What were the main effects of the American Revolution?

The
conclusion of the American Revolution in 1783 had many different effects on both North America
and the world.

The most immediate effect of the end of the revolution was the
independence of the colonies. It was not known immediately after if the colonies remain
independent republics or if they would form into a nation, but the independence of the colonies
changed the geopolitical reality of the late 1700s.

Britain lost a
considerable amount of territory at the end of the war. In addition to the colonies themselves,
the entire interior of North America, a region known as the  Ohio River Valley, was lost. This
area would provide the U.S. with the opportunity for expansion after the fighting
ended.

The effect on the British economy was also sobering. With their
largest market gone, British trade revenues plummeted. It took Britain many decades to recover,
especially since they had a new global competitor for markets that had always been
theirs.

The introduction of Americans into the world of European politics
also had major repercussions. During the wars of the next few decades, the colonies were a weak
but strategic presence in many conflicts, even when it didnt want to be. Some nations impressed
American sailors while others hired them out as privateers.    

The biggest
effect of the revolution was how it inspired numerous subsequent revolutions around the globe.
Using the colonies as their model, France had their own revolution in 1789. From that point on
most global revolutions, even some very recent ones in the Middle East, borrowed from the
playbook of America when they began their own struggles for independence.
