The Nineteenth United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1825, to March 4, 1827, during the first two years of the administration of U.S. President John Quincy Adams. The apportionment of seats in the House of Representatives was based on the Fourth Census of the United States in 1820. The Senate had a majority of Jackson Men, while the House had an Anti-Jackson (pro-Adams) majority.
The Twenty-first United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1829, to March 4, 1831, during the first two years of Andrew Jackson's presidency. The apportionment of seats in the House of Representatives was based on the Fourth Census of the United States in 1820. Both chambers had a Jacksonian majority.
In the United States House of Representatives elections in 1828, the Jacksonians soundly took control of the presidency, with Andrew Jackson's victory, and greatly increased their majority in Congress. Outgoing President John Quincy Adams's unpopularity played a major role in the Jacksonian pick-up, as did the perception of the Anti-Jacksonian Party as urban and elitist. Major increases in suffrage also heightened Jacksonian wins, as newly enfranchised voters tended to associate with Jacksonian principles. The Anti-Masonic Party, a single issue faction based on distrust of Freemasonry, became the first third party in American history to garner seats in the House.

While the Democrats cultivated strong local organizations, the National Republicans relied on a clear national platform of high tariffs and internal improvements. Political scientists such as V.O. Key, Jr. consider this election to be a realigning election, while political scientists such as James Reichley instead see the election as a continuation of the Democratic-Republican tradition.
