Final answer:
Reconstruction was the process of reintegrating the Southern states into the Union, requiring political and economic transformation rooted in repealing secession, ratifying the Thirteenth Amendment, and considering land redistribution. The process was marked by disputes over the leniency towards former Confederates and visions for a diversified Southern economy.
Step-by-step explanation:
The question regarding how the rebellious Southern states should be reintegrated, both politically and economically, into the Union refers to the period following the Civil War known as Reconstruction. The aim was to bring the former Confederate states back into the Union as equal members. However, the process of Reconstruction was uneven and contributed to lasting poverty in the South, which remained primarily an agrarian society.
To address the political reintegration, Southern states were required to hold state conventions to repeal the ordinances of secession and ratify the Thirteenth Amendment. Economically, there were discussions of land redistribution as a means to compensate former slaves and a punishment for Confederate rebels. In the long term, the vision for a New South included a diversified economy with a blend of agriculture, industry, and reform.
Unfortunately, contentious views between factions such as the Radical Republicans and President Andrew Johnson led to conflicts over the Southern states' readmission to Congress. The Radical Republicans objected to the lenient treatment that allowed former Confederate leaders to return to power. This disagreement prolonged the instability and complexity of the Reconstruction process.
