Kabacan
Kabacan lies in the Cotabato basin of central Mindanao, where the Kabacan River joins the Pulangi. These waterways run through a broad lowland surrounded by uplands and form part of the great river system that drains toward the west coast. The basin was home to diverse communities, including the Maguindanao, whose rulers developed a sultanate linked by trade and religion to other parts of the southern Philippines and the Malay world.
