What are the causes of the civil war and how was it connected to slavery

the civil war happened between Northern states and southern states because the northern states wanted abolish slavery and the southern states didn't want to.

Explanation:

*the northern states were called the "union states".

*the southern states were called the "confederates"

Now the reason why the southern states didn't like the idea of abolishing slavery was because the confederates were farmers and the state was in an agricultural type of time and they wanted the slaves to do their job in farming and abolishing these slaves, for them it meant that they were the ones who needed to work.  

the civil war ended with the union states winning and abolishing of slavery started.
