Which of these actions was an economic cause of increased tensions between the North and South? Dred Scott decision
Protective tariffs
Bleeding Kansas
Lincoln’s election

The protective tariff was an economic cause of the increased tension between the North and the South.

Economically, the North had a lot of factories and had become industrialized. The south on the other hand still depended heavily on Agriculture.

High protective tariffs were placed on foreign goods to favor the Northern Industries. This meant that people had to buy more from the North.

In conclusion the protective tariffs helped to boost the economy in the North while hurting t the south.
