In the disruption caused by the Second World War, two delegates represented the province of Tayabas in the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines.
Quezon (including the sub-province of Aurora) were represented in the Interim Batasang Pambansa as part of Region IV-A from 1978 to 1984.
It was during this period that Aurora was proclaimed as a regular province, on August 13, 1979, by virtue of Batas Pambansa Blg.
The province was guaranteed its own congressional district under the new Constitution[3] which was proclaimed on February 11, 1987, and elected its member to the restored House of Representatives starting that same year.
However, in 1935, all senatorial districts were abolished when a unicameral National Assembly was installed under a new constitution following the passage of the Tydings–McDuffie Act, which established the Commonwealth of the Philippines.
