Abolishment of Slavery:
Slavery had been around since the 1700's, but the 1787 act separated slavery between the northern and southern states. Ever since the beginning of slavery there had abolitionists who are people going against slavery, trying to end it. When Lincoln became president some southern states seceded afraid he would take away there slavery. He did indeed try and do that so the U.S. went to war with itself and obviously pres. Lincoln won. He then passed the 13th amendment abolishing slavery for good. If this had never happened we could still have slavery present today.
