I am glad the North won, but Reconstruction was a disaster. Lincoln's death meant the end to a reasonable, unifying Reconstruction and opened the door to a vindictive, unjust Reconstruction.
The Southern Fire-Eaters who spread ridiculous lies about Lincoln during the 1860 election should have been imprisoned for life. Lincoln had no intention of fomenting slave revolts and had no interest in abolishing slavery where it already existed.
Southern apologists usually fail to mention that after the 1860 election, the South still controlled the Senate, and that the Republicans actually lost seats in the House. If Southern hotheads had not rushed into secession after the election, the South could have blocked any unwanted legislation in the Senate. But, when Southern senators resigned from the Senate, the Republicans gained control, and when Southern congressmen resigned from the House, the Republicans increased their majority.
