The answer is:
" Slave revolts were the great societal fear in the South. Nat Turner’s was simply the largest and deadliest in the US. It’s impact was not on the war itself, per se, but on the culture of fear that predominated in the South, which lead to mistrust of Northern intents and purposes, and increased militarism, that lead to war being seen as a viable option and contributed to the early successes of the Confederacy on the battlefield.
This fear is of slave revolt was not new. The reason the Spartans created the agogi and trained as professional soldiers was because they conquered and enslaved the helots who were the majority population of Lakonia. The Spartans trained as soldiers because they lived in constant fear of being murdered in their beds by helot slaves.
Nat Turner’s rebellion also came within the living memory of the Haitian Revolution and massacre of the white French population that followed. These revolts and every subsequent slave revolt, increased the militancy and paranoia of white Southern society. Prior to the Civil War slave states funded their militias better, and drilled more vigorously and sent more sons to military schools than their free state counterparts. In fact, while only the Citadel and VMI remain as fully military schools, every Slave state had a state military college. LSU and the Texas A&M roots lie in these Military Colleges. Of the six “Senior Military Colleges” that still exist outside of the Service academies five are in former slave states.
The key to understanding the impact on the Civil War was that it wasn’t just slave-owners who feared slave revolts. It was non-slave owning white farmers as well. Turner’s revolt went from house to house freeing slaves if they found them and killing whites when they encountered them. Non-slave owners had just as much to fear as slave owners did. This is why the argument that the Civil War was not about slavery, because so many non slave owners fought, doesn’t hold true. Non-slave owning farmers enthusiastically joined the militias and posses to put down slave revolts when they occurred to protect their families.
