Question

How did the nation try but fail to deal with growing sectional differences

Answer 1

There are several things that the nation tried in order to deal with growing sectional differences:
- Northerners refused to accept the fugitive slave act
- John brown and his followers protested slavery in Virginia
- after Lincoln won the election some states seceded from the union 
- civil war began when confederate troops fired on fort Sumter
