Why is the american revolution so important? ? hurrry need fast

...Its the reason why you have your freedom? The reason we aren't under the control of the British Empire? Why didn't you learn this in second grade? It was the reason America is well... America. It was the first war America fought for the freedom of her people. One could argue the most important war in American history, and possible even the WORLD for that matter, because who knows what the world would be like today if America didn't come to be. 

In terms of American history, it is crucially important because without the Revolution, there would be no United States today. In terms of world history, it was the first instance of a new country being birthed from under the control of another. hope it helped :)
