The ten percent plan, formally the Proclamation of Amnesty and Reconstruction (13 Stat. 737), was a United States presidential proclamation and executive order issued on December 8, 1863, by President Abraham Lincoln, during the American Civil War. By this point in the war (nearly three years in), the Union Army had pushed the Confederate Army out of several regions of the South, and some rebellious states were ready to have their governments rebuilt. Lincoln's plan established a process through this postwar reconstruction could come about.
A component of President Lincoln's preliminary plans for the postwar reconstruction of the South, this proclamation decreed that a state in rebellion against the U.S. federal government could be reintegrated into the Union when 10% of the 1860 vote count from that state had taken an oath of allegiance to the U.S. and pledged to abide by Emancipation. Voters could then elect delegates to draft revised state constitutions and establish new state governments. All southerners except for high-ranking Confederate army officers and government officials would be granted a full pardon. Lincoln guaranteed southerners that he would protect their private property, though not their slaves. By 1864, Louisiana, Tennessee, and Arkansas had established fully functioning unionist governments.
This policy was meant to shorten the war by offering a moderate peace plan. It was also intended to further his emancipation policy by insisting that the new governments abolished slavery.
Congress reacted sharply to this proclamation of Lincoln's plan. Most moderate Republicans in Congress supported the president's proposal for Reconstruction because they wanted to bring a swift end to the war, but other Republicans feared that the planter aristocracy would be restored and the blacks would be forced back into slavery. Lincoln's reconstructive policy toward the South was lenient because he wanted to popularize his Emancipation Proclamation. Lincoln feared that compelling enforcement of the proclamation could lead to the defeat of the Republican Party in the election of 1864, and that popular Democrats could overturn his proclamation.
