I would say that three important influences on the growth of democracy in America were the American Revolution that forged a new independent republic with its own constitution, the Civil War and also the Civil Rights Movement that resulted in much greater freedom for black Americans and also the protests against the war in Vietnam which eventually were successful in helping end that unjust war and showing that when aroused citizens take action against such a war they can succeed in helping to end it when it becomes so unpopular and so anti- human as it did.
