To what extent did the American Revolution fundamentally change American society?
There is some amount of debate on this topic.
On the one hand, it is clear that the Revolution did not cause a visible transformation in American society. The class that held power in the colonies before the Revolution still largely held power after the Revolution. There was no takeover of power by the common people and no other huge social changes.
However, there are those, like Gordon Wood, who argue that a hugely important change did take place. Wood argues that American society had been held together by vertical ties between superiors and inferiors before the Revolution. He argues that the rhetoric of the Revolution dissolved these ties and replaced them with lateral ties between people who all saw themselves as equals. Wood argues that this constitutes a fundamental, if somewhat invisible, change in American society.
