russia and spain
spain and great britain

FRANCE and SPAIN are the countries that became colonial allies during the American Revolution.

The Netherlands also gave support to the American colonies during the revolution but France gave the most support to them. 

These European nations helped American colonies fight against Britain because of the following:
1) Britain is their common enemy. This is where "the enemy of my enemy is my friend" applies.
2) Spain and France wanted to exact revenge against Britain for their losses in the Seven Years' War.
3) Aside from recouping territorial losses after the Seven Years' War if American colonies defeat Britain, European allies will have new trading partners in the colonies.
4) European people also belief in fighting for independence. They support American colonies in fighting for its freedom from Britain's rule. 

It has the potential to lead to limits on rights by giving flexibility in making laws.
