A historical province known as Manila encompassed territories once held by various pre-Hispanic polities. This included the well-known Pasig River delta settlements of Maynila and Tondo, but smaller settlements such as those at Tambobong, Taguig, Pateros, and the fortified polity of Cainta. It became the capital of the colonial Philippines, with Manila (Intramuros) serving as the center of colonial power. In 1898, it included the city of Manila and 23 other municipalities. Mariquina also served as the capital from 1898 to 1899, just as when the sovereignty of the Philippines was transferred to the United States. The province was dissolved and most of it was incorporated into the newly created province of Rizal in 1901.
