How did the American Revolution affect the world?
The American Revolution affected the world in several ways.
First, it surprised the world that such a small amount of people
would revolt against the grandest army in the world. Then, it was a
financial "burden" of sorts to other countries who sided with the
colonies (like the French). It was also a major influence on other
places where revolts occurred (for example, the French Revolution,
the Haitian Slave Rebellion, etc.).
