My foreign history is hazy. In the American civil war who was the goodies and who were the baddies?

You had the Union, the Northern States and the Confederates, the Southern States. The Union wanted to abolish slavery and the Confederates wanted to keep it. The North had the majority of the industry and the South had the farms and Plantations. The South needed the labor. That's why they favored Slavery. Since the Union won history flavors the winner so the Union is the good guys. Both my mom's and dad's side of the family fought for the Union.
