The northern states such as Pennsylvania, wisconsin, washinton,were against slavery while the southern states were for it.
Slavery in the United States wasn't saved it was defeated.
There were two Missouri Compromises. They were created in 1820 and 1850. Both of them were reached in order to maintain a balance between States that had abolished slavery and those States were slavery still existed. The compromises served and had a noble purpose. They were not made to in effect to justify slavery. The purpose of both of them was to avoid a serious conflict among the States. When seen in that light, the compromises delayed a civil war in the United States.

The southern states' rights and slavery
The 13th amendment to the Constitution abolished slavery in the USA, and it was adopted on December 6, 1865. However, the state of Mississippi didn't "ratify" (to make it official) it until 1995. Kentucky didn't ratify until 1976. See the link below for further explanation. However, these two states not ratifying the 13th amendment until much after 1865 is considered to have only been symbolic. The federal law abolishing slavery still made it illegal for anyone in these states to own a slave.
