See also: Secession in the United States

The Confederacy fielded armies and sustained the rebellion into a second Congress, but the Union did not accept secession and secessionists were not eligible for Congress. Elections held in Missouri and Kentucky seated all members to the House and Senate for the 38th Congress. Elections held among Unionists in Virginia, Tennessee and Louisiana were marred by disruption resulting in turnouts that were so low compared with 1860, that Congress did not reseat the candidates with a majority of the votes cast.

• In rebellion 1862–64 according to the Emancipation Proclamation were Arkansas, Texas, Louisiana (parts), Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina and Virginia (parts). Tennessee was not held to be in rebellion as of the end of 1862.

Territory organized
