The other main cause of the Civil War, Sates rights, was an other disputed topic between the North and South. The South thought that they didn't have enough rights compared to the North. The north had a lot of voting power. For example Abe Lincoln won every North state and lost every South state but still won because the north had more political power. One thing that sent the South over the edge was when Kansas and California became free even though they were below the 36-30 line. Most of the same people were involved in the states right fight as well as the slavery fight.
