According to oral folk history, the native Abaknon people of the island of Capul were originally from the island of
Balabac, off the southern coast of
Palawan. They were originally a
Sama-Bajau group. In the 1300s, their island was annexed by the
Sultanate of Sulu. The people who refused to submit to the Sultanate and convert to
Islam fled Balabac under the leadership of a
datu named Abak. They sailed northwards until reaching the island of Capul. Here, they established a settlement which they called Abak. By 1610, Spanish
Jesuits arrived in the island and construction of the first church began around this period. The
Inabaknon language of the Abaknon people are still classified by linguists as a
Sama-Bajaw language, though the Abaknon people have converted to Christianity and have become culturally
Visayan due to proximity with Visayan groups. On June 18, 1966, barrios Mahaba, Maragat, Mongolbongol, Panganoron, Sila, Ternate, and Sang-putan were excised from Capul to form the new municipality of
San Vicente. ==Geography==
