What economic and social factors in the united states led to differing ideas about slavery in the north and the south? explain and support your answer with details.

In the southern United States, slavery was used to help farmers with their fields. The farmers depended on the slaves for their own livelihood. In the northern United States, there was no need for slaves since there was not many farms and no cotton that was grown. The northern people were business owners and the citizens were skilled workers. 

Militarism is the answer.
