Answer:
A key factor in the American victory in the American Revolution was the military assistance provided to the Patriots by France.
Step-by-step explanation:
The American Revolution faced the original Thirteen British Colonies in North America against the Kingdom of Great Britain. It happened between 1775 and 1783, ending with the British defeat in the battle of Yorktown and the signing of the Treaty of Paris.
During the war, France helped American revolutionaries with ground troops commanded by Rochambeau and the Marquis de La Fayette and by fleets under the command of sailors such as Guichen, de Grasse and d'Estaing.
The British colonies that became independent from Great Britain built the first liberal and democratic political system, lighting a new nation, the United States of America, incorporating the new revolutionary ideas that advocated equality and freedom.
