Bohol island, Philippines
Created by virtue of Act 2711 of March 10, 1917, this island province of Bohol is the tenth largest island in the country. This oval-shaped province is located in the central portion of the Visayas lying between Cebu to the northwest and Leyte to the northeast. To its south is the big island of Mindanao which is separated from Bohol by the wide Mindanao Sea. Aside from the mainland, Bohol has 73 smalleroffshoreislandsandislets. Bohol is about 700 kilo- meters directly south of Manila and is about 70 kilometers southeast of Mactan Island.
The people of Bohol are said to be the descendants of the last group of inhabitants who settled in the Philippines called PINTADOS (the tattooed ones). Before the Spaniards came in 1521, Boholanos had already a culture of their own as evidenced by the artifacts dug at Mansasa, Tagbilaran, and in Dauis and Panglao using designs during the Ming Dynasty (960-1279). They had already a system of writing but most of the materials used were perishable like leaves and bamboo barks. They spoke a language similar to that of the nearby provinces.
The name Bohol is thought to be derived from the name of the barrio of Bo-ol, a barangay found in Tagbilaran City which was among the first places toured by the Magellan expedition. History has it that one of the Spanish ships of Magellan (the Concepcion) was burned in this province after Magellan was killed by Lapu-lapu in Mactan. In 1565, Miguel Lopez de Legazpi anchored in Jagna, one of the eastern municipalities of Bohol. He made a blood compact with Chiefs Sikatuna and Sigala in a small village near the present capital of the province, Tagbilaran City, signifying they were blood brothers. The province became a Jesuit mission in 1595. At this time, Bohol was a part of the province of Cebu and and was called a residencia. It became a separate politico-military province on July 22, 1854, together with the island province of Siquijor. In 1879, there were 34 towns belonging to the province with a total population of 253,103.
Two significant revolts were recorded during the Spanish regime. The Tamblot Uprising in 1621 led by a native priest or Babaylan, and the Dagohoy Rebellion from 1744 to 1829 led by Francisco Dagohoy which is consid- ered as the longest revolt recorded in the annals of Philippine history. American forces seized the province in March 17,1900.
Bohol is the home province of the fourth President of the Republic of the Philippines, CARLOS POLISTICO GARCIA (1957-1960) who was born in the municipality of Talibon.
Bohol must have been developed from the magmatic tectonic mechanism which resulted from the under- thrusting of the southwest Philippine Plate east of Samar and Surigao. The Alicia Schist, the oldest known rock formation in the island, is inferred to be part of the Bohol crustal rocks before plate interactions. All the succeeding igneous extrusive and intrusive events in Bohol are the results of these resurging interactions. Ongoing erosion, transport and sedimentation continue to accumulate marine and terrestrial deposits in the Bohol basin.
