Final answer:
The Battle of Saratoga resulted in France forming a military alliance with the American colonists, providing them with crucial support that helped lead to the eventual defeat of Great Britain.
Step-by-step explanation:
One outcome of the Battle of Saratoga was that the American victory convinced France to form a military alliance with the colonists. This turning point in the American Revolutionary War meant that France not only recognized American independence but also decided to supply the United States with gunpowder, money, and military forces, including the well-known Marquis de Lafayette as one of its leaders. The entry of France into the war was instrumental in the eventual defeat of Great Britain, as it stretched the British forces thin by requiring them to defend against the French in the West Indies and Europe.
