Brief Overview of Koronadal City
The settlement of Koronadal and its creation as a municipality by virtue of Executive Order No. 82 dated August 18, 1947 was marked by a rapid initial development. So that when the province of South Cotabato was created under Republic Act No. 4849 on July 18, 1966, it easily became the capital town.
In the past, the place was populated by B'laans and Maguindanaos. The word Koronadal is believed to have been derived from two Maguindanaoan word - Koron or Kolon meaning cogon grass and nadal or dalal meaning plain which aptly described the place to the natives. On the other hand, Marbel, which is another term for the poblacion, is a B'laan term Marb-El which means "murky waters". It is possible that the name was first used to refer to a river, now called Marbel River.
Koronadal used to comprise the area extending from the bank of Buluan Lake to the north to Barangay Polonoling in the municipality of Tupi to the south.; from Quezon mountain range to the northeast to the municipality of T'boli to the southeast.
Because the areas were unsettled, landless farmers from Luzon and Visayas were recruited by the government when the National Land Settlement Administration was created under Commonwealth Act No. 141. When the Marbel Settlement District was crated on January 10, 1940, Jesus Larrabaster was the appointed overseer of the area. The first settlers were distributed with either eight (8) or twelve (12) hectare lots.
The settlers who had increased in number because of the arrival of more settlers from Luzon and Visayas provinces cleared the area, built bunkhouses, and constructed roads. Before the break of World War II, Marbel Settlement District had a total of 846 settlers with their families and dependents.
