What was the main reason slavery died in the north, but lived in the south

Northern states didn't need it, but southern states did.

Explanation:

Southern states needed slaves to harvest and grow crops because it was a lot of work and easier for someone to do it for you. Northern states didn't grow crops because it was colder up north.
