The US is a weird example of an armed revolution because it was a colonial revolt largely by people who already had power and were part of the colonial governments. The layer of government that was being scraped off was relatively thin, locally. For example, both Washington and Jefferson were in the Virginia House of Burgesses, and they're just the first two I googled to find out the details of their pre-Revolutionary political careers.

If the Confederacy had succeeded in seceding, it would have been a very similar revolution - the state governments on down would remain intact, with just a little bit at the top being rearranged. I'm not sure I could name a third, similar armed revolution off the top of my head; most of the ones I'm familiar with involve charismatic outsiders burning down the existing institutions and starting over fresh.
