Final answer:
The main issue dividing Republicans during Reconstruction was how to reintegrate the Confederate states and manage freedmen's rights, with disputes between lenient reunification favored by President Andrew Johnson and more stringent measures proposed by Congressional Republicans. To mitigate conflict, a balanced plan upholding both reconciliation and protection of rights, with broad support, could have been pursued.
Step-by-step explanation:
The main issue relating to Reconstruction that divided Republicans at the end of the Civil War was how to reintegrate the Confederate states into the Union and how to manage the rights of the freedmen. The split was largely between President Andrew Johnson, who favored a lenient, quick reunification that largely ignored the rights of former slaves, and the Congressional Republicans, who sought a more punitive approach towards the South and stronger protections for freedmen. Radical Republicans wanted to punish the former slaveholders and encourage cooperation between yeomen and freedmen under Republican rule, a stark contrast to Johnson's approach. If I had been a member of Congress at the time, to avoid conflict over Reconstruction, I would have proposed a balanced plan that included both protection of freedmen's rights and incentives for reconciliation. It would be essential to involve both Northern and Southern leaders in formulating this plan and maintaining a focus on rebuilding the national economy while avoiding punitive measures that could instigate further division.
Addressing the internal divide in the Republican Party, it would have been crucial to reconcile the aims of the Liberal Republicans, who advocated for a smaller federal government role and emphasized states' control over Reconstruction efforts. This reconciliation would involve ensuring that federal oversight was not perceived as overreach but as necessary support to protect the legal rights of all citizens and maintain social order.
