The Augustinians built Pasig City in 1572 making it one of the oldest towns in the Philippines. But after the Government combined Pasig with Rizal making Pasig the capital of Rizal province in June 1901. It became the provincial capital, not until Metro Manila is formed in 1975 by the Metro Manila Commission making Pasig a city. Soon the government considered Pasig as a highly urbanized city. President Fidel V. Ramos signed it to become a law after five months on December 8, 1994. Pasig residents approved this through a referendum on January 21, 1995.
