It is originally occupied by the Aetas and later displaced by the Ilongot tribe because the Aetas are known of their nomadic characters. Many years later, permanent settlement were made by different civilized ethnic groups like Ilocanos, Tagalog and others in search of good fortune in this virgin land. As the population and settlement increases, regular barrios were created. These are the barrios of Zamora, Banuar, Burgos, Del Pilar, Dibibi, Eden, Villamor and five (5) more sitios of Villapeña, Villarose, Tucod, Calaocan and Dingasan at the municipality of Aglipay: barrios of San Marcos, Gundaway and portion of Mangandingay at the municipality of Diffun and the other part of Mangandingay at the municipality of Saguday. The above stated barrios of different municipalities became the territorial jurisdiction of Cabarroguis by virtue of Republic Act No. 5554 enacted by the Philippine Congress authored by then Honorable Senator Leonardo Perez on June 21, 1969.
