Between the years 1778 and 1783, the nations of France and England disputed a war between each other. Both nations were the greatest powers on Earth during that time, and the conflict was a result of both parties trying to beat the other in relation to the amount of colonies they had, specially in America.
It can be said that the biggest winner of this conflict was neither France or England, but the United States of America. The north-american country benefited from the conflict for many years, simply by serving both sides.
