US American historians always try to frame the Revolutionary War as being about political rights and freedoms, and being important in the development of liberal democracy.
This is patently ridiculous because the major causes of the war were all economic, not political. It was about imperial exploitation of colonial possessions.
It is true that the US was one of the prototypical liberal democracies and that liberalism was considered a radical and dangerous philosophy in the 18th and early 19th centuries. It continues to be considered radical in the US even today, apparently.
Nevertheless, any picture of the US Revolutionary War is incomplete without materialist analysis. The first Industrial Revolution began in Great Britain in 1760ish, after all. But US historians are not dialectic materialists, so the effect of class and material circumstance on the war is largely unstudied.
