In the early efforts of Independence from American administration, Sergio Osmeña, Sr. the president of the first convention of provincial governors had joined those nationalists who petitioned Governor William Howard Taft to allow the formation of a political party advocating immediate independence for the Philippines in 1902. Sergio Osmeña, while a governor of Cebu, he was elected as the first Speaker of national assembly in 1907 and uses the venue to request further more Filipino control in the colony or “Filipinization” of the colony. From 1907 to 1916, the executive power of the Philippines was vested in an American Governor General, assisted by the departmental secretaries. Under the Osmeña Act, which passed by the Philippine Legislature a portion of this act “which provides the colonization to all parts of Mindanao that includes Jolo, Sulo and Basilan.” Hence, the distribution of land in Mindanao, program by the Bureau of Land “Free” otherwise known as “Homestead”, comprises twenty four (24) hectares track of agricultural land in addition to townsite lot of nine hundred twenty (920) square meters to give free and distributed to Filipino families from all walks of life from Luzon and Visayas willing to owned and occupy land in Mindanao. Hence, this was known as sakada people migrated to Mindanao by way of shipment from Luzon and other parts of the Visayas.

In 1912, arriving at the port of Surigao where the office of the bureau of land under American supervision. A noticed outside the office which read “Immediate Hiring of Workers” and willing to travel to all parts of Mindanao. Thus, Elpidio Empasis Barcelona, a very poor young Spanish Filipino mestizo hails from Tanke, Talisay in island of Cebu at the age of sixteen (16) became an employee of the Bureau of Land, under an American supervision in Land Survey Party. He works as a “transit man” and was designated as an assistant to the Engineering Land Surveyor due to his knowledge in mathematics. Experienced in surveying, his first assignment was from Butuan, Davao, and others parts of Cotabato, Pikit, Pagalungan, Midsayap as far as Zamboanga, Jolo, Sulo and Basilan. Also in 1912, back to area of Cotabato member of survey party led by an American geodetic engineer, continued their task of surveying, until they reached the most southern part of Cotabato, now called “GLAN”, which was then unexplored before. The existence of the biggest form of trees with approximate diameter of five to six feet, the least was four feet in diameter. There were very few existing houses of Blaans and Maguindanaons, who were native inhabitants in the area, numbered not more than seven houses or shanties near the banks of the river, and there were also others who lived in shanties at the hinterland. They found no Christians alike, the place was still unknown its name. A member of the survey party, approached a certain native Maguindanaon man who happened sharpening his long bladed bolo, and asked the native in Cebuano, “amigo, unsay nga’an ning dapita, ning lugaraha?” (Friend, what's the name of this area, this place?). The man did not actually understand Cebuano, as he thought the stranger was asking what he was doing he answered “GALANG” means sharpening in Maguindanaon. Then and there, the member of the survey party reported to Barcelona the name of the place is “Galang”. By mistake, it was named in the surveyed place and was established in the department of agriculture in a lot plan as “Colony No. 9- Glan”. The man was later known as Po Mangalaw.

Elpidio Empasis Barcelona made a written request to his American supervisor and recommended to the Bureau of Land Secretary to be reassigned in Cotabato colony no. 9 to assist SACADA people from Visayas in filing their free-patent application, relative to distribution and location of their homestead and also with corresponding lot number. Barcelona request's was granted. On ground that this new unexplored land (Colony No. 9) must be distributed to people Christians alike and also includes the native Blaans and Maguindanaons.

Barcelona wrote a letter to his families back in Carcar, Cebu, inviting them and their neighbors to come and the people from San Fernando, Naga, and other parts of Cebu joined in going to a place now called Glan. These people from Carcar and neighboring towns in Cebu decided themselves by majority to charter another ship, that directly to land at its seashores at the valley of Glan.

Heritage Town edit

The municipality is classified by members of the National Commission for Culture and the Arts as a heritage town. However, no ordinance or law has yet to be legislated for protection of Glan's heritage structures and colonial roads. A Vigan-type ordinance has been suggested by the Heritage Conservation Society, so that the town may be added to the Philippines UNESCO Tentative List in the future.

Barangays edit

Glan is politically subdivided into 31 barangays. Each barangay consists of puroks while some have sitios.
