History

Early history

Pre-Hispanic settlement in the area can be dated to prehistoric times, as evidenced in the names of towns such as Pila, Laguna, whose name can be traced to the straight mounds of dirt that form the boundaries of the rice paddy, or Pilapil. The written history of the province of Laguna, (Lagoon in Spanish) and that of the Southern Tagalog region, dates to 900 AD. The Laguna Copperplate Inscription is the oldest known written document found in the Philippines. It notes that its subject was released from a debt to the Lord of Pailah Jayadewa.
