In 1917 the undivided Mountain Province, of which Ifugao was a component sub-province, was provided representation in the Philippine Legislature. Pursuant to the Revised Administrative Code (Act No. 2711) enacted on March 10, 1917, the non-Christian-majority areas of the Philippines, which then included the Mountain Province, were to be collectively represented in the legislature's upper house by two senators from the 12th senatorial district, both appointed by the Governor-General.[1] Three assembly members, also appointed by the Governor-General, were to represent the Mountain Province and the chartered city of Baguio in the lower house as a single at-large district.[1]
The residents of Ifugao and the rest of the Mountain Province only began electing representatives through popular vote in 1935 by virtue of Act No. 4203; the law provided the territorial coverage for each lower house representative district, while also abolishing the senatorial district system.[2] The sub-province was then represented as part of the Mountain Province's third district.[2]
The enactment of Republic Act No. 4695 on June 18, 1966 made the sub-province of Ifugao into a full-fledged province.[3] The new province began electing its separate representative starting in the next general election.
