History.
In 1754, Governor-General Don Arandia sent Comandante Dovilla, who was based in Pangasinan, to establish a civil government and spread Christianity among the non-Christian Tribes. The mission first saw the Valley of Yapa (Yapa meaning bountiful) which was inhabited by the Allagots, the second descendants of the Bormangi and Owak, and the third descendants of the Kalanguya, Ibaloi, Ilo-o, and Karao tribes who settled in the fertile valley. When the comandante (commander) and his company arrived in the valley of Yapa, the villagers entertained them under a big tree called “Kalabao”, which stood in the middle of the valley. It was from these words “Kalabao” and “Yapa” where the present name “Kayapa” was coined.
On January 29, 1915, Governor-General Francis Burton Harrison signed and issued Executive Order No. 9, transferring all territories of the former Spanish Commandancia of Kayapa, except the area which lies within the Benguet watershed of the Agno River, from the sub-Province of Benguet to the Province of Nueva Vizcaya. On November 11, 1950, President Elpidio Quirino signed Executive Order No. 368, proclaiming the Municipality of Kayapa as a regular town, thus, merging Kayapa and Pingkian into one town as it is today.
