The split between northern and southern Churches during the US Civil war had as much to do with the idea of a Bible belt as did the Scopes trial.
The more liberal Northern anti-slavery Presbyterian Church USA split from the very conservative Southern Presbyterian Church of America. The same is true of the Baptists/Southern Baptists and other Churches.
It would be a mistake to call the Northern Presbyterian Church in the 1850s “liberal.” They were not “more liberal” only “more activist.” The divide actually stems from a religious divide in the Presbyterian Church known as the Old School-New School Controversy. The Old School thought that the Church should stay out of political questions not specifically addressed in God’s Word, whereas the more evangelical New School was very much associated with abolitionism.
The General Assembly of the Presbyterian Church USA was actually always officially moderately abolitionist. In 1795, the General Assembly ruled that slaveholding was not grounds for excommunication but also expressed support for the eventual abolition of slavery. It also called slavery “a gross violation of the most precious and sacred rights of human nature; as utterly inconsistent with the law of God.”
Once the Church split between Old School and New School, Southern Presbyterians overwhelming sided with the Old School.
The Southern Churches embraced a more literalist approach to scripture as the OT laws concerning slavery and the discussion of Ones’imus in Paul’s letter to Philemon supported their desire to continue slavery. This is where fundamentalism took root and is now what we know as the Bible belt.

I don’t think so. During the Civil War era, both Northern and Southern churches were broadly evangelical. This evangelicalism was expressed in different ways in North and South. Northerners took the Bible just as literally as Southerners–they just read it as being opposed to slavery rather than justifying it. For example, Paul calls slavetrading a sin in 1 Timothy 1:10.
Fundamentalism was a reaction to the rise of liberal theology in the late 19th century and early 20th century. Dispensationalism, for example, was seen as an innovation by Northern “liberal” Presbyterians as much as by Southern “conservative” Presbyterians.
If you look at the history of Fundamentalism, what you will find is that much of the leadership and original institutions were actually started in the North by Northern Baptists and Presbyterians. Because of the Southern churches on the whole were somewhat more conservative, it actually meant that there was more urgency to fight back against modernism in the North.
