Genrish500 [490]

Answer:

1. Slavery

The South relied on slavery for labor to work the fields. Many people in the North believed that slavery was wrong and evil so they wanted slavery to be illegal throughout the United States. This made wealthy landowners in the South fearful that their way of life would come to an end.

2. States' Rights

Since the Constitution was first written there had been arguments about how much power the states should have versus how much power the federal government should have. The southern states felt that the federal government was taking away their rights and powers.

3. Expansion

As the United States continued to expand westward, each new state added to the country shifted the power between the North and the South. Southern states began to fear they would lose so much power that they would lose all their rights.

****While there were many political and cultural differences between the North and the South that contributed to the American Civil War, the main cause of the war was slavery.
