Batanes initially had two representatives, one elected and one appointed, to the Malolos Congress in 1898; this remained so until 1899. It was later annexed to Cagayan as a sub-province, by virtue of Philippine Commission Act No. 209 on August 22, 1901, and was represented as part of the first district of Cagayan in the 1st Philippine Legislature starting in 1907. Upon its re-establishment as a regular province on May 20, 1909 by virtue of Act No. 1952, Batanes was granted separate representation, and elected one representative later that year.
When seats for the upper house of the Philippine Legislature were elected from territory-based districts between 1916 and 1935, the province formed part of the first senatorial district which elected two out of the 24-member senate.
Batanes retained its lone congressional district under the new Constitution[1] which was proclaimed on February 11, 1987, and elected its member to the restored House of Representatives starting that same year.
