Once the Civil War was over, Abraham Lincoln had planned to be lenient with the South so the country could heal. But Lincoln was assassinated shortly after Lee surrendered. Without Lincoln, Congress was harsh. They placed Southern governnments under military rule.
Around 200,000 troops were placed in the South to enforce military rule. Thousands of government officials were removed from office in the South and replaced with military commanders. Former slaves were placed in positions in government under military commanders. These slaves were not trained for their jobs in most cases. They knew nothing of government or of money.
Instead of healing the South, military control caused a great deal of hatred and discontent. Military rule in the South lasted until the Republican party agreed to return Southern states to home rule in exchange for their support of the Republican candidate for president, Rutherford B. Hayes in 1877. That was the end of reconstruction.
