The 1812âÂÂ13 United States House of Representatives elections were held on various dates in various states between August 3, 1812, and April 30, 1813. Each state set its own date for its elections to the House of Representatives before the first session of the 13th United States Congress convened on May 24, 1813. They coincided with James Madison being re-elected president.
With the addition of the new state of Louisiana's at-large seat, along with the 39-seat gain as a result of the congressional reapportionment based on the 1810 United States census, the size of the House increased to 182 seats. Most relative population growth was in the West.
After America's entry into the War of 1812 against Britain, the Democratic-Republican and Federalist parties maintained pro-war and anti-war positions, respectively. Democratic-Republican representatives supported by voters in agrarian regions and Southern and Western states promoted war, asserting that Britain had violated American sovereignty and that despite Britain's strength, war was a manageable risk. Federalists and their supporters in New England and more densely populated Eastern districts opposed the war, citing likely damage to American trade and infrastructure.
This election saw significant voter support shift to the declining Federalists for the last time, almost entirely in New England, New York, and New Jersey. Despite this shift, Federalists did not approach national political recovery, House control, or meaningful policy influence.
Following the 1810 census, the House was reapportioned, adding 39 new seats.
There were special elections in 1812 and 1813 to the 12th United States Congress and 13th United States Congress.
Special elections are sorted by date then district.

Vermont gained two seats after the 1810 census. Rather than re-district, however, Vermont replaced its districts with a single at-large district. It would continue to use an at-large district in 1814, 1816, and 1818, then one more time in 1822 (with 5 seats).
Its elections were held September 1, 1812.

Virginia gained one seat after the 1810 census, bringing its representation in the House of Representatives to 23 seats, the largest number Virginia would ever have.

New York, with its 27 seats, surpassed Virginia and remained the most populous state until the late 1960s.
Its elections were held in April 1813, after the term began but before Congress's first meeting.
