1812 and 1813 United States House of Representatives elections
The 1812 and 1813 United States House of Representatives elections were held at various dates in different states between April 1812 and August 1813 as James Madison was re-elected president. Following the 1810 Census, Congress added 39 seats to the House. 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. Election summaries.
