Aleosan is located at the southeastern portion of Cotabato province, located almost midway between the cities of Davao and Cotabato at a distance of 110 and 120 km., respectively.

Aleosan was a barrio of Pikit before its creation as district political body. It was created as a regular municipality on August 18, 1947 by virtue of Executive Order No. 82 issued by then President of the Republic of the Philippines, Manuel A. Roxas.

Dating back decades before the outbreak of the Second World War, the golden history of what is known today as Aleosan has been alluded to the reign of the great Muslim leader – Datu Mantawil. This Datu ruled the area during the early American occupation. According to early settlers, the great Datu exuded a kind of democratic leadership that was enchanted by this reign when an adventurous young man, with a group of teachers, who finished schooling at the Agricultural College in Munoz, Nueva Ecija, came and settled within Mantawil’s sphere of influence. The leader of the group , Justino Doctolero, launched a massive educational drive that centered on health and literacy. By this, Doctolero was promoted to District Supervisor of the area which transcended up to Kidapawan. More significant, though was the love and admiration of the Datu and his people for the Christian settlers. For in those days, there existed an organization called “Alangkat” which resisted any attempt to educate inhabitants of the area. The group was said to be headed by a native named “Mampurok”.
