Answer: yes (kinda)
Step-by-step explanation:
The Civil War in the United States began in 1861, after decades of simmering tensions between northern and southern states over slavery, states' rights and westward expansion. The War Between the States, as the Civil War was also known, ended in Confederate surrender in 1865.
Basically, the confederates surrendered and slavery was sorta gone. Not completely gone. But A LOT of it was gone. So technically the civil war did end regional conflicts in America
