Despite his mastery of diplomacy and Lafayette’s unceasing support at the Court of Versailles, Jefferson’s five years as Minister Plenipotentiary produced only two treaties, one with Prussia in 1785 and one with Morocco in 1786, and a single consular agreement with France in 1789.[6] America’s weak central government under the Articles of Confederation and its then novel idea of free trade as opposed to Europe’s powerful monarchies and their preference for mercantilist trade created an impasse Jefferson was unable to resolve. In France, the corrupt Ferme Générale monopolized trade with individual American merchants and had no interest in a broad trade treaty that would diminish their control over American exports.[7] Complicating matters, the American government struggled to pay off French loans to fund the American Revolution, stopping interest payments in 1785 and defaulting on further installments in 1787, such that the Court of Versailles saw little to be gained from lowering trade barriers between the two countries.[8] Jefferson and Adams both made attempts to deal with the Barbary pirates of North Africa. Lacking an ocean going navy and no longer protected by Britain, American ships and citizens were seized at will by the Barbary pirates who demanded ransoms and steep tribute to free them. Successfully negotiating a treaty with Morocco but meeting with no success with Tripoli, Tunis, and Algiers, Jefferson concluded that only war would stop their incursions. As President, he initiated the Barbary War of 1801-1805 leading to the defeat of the Barbary pirates by the U.S. Navy and Marine Corps.[9]
Undeterred by the lack of progress in formal treaty making, Jefferson sought other means to advance political and economic support for the new American nation. In his dealings with the French Foreign Minister, the Comte de Vergennes and his successor, the Comte de Montmorin, Jefferson forcefully promoted America’s commercial interests, advocating particularly for tobacco and whale oil, the primary export products of that time. In 1786, Jefferson convinced Vergennes to establish an American Committee to improve trade and diminish the influence of the Ferme Générale. Enlisting Lafayette and Pierre Samuel Du Pont de Nemours to serve as members, Jefferson’s efforts opened the tobacco market to more American producers and ended the ban on imports of American whale oil.[10]
Jefferson took the opportunity of his diplomatic posting in France to immerse himself in the sights, culture, and people of Paris and Western Europe, remarking, “Were I to proceed to tell you how much I enjoy their architecture, sculpture, painting, music, I should want words.”[11] These experiences made a profound impact, transforming his thought and taste in virtually every subject that interested him, including:
- Architecture and Design. Paris was the center of neoclassical architecture during Jefferson’s time in France. He fully embraced the blending of old and new design and engineering behind the neoclassical movement and took time during his travels in Europe to view both neoclassical and classical structures and ruins in France, Italy, and England. His reimagining of Monticello reflects the incorporation of neoclassic elements of the domed Halle aux blés and Hôtel de Salm, and the asymmetrical interior and parallel rooms of the Hôtel Langeac. In his designs for the Virginia State Capitol, the residential Poplar Forest, the University of Virginia, and (in consultation with Benjamin Latrobe and James Hoban) the U.S. Capitol and the White House, Jefferson brought the neoclassical movement home to America.[12] Jefferson became enamored with French design, acquiring furniture, dinnerware, table settings, floor coverings, and household objects that enabled him to duplicate at Monticello the elements typical of a Parisian salon.
- Botany. Jefferson explored both the practical and the playful in his botanical pursuits in Europe. Befriending André Thouin, French botanist and Director of the Jardin du Roi/Jardin des Plantes in Paris, Jefferson found a fellow enthusiast in the science of botany. Until his death in 1824, Thouin annually sent Jefferson a box of seeds sourced from around the globe. Catherine de Noailles, Comtesse de Tessé, aunt of Lafayette and keeper of a Parisian salon, provided Jefferson entrée to visit the finest estate gardens and ornamental farms in Paris. In his travels, Jefferson devoted time to studying the crops and agricultural practices of Western Europe with a view to bringing best practices home to America. His tour of the English countryside with John Adams in 1786 resulted in his enthusiastic embrace of English “pleasure gardening” whose concepts he applied to transform Monticello’s landscape into one of integrated and carefully planned informality.[13]
- Science and Technology. In Paris and London, Jefferson seized the opportunity to engage in scientific inquiry and observe advances in technology. He befriended the Marquis de Condorcet, Permanent Secretary of the French Academy of Sciences, who introduced him to the leading scientific figures of France. Engaged in scientific debate with the Comte de Buffon, Jefferson successfully disproved the French naturalist’s theory that North American climate caused degeneration of humans and wildlife by importing examples of American wildlife larger than their European counterparts.[14] During his travels throughout France, Germany, Italy, the Netherlands, and England, Jefferson devoted time to observing the latest developments in engineering and agricultural technology.[15] To his friend John Page, he commented that the “mechanical arts in London are carried to a wonderful perfection.”[16] From London firms, he purchased a vast array of astronomical, meteorological, surveying, engineering, and measuring devices.[17]
- Fine Art. In the company of American artist John Trumbull, Jefferson toured the art academies and art salons of Paris, honing his appreciation of fine art and sparking a desire that American artists might rival those of Europe.[18]. Writing James Madison, he declared, “You see I am an enthusiast on the subject of the arts. But it is an enthusiasm of which I am not ashamed, as it’s object is to improve the taste of my countrymen, to increase their reputation, to reconcile to them the respect of the world & procure them it’s praise.”[19] He engaged sculptor Jean-Antoine Houdon, commissioning works on behalf of the United States, for the state of Virginia, and for his personal use, including busts of himself, George Washington, and the Marquis de Lafayette. During his five years in Europe, Jefferson amassed a sizeable art collection intended for future display at Monticello.[20]
- Food and Wine. Jefferson’s taste in food and wine evolved during his time in Paris, where he came to appreciate French table customs. James Hemings’s training in the art of French cooking and his familiarity with Virginia cooking provided Jefferson the opportunity to combine the best elements of both foodways to create a unique style. Rejecting the fortified wine of England, Jefferson developed a preference for the lighter wines of France, Germany, and Italy. Visiting vineyards throughout Western Europe, Jefferson made extensive field notes regarding viniculture in the hope that America might join Europe in producing fine wine. He adopted the informal “pell mell” seating arrangement typical of the French salon, abandoning the strict order of precedence typical of English table customs.[21]
Jefferson’s encounters with the women he met in Paris are well documented. His correspondence reveals that he met an intellectual equal in Abigail Adams and a horticulture enthusiast in Madame de Tessé, and that he developed a brief infatuation with Maria Cosway.[22] Paris also marked the beginning of Jefferson’s connection with enslaved Sally Hemings, with whom he would father at least four children. A single father, his eldest daughter Martha accompanied him to Paris where she was educated at the Abbaye Royale de Panthemont. Following the death of his youngest daughter Lucy in Virginia, Jefferson arranged for his daughter Mary to travel from Virginia to France in the company of Sally Hemings.
Throughout his tenure as an American diplomat in Europe, Jefferson maintained a keen interest in political events in the United States. In correspondence with James Madison, he closely followed the creation of the U.S. Constitution, offering his advice and opinions on crafting the document. Although generally supportive of Madison’s efforts, Jefferson expressed grave concern that, without a Bill of Rights, the Constitution was fatally flawed and that enabling the President and members of Congress to stand for reelection would risk the creation of officeholders for life. Over time Madison came around to Jefferson’s point of view and drafted the Bill of Rights, amending the Constitution to formally include guarantees of personal freedoms and rights.[23]
