Lincoln supported the Union and opposed secession. The Southern states believed that they had the right to secede from the Union and form their independent country. Lincoln, on the other hand, believed that the Union was indivisible and that secession was illegal.
Lincoln was seen as a Northerner who did not understand or sympathize with the South. Many Southerners felt that Lincoln and the Republican Party were hostile to their region and their way of life.
The Emancipation Proclamation. Lincoln issued the Emancipation Proclamation in 1863, which declared that all enslaved people in the Confederate states were free. This proclamation effectively ended slavery in the United States and further infuriated the South, who saw it as an attack on their way of life and a violation of states' rights.
In conclusion, the combination of these factors led the Southern states to hate Abraham Lincoln and contributed to the outbreak of the American Civil War.
