When the Bangsamoro was created in 2019 to supplant the Autonomous Region in Muslim Mindanao, 63 barangays in the province of Cotabato were grouped with the newer autonomous region in the second part of the plebiscite held in February 6.

[2] By March 2020, these barangays were designated as a Special Geographic Area (SGA) of the Bangsamoro region.

[5] The town was initially proposed to be named as Malmar, but this was changed to Madridagao (and later Malidegao) to better reflect the area's culture and heritage.

Officers-in-charge (OIC) was selected by BARMM Chief Minister Murad Ebrahim to fill positions in the municipal government pending regular elections in 2025.

The municipality remains under the jurisdiction of the Special Geographic Area pending the creation of a new province.
