What was the most civil civil war?

In My Humble Opinion
1

Exactly what the title says.

2

Czechoslovakia split up in what was known as the Velvet Divorce.

3

The Glorious Revolution, where William of Orange usurped the throne of James II without much of a fight.

4

Actually, they acted in a gentlemanly fashion by taking the fight outside, namely to Ireland.

5

But the Velvet Divorce was notable for it’s lack of war, thus making it ineligible.

6

I figure a lack of war, by definition, is more civil than a war.

Apparently political scientists define a civil war as an intrastate conflict with at least 1000 deaths per year and at least 100 of them on each side. The correlates of war data set for intrastate conflict shows… lets see… the Fifth Chad Civil War (2005-2006) had about 1000 casualties on one side and 100 on the other and so had close to the lowest number of deaths possible while still being called a civil war. So technically speaking, there you are.

Slovenia managed to get out of Yugoslavia while the rest of the country was busy slaughtering each other. There were only 63 KIA in it’s 10 day war of independence Ten-Day War - Wikipedia.
