Quezon City (Tagalog: Lungsod Quezon, Tagalog pronunciation:[luŋˈsod ˈkɛːson]; Spanish: Ciudad Quezon [sjuˈðað ˈkeson]; also known as QC or Kyusi[3]) is the most populous city in the Philippines. It was founded by and named after Manuel L. Quezon, the 2nd President of the Philippines, to replace Manila as the national capital. The city was proclaimed as capital in 1948 and held the status until 1976 when the proclamation was reverted.[4]

In 1938, President Quezon created the People's Homesite Corporation and purchased 15.29km2 (6sqmi) from the vast Diliman Estate of the Tuason family; this piece of land became known then as Barrio Obrero ("Workers' Village"). The National Assembly of the Philippines passed Commonwealth Act 502, known as the Charter of Quezon City, originally proposed as "Balintawak City; Assemblymen Narciso Ramos and Ramon Mitra Sr. successfully lobbied the assembly to name the city after the incumbent president. President Quezon allowed the bill to lapse into law without his signature on October 12, 1939, thus establishing Quezon City.[5][6]

When Quezon City was created in 1939, the following barrios or sitios: Balingasa, Balintawak, Galas, Kaingin, Kangkong, La Loma, Malamig, Masambong, Matalahib, San Isidro, San Jose, Santol, and Tatalon from Caloocan; Cubao, the western half of Diliman, Kamuning, New Manila, Roxas and San Francisco del Monte from San Juan; Balara, Barangka, the eastern half of Diliman, Jesus de la Peña and Krus na Ligas from Marikina; Libis, Santolan and Ugong Norte from Pasig and some barrios from Montalban and San Mateo were to be given to the new capital city. Instead of opposing them, the six towns willingly gave land to Quezon City in the belief that it would benefit the country's new capital. However, in 1941, the area within Wack Wack Golf and Country Club was reverted to Mandaluyong, and Barangka and Jesus de la Peña to Marikina. In addition, the land of Camp Crame was originally part of San Juan.  On 1 January 1942, President Quezon issued an executive order from the tunnel of Corregidor designating Jorge Vargas Mayor of Greater Manila, a new political entity comprising, aside from Manila proper, Quezon City, Kalookan, Pasay, San Juan, Mandaluyong, Makati, and Parañaque.  Greater Manila would later be expanded to include Las Piñas, Malabon, and Navotas.
