Which plan proposed a stricter requirement of 50% loyalty oath from voters in southern states?

The Wade-Davis Bill is recognized for its proposition of stringent requirements for Reconstruction in the South, particularly the demand that at least 50% of the white male citizens in a former Confederate state take an ironclad loyalty oath before that state could rejoin the Union. This condition was a significant departure from President Lincoln's more lenient approach outlined in his Proclamation of Amnesty and Reconstruction, which only required a 10% loyalty oath. The Wade-Davis Bill aimed to ensure that only those who were truly loyal to the Union would participate in the new state governments and emphasized a tougher stance on Southern integration and accountability after the Civil War.

In contrast to the Wade-Davis Bill, Johnson's Reconstruction Plan and Congressional Reconstruction proposed different strategies for reintegrating southern states. Johnson’s plan was relatively lenient, offering quick restoration to the Union without the strict loyalty requirement that the Wade-Davis Bill enforced. Congressional Reconstruction was characterized by a more punitive approach but did not specify a 50% loyalty oath as a condition. Thus, the Wade-Davis Bill stands out for its distinct and rigorous demand that reflected a more radical Republican vision for Reconstruction.
