“while American founders ended up being friends in later years; one “minor” civil war”
I’m not sure yet how much I want to wade into this thread, but the US Civil War was most certainly not “minor”. The war killed close to three quarters of a million soldiers, which, considering the population at the time, makes the conflict one of the deadliest in human history. Divisions over slavery and the balance of Northern and Southern power began shortly after American independence and roiled for decades before Lincoln’s election and South Carolina’s secession and shelling of Fort Sumter. The impacts of the war continue to affect many southern states generations later, and it is difficult to understand the United States without knowledge of the war. True, the conflict did not spill over borders into other countries, but the Battle of Gettysburg was on par with Waterloo, and the Civil War was the first “industrialized” conflict, forever changing how wars are fought.
