French colonization of the Americas In 1802 Spain returned Louisiana to France, but Napoleon sold it to the United States in 1803. The French left many toponyms (Illinois, Vermont, Bayous...) and ethnonyms (Sioux, Coeur d'Alene, Nez PercÃ©...) in North America.
France in the American Revolutionary War French involvement in the American Revolutionary War began in 1775, when France, a rival of the British Empire, secretly shipped supplies to the Continental Army. A Treaty of Alliance in 1778 soon followed, which led to shipments of money and matériel to the United States. Subsequently, the Spanish Empire and the Dutch Republic also began to send assistance, leaving the British Empire with no allies.
