Background

Throughout the American Civil War, the Union army confronted the challenges of administering captured territory and establishing loyal civilian governments. Within the Union government and officer corps, there was disagreement over the legal nature and consequences of secession, the conditions for recognition of civilian governments, and the desirability or necessity of social reform in the South. In practice, President Abraham Lincoln and the Army implemented reconstruction policies which were deemed most conducive to military aims. Lincoln instituted a lenient " ten percent plan " in December 1863 and vetoed the more radical Wade–Davis Bill. For a time, Congress had seated members from the reconstructed governments of Virginia, Louisiana, and Tennessee, but this practice ended abruptly upon the start of the 38th Congress in December 1863.
