The correct answers are A) economic differences, C) states right's, D) social differences, and E) the issue of slavery.
<em>The causes of sectionalism were economic differences, states right's, social differences, and the issue of slavery.</em>
The Northern and Southern states had different political and economic conditions. Furthermore, the issue of slavery really represented a big difference between people that supported slavery in the South and abolitionists in the North. Sectionalism implied that the United States was severely divided and this was a major cause of the Civil War. Americans were loyal to their side, not to the whole nation.
