Barrio Kabacan, renamed Barrio President Roxas that eventually became the seat of the municipal government was an insignificant area before 1951. In fact, it was Barrio Labuo, where the Manobo Chieftain, Datu Guabong Linog resided with his people who was thriving the area even before the outbreak of the World War II. The Manobo natives have learned to co- exist with the settlers from Visayas and Luzon. After the war, floods of emigrants from different parts of the country continued to arrive at a much faster rate so that by 1957, they had occupied almost all the vast fertile land of the Arakan plains. By this time settlers of Barrio President Roxas had bonded together into an organization called “La castellana home seekers Association” whose membership were mostly people from negros Occidental. This group helped enhanced the rapid development of the area outpacing the rest of the earlier settlements.
