Namayan
Namayan (Baybayin: Pre-Kudlit: ᜈᜋᜌ or ᜐᜉ (Sapa), Post-Kudlit: ᜈᜋᜌᜈ᜔), also called Sapa and sometimes Lamayan, was an independent polity on the banks of the Pasig River in the Philippines. It is believed to have peaked in the 11th-14th centuries, although it continued to be inhabited until the arrival of European colonizers in the 1570s.
