The region was established in 1975 through Presidential Decree No. 824 in response to the needs to sustain the growing population and for the creation for the center of political power and the seat of the Government of the Philippines. The Province of Manila, the predecessor entity of the region, is one of the first eight provinces that revolted against the Spanish colonial rule in the Philippines at the end of the 19th century. Manila's role in the Revolution is honored in the Flag of the Philippines, where the sun's eight rays symbolize the eight revolutionary provinces.
