The American Revolution would serve as an important stepping stone to creating one of the most powerful sovereign states in the history of man. However just how Revolutionary was the war for independence. The revolution does not seem that compared to other later movements such as the two revolutions in 1917 in Russia, nor would thinkers like Lenin or Kanatchikov use the American Revolution as inspiration. I know that french revolutionists used the incident between the colonists and English as inspiration, but does it go beyond that in terms of influencing later movements?
The problem is that the American Revolution isn't as important as say the French Revolution. As I have written here, the French Revolution has much more impact due to it's ability to project Revolution physically and more important Napoleon was able to spread important aspects of the Revolution (such as legal equality) as far as Poland.
I'm sorry but the American Revolution didn't do much.
I think it inspired later revolutionaries in the rest of the Americas more than in Europe, partly because as you note Europe had its own more ideologically challenging movement a decade or so later. We too easily lose sight of the American independence movement's fundamentally conservative aspects - quite apart from the matter of slavery, this was as much about imagined traditional English liberties as radical notions of democracy - no wonder Bolingbroke was an inspiration for both sides. It was revolutionary in its potential and its implications for the international system, less so in its ideology and the domestic order that resulted.
Why do you think the American Revolution was more "revolutionary" than the Russian Revolution?
