The Revolutionary War was a war fought because United States wanted it's own independence from United Kingdom.
Centralized power: all their power went up efficiently and bureaucratically (although that may seem like an oxymoron) to one small group of people. In one case, the Caesar and the Senate (which still had a role during the Pax Romana); in the second case, the Pope and his Cardinals.
I think it's political reasons because at the time they had many of political reasons. Also, the American Civil War was acctually about politics. People were thinking about political things that could be changed.
That's all I got. Hope this helps.
It imposed fines for hiding runaway slaves.
