Which statements were included in the Crittenden Compromise of 1860?

The Crittenden Compromise of 1860 proposed several key amendments to the U.S. Constitution aimed at resolving the sectional tensions between the North and South. It sought to extend the Missouri Compromise line westward, allowing slavery in territories south of the line while prohibiting it in the north. Additionally, it included provisions to protect slavery in existing slave states and suggested that any future states could decide on the legality of slavery through popular sovereignty. However, the compromise ultimately failed to gain the necessary support in Congress.
