Kiliman

Kiliman was the earlier name of the people who established Buayan in Mindanao’s upper Cotabato valley. Local genealogies placed its foundation in the mid-fourteenth century; its chiefs bore the title rajah.

Datu Mamu expanded his power through marriages with neighboring chiefdoms. After Rajah Baguinda Ali preached Islam, Buayan became a sultanate and rivaled downriver Maguindanao. Rajah Silongan repulsed a combined Maguindanao and Spanish army in 1596, then joined a raid on Cebu and Panay in 1599. Buayan remained independent during the Spanish-Moro wars.
