Pre-colonial thalassocratic polity at Manila Bay, the largest pre-Spanish Philippine state, documented in Chinese records and the 900 CE Laguna Copperplate Inscription.
Sovereignty surrendered to Spain in 1571 CE following the Battle of Bangkusay Channel (3 June 1571), after which Lakandula's Tondo was integrated into the Spanish colonial system as a subordinate principalia community under the new capital Manila.
