When Paul Revere went racing through the streets on horseback yelling "the British" are coming, it was these British he was speaking of, coming to take back what they believed was theirs, namely - America. It was, among many issues, taxes and religion that prompted the separation from Britain, and it was Great Britain who was the chief player in the American Revolution.
There were 13 colonies at the time of the American Revolution, thirteen colonies that would shortly after, become the beginning of the United States of America. The names of the heroes of the great war for independence are etched in the history books, and through many hallowed halls in the US. This wasn't a war that involved Great Britain and the rebel colonies alone though. At the time, Great Britain was the world's great power, and there was a lot at stake
It wasn't until 1778 that France jumped into the fray, but as it has for as long as history records, this proud country stood by us and fought beside us. Yes, there was also motive and motivation for the French to join us, after all, they were rather tired of getting their butts kicked by the Brits. They also had some potential land in this place called North America they had designs on claiming.
The role Spain played benefited the Colonies, but not for the Colony's sake. Spain became involved shortly after the French, but only to ally with the French and to fight against the British. Funny, how common enemies make fast friends, and in this case, worthwhile allies.
Following a common theme, the small country of Mysore from India joined forces with the Colonies to fight against British expansion. Great Britain during their reign made more than a few enemies, many of which made good during the America Revolution.
The Dutch Republic
Despite their size, the Dutch Republic owned a formidable fleet of ships. Great Britain's attack on the Dutch Republic to prevent them from joining the revolution sealed the deal for whose side they were on.
Not everyone was willing or able to join forces against the British Empire, including territories like Hanover. Today, that would be what we know as Germany and was then under the rule of King George III. That also meant allegiance to the crown and the hand to bore the rod.
Many Native Americans also joined in the revolution, with many of them fighting for either side. Some took up arms against what they considered the invasion of the Colonists, while many tribes were either persuaded or bought by one side or the other.
