I agree. In fact, growing up in the 70s/80s, I was taught about the ‘American War of Independence’. This was in the UK.
You said it! They stink on ice!
(Preamble to the Declaration of Independence)
Based on this, the CSA averred that their right to secede was based on the same grounds that the Colonies seceded; i.e., separated from the existing government to form their own government. If the South were victorious, it would’ve been America’s second revolution, which is the way many in the South refer to it. So, call it a “revolution” or “civil war” it is, as the Brits say, a war of independence.
BTW, many in the South refer to it as the War of Northern Aggression.
The classic difference between a ‘rebellion’ and a ‘revolution’ is who got hanged when it was over and done.
I’m going to disagree some. There were some revolutionary ideas that come out of the US revolution, largely related to self-governance. The US Constitution was the first time that the citizens of a country voted for/against the form of government proposed.
The difference, however, is that the American colonies did not have direct representation in the government. The Southern states did.
