True enough but the war started before 1861 (1850-1860 give or take) with northern strong-arming, voter gerrymandering, and tariffs. The shooting started in 1861.
Wuh???
You sir win a cigar. The shooting almost started 20-30 years earlier but was advert end through compromise which made the north greedier and pushed harder.
“Bloody Kansas” was going for what, ten years?, before the Civil War started.
