The relationship between France and the United States was historically important in the latter's independence from the United Kingdom, and continues to be strong into the present day.

Post-Columbian era

New France () was the area colonized by France beginning with exploration in 1534 and ending with the cession of New France to Great Britain and Spain in 1763 under the Treaty of Paris.W. J. Eccles, The Canadian Frontier, 1534–1760 (1969) onlineFor historiography see Allan Greer, "National, Transnational, and hypernational historiographies: New France meets early American history." Canadian Historical Review 91#4 (2010) pp 695–724 doi=10.3138/chr.91.4.695

The vast territory of New France consisted of five colonies at its peak in 1712, each with its own administration: Canada, the most developed colony, was divided into the districts of Québec, Trois-Rivières, and Montréal; Hudson's Bay; Acadie in the northeast; Plaisance on the island of Newfoundland; and Louisiane. It extended from Newfoundland to the Canadian Prairies and from Hudson Bay to the Gulf of Mexico, including all the Great Lakes of North America. The colony of Louisiana (New France) became part of the United States between 1776 and 1803, but outside of what is now the state of Louisiana it had a very small French population.

Population grew steadily because of high birth rates and good food supplies. In 1754 New France's population consisted of 10,000 Acadians, 55,000 Canadiens, while the territories of upper and lower Louisiana had about 4,000 permanent French settlers, summing to 69,000 people.

The British expelled the Acadians in the Great Upheaval from 1755 to 1764. Their descendants are dispersed in modern Canada and in the U.S., in Maine and Louisiana.

French and Indian wars Beginning in earnest after 1688, the simmering dynastic, religious and factional rivalries between the Protestant Britain and the larger power Catholic France triggered four wars in Europe that spilled over into North America. They were "French and Indian Wars" fought largely on American soil (King William's War, 1689–1697; Queen Anne's War, 1702–1713; King George's War, 1744–1748; and, finally the Seven Years' War, 1756–1763). The French made allies of most of the Indian tribes and enabled them to attack villages in New England. Great Britain won and finally removed the French from continental North America in 1763.Max Savelle, The Origins of American Diplomacy: The International History of Angloamerica, 1492–1763 (1967) onlineBetsey Maestro, Struggle for a Continent: The French and Indian Wars: 1689-1763 (Harper Collins, 2000).

In 1763, France ceded almost all of New France to Britain and Spain, at the Treaty of Paris. Britain took over Canada, Acadia, and the parts of French Louisiana which lay east of the Mississippi River, except for the Île d'Orléans. Spain was granted all the French claims to the west of the Mississippi River. In 1800, Spain returned its portion of Louisiana to France under the secret Treaty of San Ildefonso in 1800 imposed by Napoleon Bonaparte. He sold it all to the United States in the Louisiana Purchase of 1803, permanently ending French colonial efforts on the American mainland. New France became absorbed within the United States and Canada. In the United States, the legacy of New France includes numerous place names as well as pockets of French-speaking communities.William R. Nester, The first global war: Britain, France, and the fate of North America, 1756-1775 (Greenwood, 2000).

Post-American Revolution

Within a decade of the French being expelled in 1763, the British colonies revolted openly. In retaliation, France, led by Luis de Unzaga y Amézaga, secretly provided troops and war materials to the independence movement.Cazorla, Frank, G. Baena, Rose, Polo, David, Reder Gadow, Marion (2019). The governor Louis de Unzaga (1717-1793) Pioneer in the birth of the United States of America and in the Liberalism. Foundation. Malaga

After the Second Continental Congress declared independence in July 1776, its representatives in Paris recruited officers for the Continental Army, most notably the Marquis de Lafayette, who served with distinction as a major general. Despite lingering distrust of France, the representatives also sought a formal alliance. After preparing their fleet and witnessing the U.S. victory at the Battle of Saratoga in October 1777, the French concluded treaties of commerce and alliance on February 6, 1778, committing themselves to fight Britain until the independence of the United States was secured.C. H. Van Tyne, "Influences which Determined the French Government to Make the Treaty with America, 1778," American Historical Review (1916) 21#3 pp. 528–541 in JSTORJonathan R. Dull, A Diplomatic History of American Revolution (1985)

The military alliance got off to a rocky start. In 1778, French Admiral d'Estaing sailed to North America with a fleet and began a joint effort with American General John Sullivan to capture a British outpost in Newport, Rhode Island. However, d'Estaing abandoned the operation to confront a British fleet and, despite pleas from Sullivan and Lafayette, sailed away to Boston for repairs. With no naval support, the plan fell apart, and American forces under Sullivan had to conduct a fighting retreat on their own. American outrage was widespread, and several sailors from the Royal French Navy were killed in anti-French riots. D'Estaing's actions during a disastrous siege in Savannah, Georgia further damaged Franco-American relations.Jonathan R. Dull, The French Navy and American Independence: A Study of Arms and Diplomacy, 1774–1787 (1975)

The alliance improved in 1780 with the arrival of the comte de Rochambeau, who maintained a good working relationship with General Washington. French naval actions at the Battle of the Chesapeake enabled the decisive Franco–American victory at the siege of Yorktown in October 1781, effectively bringing an end to major combat in North America.

