 Before Basilan was converted to a province, it had three regular municipalities, Isabela, Lamitan, and Maluso which were districts of the city of Basilan.Even when Col. Nanquil was appointed Military Governor, the city of Basilan was still functioning under Mayor Brown until December 31, 1975, due to its territorial boundary dispute with the Province of Basilan.The second military Governor was Rear Admiral Romulo M. Espaldon.
