BRIEF HISTORICAL BACKGROUND
The municipality of Sultan Naga Dimaporo was formerly called “Karomatan,” derived from a Maranao word, “Kormatan,” which means a generous and reverent reception of guest. It was told that there was this place where Maruhombatua, an Islamic preacher and a descendant of an Arab missionary, was cordially received and afforded a formal welcome. To the Cebuanos, “karomatan” is a derivative of the word “Karomata” which means an animal drawn transport.
Karomatan, once a barangay of the municipality of Kapatagan, became a municipality in 1953 by virtue of Executive Order No. 588 dated April 10, 1953 issued by then President Elpidio Quirino. It was formally inaugurated on July 30, 1953. Hon. Macarimbang Pantaran became the first Municipal Mayor by appointment; elected Mayor in the 1955 election, and served as Mayor until 1967 through re-election.

- From Malabang: Bauyan, Dadoan, Calibao Payongan
The barrio/barangay of Karomatan was then made the Poblacion of this municipality.
In the 1967 elections, Hadji Mohammad Naga Dimaporo ran for Municipal Mayor unopposed. He ran for the second and third terms in 1971 and in 1986 still unopposed. He held the position until the 1986 EDSA revolution, where non-political figures were catapulted to power under the interim Officer-In-Charge (OIC) system. Four OIC Mayors were designated one after the other, namely: Lt. Col Celso Undag, Captain Faisal Umpa, Hadji Tumalding Calib, and lastly, Hadji Suwaib Enca. By the mandate of the 1987 Constitution, the first election was held in December 1987 where Hon. Motalib M. Dimaporo was overwhelmingly elected against Hadji Tumalding Calib. In the 1992 election, Mayor Motalib Dimaporo was reelected with a landslide margin over Hadji Tumalding Calib. In the 1995 local election, Mayor Motalib Dimaporo ran for the third time, this time unopposed.
Karomatan was renamed Sultan Naga Dimaporo in 1992 in honor of the late Mayor Sultan Naga Dimaporo. The municipality is composed of 37 barangays, the same number of barangays when it was first created in 1953.
Sultan Naga Dimaporo is currently under the administration of Mayor Ulwan Dimaporo with his father, Motalib Dimaporo, serving the as the Municipal Vice Mayor.
