Cordillera Administrative Region
administrative region of the Philippines

The Cordillera Administrative Region (CAR; Ilocano: Rehion/Deppaar Administratibo ti Kordiliera; Filipino: Rehiyong Administratibo ng Cordillera), also known as the Cordillera Region and Cordillera (IPA: [kɔrdiljɛra]), is an administrative region in the Philippines, situated within the island of Luzon. It is the only landlocked region in the archipelago, bordered by the Ilocos Region to the west and southwest, and by the Cagayan Valley Region to the north, east, and southeast.
The region comprises six provinces: Abra, Apayao, Benguet, Ifugao, Kalinga and Mountain Province. The regional center is the highly urbanized city of Baguio, which is the largest city in the region.
The region was officially created on July 15, 1987, covering most of the Cordillera Mountain Range of Luzon that is home to numerous ethnic groups. Nueva Vizcaya province has a majority Igorot population transplanted by the American colonial government in the Cagayan Valley Region instead during the early 20th century, as does Quirino.
According to the 2020 Census of Population and Housing, this region is the least populated region in the Philippines, less than that of the national capital, the City of Manila.
History
Spanish colonial era
During the Spanish occupation of the Philippines, Christianization and eventual subjugation of the mountain region proved difficult for the Spanish colonial government. Several comandancias were established by the Spanish colonial government in strategic areas of the mountain region. Among them were Amburayan, Cabugaoan, Kayapa, Quiangan, Itaves, Apayaos, Lepanto, Benguet, Bontoc, Banaue, and Tiagan.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q13606. Authority coordinates are 17.167, 121.167. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1987 and 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
