Region XI was originally called Southern Mindanao, and in addition to the three Davao provinces also included Surigao del Sur and South Cotabato. At that time, Compostela Valley was still part of Davao province. Republic Act No. 7225, ratified on March 16, 1992, created the province of Sarangani from South Cotabato. Then, Republic Act No. 7901, signed on February 3, 1995, by President Fidel V. Ramos moved Surigao del Sur into the newly created region of Caraga (Region XIII). Finally, on September 19, 2001, President Gloria Macapagal-Arroyo's Executive Order No. 36 reorganized the regions and provinces in Mindanao. This moved South Cotabato and Sarangani to SOCCSKSARGEN region and renamed Southern Mindanao as Davao Region.
