Cotabato Province that voted to join Bangsamoro through a plebiscite in 2019. Transit between the mainland and island territories relies on maritime transport routes and inter-island feeder airlines.
Each province within the BARMM region maintains its local government units at the provincial, municipal, and city levels. The local administrative bodies handle daily governance under the coordination of the Bangsamoro Ministry of the Interior and Local Government.
According to 2020 Census data from the Philippine Statistics Authority, the Bangsamoro region is inhabited by approximately 4.4 million people. The majority of the population practices Islam, comprising several major ethnic groups such as the Maguindanao, Maranao, Tausug, Yakan, and Sama.
Although designated as a Muslim autonomous region, the area is also home to non-Muslim residents and indigenous communities, including the Teduray, Lambangian, and Dulangan Manobo tribes. The civil rights and cultural traditions of non-Muslim residents remain protected under regional laws.
Behind the Establishment of Autonomous Status
The establishment of BARMM was the culmination of a lengthy peace process between the Philippine Government and the Moro Islamic Liberation Front insurgent group. Both parties signed the Comprehensive Agreement on the Bangsamoro in 2014 to conclude decades of armed conflict in Mindanao.
To implement the agreement, the Philippine Congress drafted the Bangsamoro Organic Law, which was signed by President Rodrigo Duterte in 2018. The law officially took effect after the majority of southern residents voted in favor during a two-stage plebiscite in early 2019.
The official launch of BARMM replaced the former autonomous framework, the Autonomous Region in Muslim Mindanao. The previous ARMM structure was deemed ineffective because key political and budgetary decisions remained tightly controlled by the central government in Manila.
To manage administrative functions prior to local elections, transitional governance was assigned to the Bangsamoro Transition Authority. Representatives from both the MILF and the national government jointly led the interim body. Together, they drafted fundamental legal frameworks ranging from administrative governance to regional revenue generation.
The transitional process also encompassed the gradual decommissioning of MILF armed forces. A portion of former combatants was integrated into the Philippine National Police and the Armed Forces of the Philippines as a measure to stabilize security in the southern region.
Model of Autonomous Governance
BARMM operates under a parliamentary system led by an Autonomous Chief Minister. The executive head is elected directly by the 80 members of the Bangsamoro Parliament.
Members of the regional parliament represent various sectors, including local political parties, single-member parliamentary districts, and reserved sectoral slots for women, youth, and indigenous peoples.
To sustain administrative operations, BARMM receives a dedicated annual fiscal allocation known as the Block Grant. The central government automatically transfers 5 percent of total national internal revenue collections to support autonomous fiscal management.
In addition to its distinct governance structure, the region operates a Shari'ah Judicial System. The courts handle civil matters involving family law, marriage, and inheritance among Muslim residents. In practice, the Shari'ah courts operate parallel to the national judicial system under the supervision of the Supreme Court of the Philippines.
Despite internal administrative flexibility, the central government in Manila retains exclusive authority over strategic sectors. The national government maintains sole jurisdiction over matters pertaining to national sovereignty, including defense, foreign affairs, and monetary policy.
