Note 2 — Chapter I · History of Magindanao

The term Mindanao2 or Magindanao was originally given to the town now known as Cotabato and its immediate vicinity. As the power of the sultan of Magindanao extended over the adjacent territory it was next applied to the lower Rio Grande Valley and later to all the valley and the whole seacoast that was brought under the rule of the sultan. The word is derived from the root “danao,” which means inundation by a river, lake, or sea. The derivative “Mindanao” means “inundated” or “that which is inundated.” “Magindanao” means “that which has inundation.” This is the most appropriate term which could have been given to this land. For more than 10 miles from the sea the Rio Grande, aided by the rise of the tide, periodically overflows its banks and floods all the adjacent lands. In the rainy season this inundation extends farther up and includes an extensive tract of country. The word “Cotabato” is in Moro kuta watu, which means a stone fort. Batu is the equivalent of watu in Malay, Sulu, Tagalog, and Visaya. This name is very modern, for the older maps that are still in use give the name Mindanao in place of Cotabato. The little stream that rises in the sulphur springs of Cotabato and empties into the Rio Grande at its junction with the Matampay in front of the present guardhouse is still known as the Stream of Magindanao.
