# 1862–63 United States House of Representatives elections

The 1862–63 United States House of Representatives elections were held on various dates in various states between June 2, 1862, and November 3, 1863, during the American Civil War and President Abraham Lincoln's first term. Each state set its own date for its elections to the House of Representatives before the first session of the 38th United States Congress convened on December 7, 1863. The congressional reapportionment based on the 1860 United States census was performed assuming the seceded states were still in the union, increasing the number of congressional districts to 241. West Virginia was given three seats from Virginia after the former broke away from the latter to rejoin the union as a separate state. The seceded states remained unrepresented and left 58 vacancies. Republicans lost 22 seats and the majority, while Democrats gained 28.
The Civil War to date had been only weakly successful for the Union, but had wrought major, disruptive change in the size and reach of the Federal Government, which before the war had been small and little seen beyond post offices, customs houses in ports, and scattered military posts. The Republican Party was also relatively new, yet had led the Union down a radical path of rapid industrialization and destructive total war.
Voters turned on the administration over its failure to deliver a swift victory over the Confederate rebellion (at times verging on military incompetence), along with rising inflation and new taxes to pay for the war effort, the suspension of habeas corpus, and the introduction of conscription.
Expressing a typical sentiment, the Cincinnati Gazette had editorialized that voters "are depressed by the interminable nature of this war, as so far conducted, and by the rapid exhaustion of the national resources without progress." Short of a majority, Republicans retained control with the support of the Unconditional Union Party. In September 1862, President Lincoln had warned the South that he planned by executive order, and as a war measure, to liberate all slaves in rebelling states as of January 1, 1863. The popularity of emancipation varied by region. It was more popular in New England and areas near the Great Lakes, and less popular in cities with large immigrant populations and in the southern portion of the North.
While Democrats hailed the elections as a repudiation of emancipation, the results did not alter Lincoln's plan or hamper prosecution of the war. In Lincoln's home district of Springfield, Illinois, John T. Stuart, a Democrat and one of Lincoln's former law partners, defeated the Republican incumbent. A fear of an influx of freed slaves competing for jobs and depressing wages, and a desire by white voters to prevent black suffrage, helped drive this result and others.
The sitting House Speaker, Galusha Grow of Pennsylvania, also lost re-election, but he would return to the House 30 years later in 1894. A Speaker of the House would not lose re-election again until 1994.

## Election summaries
