History Establishment of Metro Manila On November 7, 1975, President Ferdinand Marcos issued Presidential Decree No. 824 creating Metro Manila and its managing public corporation, the Metropolitan Manila Commission (MMC) after the residents of the affected cities and municipalities approved the creation of Metro Manila in a referendum held on February 27, 1975. The move consolidated the Philippine capital Manila and adjacent Quezon City with two cities and twelve municipalities of the province of Rizal and one municipality of the province of Bulacan into Metro Manila and designated Metro Manila as the capital of the Philippines. Marcos appointed his wife, First Lady Imelda Marcos, as governor and Ismael Mathay Jr. as vice governor. The office was located in front of the present-day GMA Network at EDSA corner Timog Avenue in Diliman, Quezon City. November 7, thus, is marked as the anniversary of both the region and the government body that supervises it, the MMDA. On May 29, 1976, President Ferdinand Marcos issued Presidential Decree No. 940, restoring the City of Manila as the capital city of the Philippines, and designating Metro Manila as the permanent seat of national government. The MMC became effectively defunct when on January 9, 1990, President Corazon Aquino issued Executive Order No. 392, in accordance to Article 18, Section 8 of the 1987 Philippine Constitution which replaced the commission with the Metropolitan Manila Authority (MMA).
