Definition
The Convention of 1800, also known as the Treaty of Mortefontaine, was a diplomatic agreement signed on 30 September 1800 between the United States and the French Republic that formally ended the undeclared naval conflict known as the Quasi‑War (1798–1800).
Overview
Negotiated after two years of hostilities, the convention was concluded in the French village of Mortefontaine (now part of the commune of Sèvres, Île‑de‑France). It was signed by American envoy John Jay and French Foreign Minister Charles‑Maurice de Talleyrand‑Périgord. The United States Senate ratified the treaty on 21 February 1801, and France ratified it on 3 April 1801.
The agreement terminated the naval engagements and piracy accusations that had arisen after the 1797 XYZ Affair, restored commercial relations, and set the framework for future Franco‑American trade. Although the treaty was less favorable to the United States than some contemporaries had hoped, it succeeded in averting a full‑scale war and allowed both nations to focus on other strategic concerns—France on wars with the Second Coalition and the United States on westward expansion.
Etymology / Origin
The term “Convention of 1800” derives from the diplomatic practice of referring to treaties by the year of signing. The alternative name “Treaty of Mortefontaine” references the location where the agreement was negotiated and signed.
