Under the administration of President Benigno Aquino III, two deals were agreed upon between the national government and the MILF: the Framework Agreement on the Bangsamoro signed on October 15, 2012 and the Comprehensive Agreement on the Bangsamoro in March 27, 2014. which include plans regarding the establishing of a new autonomous region. In 2012, Aquino intended to establish a new autonomous political entity under the name "Bangsamoro" to replace the Autonomous Region in Muslim Mindanao which he called a "failed experiment." Under his administration, a draft for the Bangsamoro Basic Law (BBL) was made but failed to get traction to become law to the Mamasapano clash of January 2015 which involved the murder of 44 mostly-Christian Special Action Force (SAF) personnel by allegedly combined forces of the MILF and the Bangsamoro Islamic Freedom Fighters (BIFF) after an operation to kill Malaysian militant Zulkifli Abdhir known by the alias "Marwan". In 2018, a unification gathering of all the sultans of the Sulu archipelago and representatives from all ethnic communities in the Sulu archipelago (Basilan, Sulu, and Tawi-tawi) commenced in Zamboanga City, declaring themselves as the "Bangsa Sug" peoples and separating them from the "Bangsa Moro" peoples of mainland central Mindanao. They cited the complete difference in cultures and customary ways of life as the primary reason for their separation from the Muslims of mainland central Mindanao. They also called the government to establish a separate Philippine state, called "Bangsa Sug", from mainland Bangsa Moro or to incorporate the Sulu archipelago to whatever state is formed in the Zamboanga Peninsula, if ever federalism in the Philippines is approved in the coming years. Under the presidency of Aquino's successor, Rodrigo Duterte, a new draft for the BBL was made and became legislated into law as the Bangsamoro Organic Law (BOL) in 2018. A plebiscite was held on January 21, 2019 to ratify the BOL, with a majority of ARMM's voters deciding for the ratification of the law which meant that the future abolition of the ARMM and the establishment of the Bangsamoro Autonomous Region was in motion. Voters in Cotabato City voted to join the new autonomous region while Isabela City voted against inclusion. The Commission on Elections proclaimed that the BOL is "deemed ratified" on January 25, 2019.
