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. Formed as a polity occupying several barangays, it was one of several polities on the Pasig River just prior to the Spanish colonization of the Philippines, alongside Tondo, Maynila, and Cainta. Archeological findings in Santa Ana have produced the oldest evidence of continuous habitation among the Pasig River polities, pre-dating artifacts found within the historical sites of Maynila and Tondo.
