Sectional Tension

The people in the Northern states and Southern states became more and more politically, socially, and economically divided.

Sectional Tension

The cotton gin caused the Southern states to follow its agricultural ways, while the Northern states became more industrialized (they could not grow cotton in the North - too cold)

Northern and Southern states found it increasingly difficult to relate to one another, especially when it came to the topic of slavery

They began to see themselves as separate “sections” of the nation - sections which had very little in common

Sectional Tension

Several compromises were attempted by both sides to try and overcome the problems between them regarding the slavery issue

All compromises eventually failed The result would be the build-up

of sectional tensions which would eventually lead to war
