Most of the Palawans are now settled in the highlands of the island of Palawan, from just north of Quezon on the west side and Abo-Abo on the east, all the way to the southern tip of the island at Buliluyan. Their religion is an old form of belief once practiced throughout the central Philippines prior to the Spanish arrival in the 16th century; a mix of traditional animism with elements of Hinduism and Islamic belief. Some have embraced Islam from their southern Molbog and Palawani neighbors. A small number of them are Protestant due to recent missionary campaigns.
