Kalinga-Apayao

Kalinga-Apayao used to be a province of the Philippines in the Cordillera Administrative Region in Luzon. It was split into the two provinces of Kalinga and Apayao with the passage of Philippine Republic Act No. 7878 on February 14, 1995. This RA amended the earlier Republic Act No. 4695, passed on June 18, 1966, which formed the provinces of Kalinga-Apayao, Benguet, Ifugao, and Mountain Province, from the earlier Mountain Province. See the History section of Mountain Province for details.
