Before its creation as a separate and independent Political Unit, Pigcawayan together with Alamada and Libungan were component barangays of
Midsayap. Pigcawayan, however at that time was more progressive than the two mentioned. How Pigcawayan got its name remains undocumented, however a version were given by the early settlers and passed from one generation to another. Herewith, the place now known as Pigcawayan was a battleground for the Iranuns and the Maguindanaons. Due to this fighting the inhabitants would abandon the place to be occupied by the victors. From this evolved the
Maguindanaon word "Pigawaan," which meant an abandoned place.
Partial inclusion to the Bangsamoro In 2019, twelve
barangays were among the 63 in
North Cotabato which became part of the
Special Geographic Area of the newly created
Bangsamoro, after having the affirmative vote won to join
the autonomous region in
a plebiscite held on February 6. Eight of them were among the 39 in the province that unsuccessfully voted
for the inclusion in the
Autonomous Region in Muslim Mindanao in 2001, while the other four were proposed to be part of the Bangsamoro, which replaced ARMM by virtue of
Republic Act No. 11054. In 2023, the
Bangsamoro Parliament approved the creation of eight new municipalities in the area. Those
barangays were organized into
Pahamuddin (
Bangsamoro Autonomy Act No. 41) following ratification in a plebiscite on April 13, 2024.
