The 1824–25 United States House of Representatives elections were held on various dates in various states between July 7, 1824 and August 30, 1825. Each state set its own date for its elections to the House of Representatives before the first session of the 19th United States Congress convened on December 5, 1825. Elections were held for all 213 seats, representing 24 states. They coincided with the contentious 1824 presidential election. After no presidential candidate won an electoral majority, in February 1825 the House of the outgoing 18th Congress chose the President, John Quincy Adams, in a contingent election. The approach of the 1824 presidential election ended the virtually nonpartisan Era of Good Feelings and motivated major realignment. The weak Federalist Party collapsed and the Democratic-Republican Party abruptly, catastrophically split. Though Andrew Jackson lost the contingent election, public attitudes toward the charismatic, famous Jackson mainly determined the new alignment. Partisans of Jackson often were called Jacksonians, by 1828 adopting the Democratic Party label. Opponents of Jackson often were called Anti-Jacksonians, coalescing under the leadership of newly elected President John Quincy Adams and soon forming the National Republican Party. Though both parties were new, and were not continuations of old parties, Jacksonians were more similar to the former Democratic-Republicans, while National Republicans were more similar to the former Federalists and also were political ancestors to the future Whig Party. Leadership of the National Republicans in opposition to Jackson later would transition to Henry Clay, whose support of Adams determined the contingent election. Election summaries Representatives regrouped into Jackson supporters and Adams supporters (comprising the Adams-Clay faction in the contingent election), while supporters of William Crawford, whose ill health and retirement had indirectly helped trigger the realignment, divided between the two factions with 33 going to the Adams-Clay faction and 22 going to the Jackson faction.
