History.
By virtue of Executive Order No. 59, signed on 1 January 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, the Municipal District of Kasibu was reorganized as a Municipal District. On 9 November 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 9 January 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.
Barangays.
Kasibu is politically subdivided into 30 barangays.
