I only know number 11, i'm sorry. The thirteenth amendment abolish slavery which mean freed slave. The slave is free. It cause the civil war because well slave is the reason why southern grew business. Slave were free and the owners of slave were mad because they can't make more money or grew more Buisness. The difference between northern and southern is the view of slavery is different. Norther aganist while souther is for. Hope it help
