# 1818–19 United States House of Representatives elections

The 1818–19 United States House of Representatives elections were held on various dates in various states between April 26, 1818, and August 12, 1819. Each state set its own date for its elections to the House of Representatives before the first session of the 16th United States Congress convened on December 6, 1819. They occurred during President James Monroe's first term. Also, newly admitted Alabama elected its first representatives in September 1819, increasing the size of the House to 186 seats.
This election occurred in a politically uneventful period marked by exceptionally low levels of partisan rivalry known as the Era of Good Feelings. The weak Federalist Party, with limited influence in few states, no longer effectively opposed the Democratic-Republican Party, which increased its large majority.

## Election summaries

Illinois was admitted in 1818, adding one seat.
Alabama and Maine were admitted during the 16th Congress. One new seat was added for Alabama, while Maine, splitting from Massachusetts, simply retained its Representatives.

## New York

New York elected its members April 28–30, 1818, the earliest of any state.
At this time, the Democratic-Republicans in New York were divided into two factions, the "Bucktails" who were opposed to Governor Dewitt Clinton's Erie Canal project, led by Martin Van Buren, and on the other side, Clinton's supporters, known as Clintonians. In many districts, the remaining Federalists allied with the Clintonians, with candidates running on a joint ticket. Several candidates who ran under that joint ticket cannot be clearly categorized, and are marked C/F. Others who ran under the joint ticket are marked by their party with a footnote indicating that they ran under the joint ticket.
