Legislative districts of Cavite

Cavite initially comprised a single assembly district in 1907. 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 fifth senatorial district which elected two out of the 24-member senate.

In the disruption caused by the Second World War, two delegates represented the province 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. Cavite City, being a chartered city, was represented separately in this short-lived legislative body. Tagaytay, the province's other chartered city, was placed under provincial jurisdiction during the war and was not represented separately. Upon the restoration of the Philippine Commonwealth in 1945, the province and its two cities reverted to the pre-war lone district representation.

The province was represented in the Interim Batasang Pambansa as part of Region IV-A from 1978 to 1984, and returned three representatives, elected at large, to the Regular Batasang Pambansa in 1984. Cavite was reapportioned into three congressional districts under the new Constitution[1] which was proclaimed on February 11, 1987, and elected members to the restored House of Representatives starting that same year.

The passage of Republic Act No. 9727[2] on October 22, 2009 increased the number of the province's representatives from three to seven, starting in the 2010 elections. However, the conversion of Dasmariñas into a city has resulted in an additional legal name for the fourth district, which became the Lone District of Dasmariñas after the ratification of Republic Act No. 9723[3] on November 25, 2009.

Meanwhile, despite the conversion of Bacoor and Imus into cities in 2012, their charters explicitly indicate the retention of their numerical designations as the second[4] and third districts[5] of the province.

Republic Act No. 11069, signed into law on September 17, 2018, reapportioned Cavite into eight legislative districts — the most for any province — by creating a separate legislative district for the newly converted city of General Trias.[6] This effectively supersedes RA No. 9723 and confirms the sole legal designation of the congressional district of Dasmariñas as the fourth district of Cavite.
