Which event was MOST important for U. S. History?
•American Revolution
•Civil War

The american revolution would be the answer because
the american revolution was the first of the atlantic revolutions that influenced the rest of the revolutions in modern history.
by coming out victorious in this revolt, the americans showed the world that the united states had what it takes to take down a global super power (Britain) and be able to compete with the other super powers on the world stage
hope this helps!
