Quezon City is the former capital (1948–1976) and the most populous city in the Philippines. Located on the island of Luzon, Quezon City (popularly known to Filipinos as QC) is one of the cities and municipalities that make up Metro Manila, the National Capital Region. The city was named after Manuel L. Quezon, the former president of the Commonwealth of the Philippines who founded the city and developed it to replace Manila as the country's capital. Quezon City is not located in and should not be confused with Quezon province, which was also named after the president. Having been the former capital, many government offices are located in the city, including the Batasang Pambansa Complex, the seat of the House of Representatives, which is the lower chamber in the Philippine Congress. The main campuses of two noteworthy universities, the Ateneo de Manila University and the country's National University—the University of the Philippines Diliman—are located in the city.
