Cavite initially comprised a single district in 1898, when it elected four representatives to the Malolos Congress that lasted until 1899.
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.
Upon the restoration of the Philippine Commonwealth in 1945, the province and its two cities reverted to the pre-war lone district representation.
Cavite was reapportioned into three congressional districts under the new Constitution[2] which was proclaimed on February 11, 1987, and elected members to the restored House of Representatives starting that same year.
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[5] and third districts[6] of the province.
