Abraham Lincoln's Reconstruction plan, the Ten Percent Plan, required a small percentage of voters to swear allegiance to the U.S. and accept emancipation to rejoin the Union. In contrast, the tougher Wade-Davis Bill by Congress demanded harsher terms for re-admission. Lincoln's moderate approach aimed at restoring the Union quickly and was considered lenient by some in Congress.
Step-by-step explanation:
President Abraham Lincoln's plan for Reconstruction was known as the Ten Percent Plan.
The components of this plan included offering a general pardon to Southerners except for high-ranking Confederate leaders; requiring that 10% of the 1860 voting population in the former Confederate states to take an oath of future allegiance to the United States and accept emancipation; and drafting new state constitutions once these oaths were taken.
Meanwhile, the Wade-Davis Bill proposed by Congress required a stricter approach, including 50% of voters to declare loyalty, an "iron-clad" oath for voting in constitutional conventions, banning Confederates from the new government, and declaring Confederate debts null and void.
Lincoln believed that these states had never left the Union and that his moderate approach would encourage loyalty and shorten the war, despite disagreements with Radical Republicans who wanted more guarantees for the rights of freedpeople and viewed his approach as too lenient.
