Final answer:
France came to the aid of the American colonists during the American Revolution, and the success of their revolution later inspired the French Revolution. The Declaration of Independence and the unity of the American colonists served as an example for France and other nations seeking to throw off oppressive governments.
Step-by-step explanation:
The country that came to the aid of the American colonists during their revolution against Great Britain was France. France was inspired by the colonists' success to start their own revolution in hopes of emulating the freedoms won by the Americans. The American Revolution, brought about by the colonies' frustration with British rule, set a precedent for France and other nations seeking Life, Liberty, and the pursuit of Happiness through their own rebellions against oppressive governments. The Declaration of Independence is a notable example of the colonists' determination to establish a new nation founded on these principles.
The Revolution succeeded because the colonists united despite their diverse economic and social backgrounds, rallying against Great Britain. Their efforts culminated in the signing of the Declaration of Independence, a defining moment that not only marked the birth of the United States but also inspired the French Revolution and many subsequent independence movements around the world.
