The City of General Santos (known as Dadiangás, and abbreviated G.S.C. or GenSan.; Cebuano: Dakbayan sa General Santos) is the southernmost port city of the Philippines. Being a highly urbanized first class city, GenSan is one of the most populous urban centers in the country with a population of 538,086 as per census data of 2010. The city is bounded by municipalities of Sarangani Province namely Alabel in the East of the city, and Maasim in the South. The city is likewise bounded by South Cotabato municipality of Polomolok and Sarangani Province municipality of Malungon in the north, and the municipality of T'boli in the west of the city. General Santos City is the center of commerce, trade, and logistics of Region XII and the South Cotabato, Cotabato City, Sultan Kudarat, Sarangani Province and General Santos City (SOCCSKSARGEN) growth area.

Organized under the National Land Settlement Administration (NLSA) of the Commonwealth Government headed by President Manuel L. Quezon, General Paulino Santos led the relocation of 62 Christian settlers from Luzon to the shores of Sarangani Bay aboard the steam ship “Basilan” of Compania Maritima on February 27, 1939. The 62 pioneers (mostly agricultural and trade graduates) were the first big batch of settlers to land in GenSan with the mission to industriously cultivate GenSan's fertile expanse of land. After this first influx of pioneers, thousands more from Luzon and the Visayas have subsequently migrated into the area. This started the displacement of some native B'laan tribe to the mountains and lost their livelihood.
