The oldest civilization in the region is located in
Maitum, Sarangani, where the
Maitum Anthropomorphic Pottery were found. The jars have been declared as National Cultural Treasures, and are subject to the high protections ensured by Philippine and international laws. From around 14th century until the early 20th century, the Muslim sultanates of
Maguindanao and
Buayan dominated the large parts of Soccsksargen region, influencing the local datus in the area as well as having General Santos City under their direct control as a port.
Central Mindanao The region used to be named
Central Mindanao. Prior to the creation of the
Autonomous Region in Muslim Mindanao (ARMM), it comprised the following provinces: •
Maguindanao •
North Cotabato •
Sultan Kudarat •
Lanao del Norte •
Lanao del Sur With the creation of ARMM, Lanao del Sur, Maguindanao (excluding
Cotabato City), and Sultan Kudarat were removed from the region, leaving Lanao del Norte and Cotabato, and
Iligan,
Marawi and
Cotabato City as constituent provinces and cities. while Marawi became part of the ARMM. On December 18, 1998, Sultan Kudarat was transferred back to Central Mindanao through Republic Act No. 8744.
Soccsksargen In September 2001,
Executive Order No. 36 was signed by President
Gloria Macapagal Arroyo transferring
South Cotabato,
Sarangani,
General Santos (also known as the
SocSarGen District), from
Southern Mindanao to Region XII, and renaming the region, from
Central Mindanao, to
Soccsksargen.
Koronadal as new regional center By virtue of Executive Order No. 304 signed by then President
Gloria Macapagal Arroyo,
Koronadal was named as the regional political and socio-economic center of Soccsksargen on March 30, 2004. Regional departments, bureaus and offices were ordered to move from
Cotabato City, the former regional center of the region.
Special Cotabato barangays and Cotabato City exit Traditionally resisting efforts for inclusion to the Autonomous Region in Muslim Mindanao despite serving as the government center of the ARMM, the
January 21, 2019 Bangsamoro Autonomous Region creation plebiscite resulted in the surprise ratification of the Bangsamoro Organic Law in Cotabato City. This means the city may now formally serve as the capital of the region and the offices of the former ARMM will be retained for use by the
Bangsamoro Regional Government and now formally no longer constitutes part of the Soccsksargen Region. In addition to Cotabato City,
63 barangays in Cotabato province opted to join Bangsamoro, thus exiting the region as well. ==Demographics==
