Sarangani: History
=== Early history ===
The earliest civilization in the province can be found in Maitum, Sarangani, where the Maitum Anthropomorphic Pottery or Maitum Jars were found. The jars have been dated to approximately 5 BC to 370 AD, one of the oldest in the entire Southeast Asian region and the Philippines. The discovery testified to the long history of cultural exchanges in Sarangani and its people.
The Sarangani was once part of Sultanate of Maguindanao. The establishment of the Sultanate in the area caused more Maguindanaon settlers arrival. After the fall of the Sultanate of Maguindanao as a great power in Mindanao, Datu Uto of Buayan expanded his domain towards Sarangani Bay. Sarangani would eventually be under the Sultanate of Buayan until the American era.
Sarangani Island (now part of Davao Occidental) was named Antonia by the Spanish explorer Ruy López de Villalobos in 1543, in honor of Antonio de Mendoza y Pacheco, the viceroy of New Spain who had appointed López de Villalobos to lead an expedition to the Western Islands (now the Philippines) because of their relation by marriage. The early inhabitants who first inhabited Sarangani were the indigenous natives, called MunaTo, a native term for "first people."
In 1942, the Japanese troops occupied Southern Cotabato. In 1945, Filipino troops of the 6th, 10th, 101st and 102nd Infantry Division of the Philippine Commonwealth Army and 10th Constabulary Regiment of the Philippine Constabulary entered in and liberated Southern Cotabato and fought against the Japanese Imperial Army forces during the Battle of Cotabato at the end of World War II under the Japanese Occupation.
Before its inception in 1992, Sarangani was part of South Cotabato under its third district. The province was created by Republic Act No. 7228 on March 16, 1992, penned by Congressman James Chiongbian, who would later become the province's first representative to the House of Representatives, ratified in a plebiscite on May 19, 1992 and installed its first set of officials on November 28, 1992. His wife, Priscilla Chiongbian, became the first Governor of Sarangani.
The Sangil people are active in the struggle for self-determination as part of their strategy to preserve and develop their culture and social institutions. The creation of Sarangani province itself was an effort to ease tensions between the Sangil people and the Philippine government.
