How did the American Revolution change the world?

It gave other countries under foreign rule the realization that

·         They didn't have to put up with a monarchy that was not responsive to their wishes.

·         The idea that the common man should have a "voice" or participation in their government. Introduced governmental concept from a monarchy to an oligarchy/democracy.

·         They did not have to live under British rule.

 

The country that was born from it, the United States of America, has grown to be one of the most powerful nations in the entire history of the world.
