The first country to recognize the United States as an independent nation was France. This recognition came after the United States declared its independence from Great Britain in 1776. France, under King Louis XVI, saw an opportunity to weaken British power and support the American colonies in their struggle for freedom. Formal diplomatic relations were established in 1778, when France signed a treaty of alliance with the United States, providing vital military assistance and financing. This alliance played a significant role in the American victory in the Revolutionary War, contributing to the establishment of the U.S. as an independent nation.
