# Kasibu

Kasibu, officially the Municipality of Kasibu (Gaddang: Ili na Kasibu; Ilocano: Ili ti Kasibu; Tagalog: Bayan ng Kasibu), is a municipality in the province of Nueva Vizcaya, Philippines. According to the 2020 census, it has a population of 41,776 people.
Kasibu in the Ilongot language means, "a venue where people settle their differences."

## History

Long before the creation of the municipal district of Kasibu, there was a school and a constabulary detachment for the Ilongots, which necessitated the establishment of a government in the area. For this reason, the provincial board during Governor Alfonso Castañeda's time requested the Governor-General to authorize the establishment of this place as a provisional municipal district to be supervised and administered by the provincial board through the office of the provincial governor.
By virtue of Executive Order No. 59, signed on January 1, 1926, by Governor General Leonard Wood, Kasibu was established as part of the Municipal District of Bambang. However, by virtue of a Proclamation issued by Governor Leon Cabarroguis in 1933, Kasibu was reorganized as a separate Municipal District. On November 9, 1950, Executive Order No. 368, signed by President Elpidio Quirino, abolished the municipal district structure in government and reattached Kasibu to Bambang. The very low population caused the abolition, as residents started to evacuate and abandon Kasibu due to the presence of dissidents from 1950 to 1955. On January 9, 1956, when peace and order was restored, President Ramon Magsaysay issued Executive Order No. 160 creating Kasibu as a separate municipality, but losing territorial jurisdiction over some of its barrios specifically Payupay, Belance, Oyao, Teguep, Manacgoc, Pangancan and Munguia, all on the eastern side in favor of Dupax del Norte.
