Explain two ways in which sectionalism caused conflict or tension in the united states during the early 1800s. then explain how sectionalism affects economics and politics in the united states today.

In the 1800s, sectionalism was demonstrated in economic terms and in terms of slavery. The states in the North did not own slaves, and a lot of industry was beginning to take shape there, so the population was becoming more rural. Meanwhile, the South was primarily farmers and had slaves. This situation eventually resulted in the Civil War.
 
The modern US as both more and less sectionalism than before. It is now usually expressed in political and social issues. You can see certain areas of the country, particularly the southeast and midwest, is both more conservative in social matters and generally votes Republican. Then you have the northeast and west coast that are more liberal and vote Democrat.
