# 1812–13 United States House of Representatives elections

The 1812–13 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.

## New Jersey

New Jersey kept its delegation at six seats but changed from electing its Representatives on a statewide general ticket to using three plural districts of two seats each. These districts were used only for the 1812 election, and the state returned to using a single at-large district in 1814. This was only the second time that New Jersey used districts (the first being in 1798).
There was a statewide at-large election held in November 1812, that was invalidated:
   In October 1812, when the Federalists captured the State Legislature, both parties had already nominated their tickets for Presidential Electors and Congress. That election was scheduled for November 1812. However, … the Federalist[s], now controlling the legislature, changed the method of selecting Presidential Electors, from popular vote, to a choice by the Legislature and as a result the election for Presidential Electors was invalidated. In addition to changing the method of choosing Presidential electors, the Federalist also decided to alter the election of congressmen from state wide At-Large to Districts. The scheduled November elections were postponed and three separate Districts were created, each electing two Congressmen. This election was held January 12th and 13th 1813. Some towns, either because word of these changes did not reach them in time, or most likely in defiance, went ahead and held elections. The Republican ticket received almost all of the votes cast, with the Federalist getting only a single votes in two towns, which suggests they were protesting the changes made by the Legislature. These returns were never reported in the newspapers.

## New York

Ten seats were added after the 1810 census, bringing New York's representation to 27, the largest of any state at the time. New York would remain the state with the most members until surpassed by California in the 1970 census. There were two separate House of Representatives elections in 1812. The first was held in April 1812 for an un-reapportioned 17 representatives. This election was subsequently declared void and a new election was held on December 15–17, 1812, in which only three incumbents ran and two of whom were re-elected. New York thereby lost 4 Democratic-Republicans and gained 14 Federalists.

## Ohio

The 1810 census revealed dramatic population growth in Ohio since 1800, resulting in its representation increasing from a single Representative to six, resulting in the State being broken up into 6 districts, abolishing the at-large district. Jeremiah Morrow (Democratic-Republican), who had served since Ohio achieved statehood in 1803, retired to run for U.S. Senator, so that all six seats were open. Its elections were held October 13, 1812.
