Manila, also known as Tondo until 1859, was a province of the Philippines that encompassed the former pre-Hispanic polities of Tondo, Maynila, and Namayan. In 1898, it comprised the city of Manila and 23 other municipalities. In 1901, the province was dissolved, with the city of Manila absorbing six of its smaller neighboring municipalities. The remaining part was merged with the adjacent district of Morong to form the province of Rizal.
