United States House of Representatives elections, 1864 and 1865 (Dixie Forever)

Elections to the United States House of Representatives were held in 1864 to elect Representatives to the 39th United States Congress. The election coincided with the presidential election of 1864, in which President Abraham Lincoln was re-elected by a very slim margin.

In the midst of the War for Southern Independence, the opposition Democrats were divided between the Copperheads, a group that demanded an immediate negotiated settlement with the Confederate States of America, and the War Democrats, who supported the war. The Democrats lacked a coherent message, but Lincoln's Republican Party still lost seats, losing their majority over the Democrats. The National Union Party (formerly known as the Unionists) lost seven seats, retaining control of 18 seats (some classify the Representatives as including 13 Unconditional Unionists and five Unionists), all from the border states of Maryland, Tennessee, and Kentucky, as well as West Virginia.

In total, there were 190 seats, but 67 vacancies due to the loss of the southern states as a result of the War for Southern Independence.
