The American Revolutionary War happened because we didn't like Great Britain bossing us around without our representation. We were taxed heavily for a war that did benefit us, but we just didn't want to pay for it because we didn't decide to start the war with France, Britain did. We also didn't like how much the government ruled over us, so that's another reason. We had little say in much when it came to court rulings, British subjects always were tried in a British court instead of an American court. And to answer that last bit, yes it was revolutionary.
