On July 23, 1979, President
Ferdinand Marcos signed Executive Order No. 549 creating the Office of the Commissioner for Islamic Affairs.
Rear Admiral Romulo Espaldon was appointed as commissioner and
Michael Mastura as deputy commissioner. On May 28, 1981, the Office of the Commissioner for Islamic Affairs was abolished and replaced with the Ministry of Muslim Affairs by virtue of Executive Order No. 697 with Espaldon as Minister and Mastura as Deputy Minister. Under his leadership, the Philippine Shari'ah Institute was launched and spearheaded the translation of the Code of Muslim Personal Laws from English to Arabic, and the first
Madrasa policy conference was held to discuss the integration of Madrasa-type education into the Philippine Educational System. Two months later, the Ministry was renamed Office of Muslim Affairs in order to minimize the number of ministries (25 at the time) and simplify the management of government. Other ministries that were reclassified as offices were the Ministry of Budget and Ministry of Public Information. On June 30, 1984, the Office of Muslim Affairs was merged with the Office of the Presidential Assistant on National Minorities (PANAMIN) to form the Office of Muslim Affairs and Cultural Communities (OMACC). It was first headed by Director General
Simeon Datumanong and later by Candu Muarip. On January 30, 1987, President
Corazon Aquino divided the OMACC into three distinct and separate offices: the Office for the Muslim Affairs (OMA), the Office for Northern Cultural Communities (ONCC), and the Office for Southern Cultural Communities (OSCC). The OMA was first headed by Executive Director Jiamil Dianalan and later by
Dimasangcay Pundato. On February 18, 2010, Congress enacted Republic Act No. 9997 which abolished the OMA and created the National Commission on Muslim Filipinos. It was first headed by Bai Omera Dianalan-Lucman. ==Major development programs==
