The 10% Plan, proposed by President Abraham Lincoln in 1863, aimed to facilitate the reintegration of Southern states into the Union after the Civil War.

Under this plan, a state could rejoin if 10% of its voters from the 1860 election took an oath of allegiance to the Union and accepted emancipation. This lenient approach sought to promote reconciliation and expedite the healing of the nation, but it faced criticism for being too forgiving toward former Confederates and sparked debate over Reconstruction policies.
