The history of the Philippines between 900 and 1565 begins with the creation of the Laguna Copperplate Inscription in 900 and ends with Spanish colonisation in 1565. The inscription records its date of creation in the year 822 of the Hindu Saka calendar, corresponding to 900 AD in the Gregorian system. Therefore, the recovery of this document marks the end of prehistory of the Philippines at 900 AD. During this historical time period, the Philippine archipelago was home to numerous kingdoms and sultanates and was a part of the theorised Indosphere and Sinosphere.