The nascent United States relied on Catholic France for military, financial, and diplomatic aid, leading to a significant decrease in anti-Catholic rhetoric.Francis Cogliano, No King, No Popery: Anti-Catholicism in Revolutionary New England (1995) pp 154-55 The historian Francis Cogiano argues that the king replaced the pope as the common enemy. Although anti-Catholic sentiment remained strong among Loyalists who chose to stay in the new nation, legal toleration for Catholics had been established across the United States by the 1780s, including in New England, a region historically known for its hostility towards Catholicism. Cogliano wrote: "Amidst war and crisis, New Englanders relinquished not only their allegiance to Britain but also one of their deeply held prejudices."Francis Cogliano, No King, No Popery: Anti-Catholicism in Revolutionary New England (1995) pp 154-55, quote p 155.

Peace treaty

During the peace negotiations between the Americans and the British in Paris in 1782, the French played a significant role. The French Foreign Minister, the comte de Vergennes, had strategically maneuvered to ensure that the American Congress ordered its delegation to follow French advice. However, the American commissioners, Benjamin Franklin, John Adams, and particularly John Jay, correctly understood that France did not want a strong United States. They realized that they would receive better terms directly from Britain. The critical turning point came in September 1782 when Vergennes proposed a solution that strongly opposed the United States' interests. France was exhausted by the war, and everyone desired peace, except Spain, which insisted on continuing the war until capturing Gibraltar from the British. Vergennes then proposed a deal that Spain would accept instead of Gibraltar. According to this deal, the United States would gain independence but be confined to the area east of the Appalachian Mountains, while Britain would take control of the area north of the Ohio River. In the southern area, an independent Indian state under Spanish control would be established as a barrier state to prevent the Americans from accessing the Mississippi River or New Orleans, which were under Spanish control. In response, Jay promptly informed the British that he was willing to negotiate directly with them, thereby sidelining France and Spain. The British Prime Minister, Lord Shelburne, agreed, seeing an opportunity to separate the United States from France and establish a valuable economic partnership with the new country.Charles R. Ritcheson, "The Earl of Shelbourne and Peace with America, 1782–1783: Vision and Reality." International History Review 5#3 (1983): 322-345. The terms negotiated for the Western territories were as follows: the United States would acquire all the land east of the Mississippi River, north of Florida, and south of Canada, with the northern boundary remaining almost the same as it is today.In 1842 some shifts were made in Maine and Minnesota. Additionally, the United States would be granted fishing rights off Canadian coasts and agreed to allow British merchants and Loyalists to attempt to reclaim their property. This treaty was highly favorable for the United States, deliberately benefiting the British perspective. Prime Minister Shelburne foresaw highly profitable two-way trade between Britain and the rapidly growing United States, which indeed materialized. Trade with France remained on a much smaller scale.Richard B. Morris, "The Great Peace of 1783," Massachusetts Historical Society Proceedings (1983) Vol. 95, pp 29–51.Ronald Hoffman, and Peter J. Albert, eds., Peace and the Peacemakers: The Treaty of 1783 (1986)

The French Revolution

Six years later, the French Revolution overthrew the Bourbon regime. In the beginning, the United States was supportive of the changes in France, where the absolute hereditary monarchy was replaced by a constitutional republic. However, as the situation in France deteriorated, with the revolutionary government becoming more authoritarian and brutal, the United States' sympathy waned. Events such as the reign of terror diminished the warmth that the United States had for France. Unlike Thomas Jefferson, who left France in 1789, Gouverneur Morris (1752–1816) was highly critical of the French Revolution. Anne Cary Morris, describing her grandfather's conservative beliefs, stated, "He believed in tailoring the government to suit the condition, character, manners, and habits of the people. In France, this led him to favor a monarchical view, firmly believing that a republican form of government would not suit the French character."Anne Cary Morris, ed.,"The Diary and Letters of Gouverneur Morris; Minister of the United States to France; Member of the Constitutional Convention, etc.," (1888), Vol. I, p. 15.
