Long before the Christian settlers came, the land embracing the Celebes Sea, which was to become the town of Kiamba, was made-up of two settlements, Kraan settlements in the west, Kling Settlements in the east. Kraan was ruled by a chieftain Datu Budin, Kling by another Chieftain Datu Dani.
At about this time, the government sent survey teams to survey sites for the new towns envisioned to set up Mindanao as a vast undeveloped territory with a very rich natural resources waiting to be tapped. The government saw a land of promise in Mindanao. It embarked on all project to develop Mindanao by sending settlers to S outhernmost Island. Settlers started arriving in Kiamba in 1921.
Datu Dani and Datu Budin died in 1921. Datu Budin succeeded by his grandson, Datu Mangegkem and Datu Dani by his grandson Datu Obpon.
As the settlers grew in number, the government set up the constabulary to maintain peace and order. The first constabulary officer sent to Kiamba was Lt. Julian Esquejo, who established his quarters in Linek. He was the representative of Kiamba to the Provincial Government and serve the concurrently as the Deputy Governor. The constabulary in-charge of district received orders from the provincial government and transmitted to the National District President. In effect, the government was military, the municipal president as an agent of the office of the Constabulary Officer. Philippine Constabulary Commanders assigned to Kiamba at one time or another where; Lt. Macario Negrosa; Lt. Ernesto Vicente; and Lt. Climaco Pitoy.
At this time, Datu Pandita Madagpil was appointed Municipal District President with Datu Kamad Magunto as Municipal District Vice President. The appointment of Datu Madagpil united the two settlement of Kraan and Kling. Civilian officials replace the military and establish the civil government.

After years time, Datu Magunto was succeeded by Pascua Francisco, who remained Mayor up to the early part of the Japanese occupation until he went underground because the Imperial Army was hot in his pursuit, with Francisco in the underground, Thomas Falgui was appointed Mayor of Kiamba.
