The Convention of 1800, also known as the Treaty of Mortefontaine, was signed on September 30, 1800, by the United States and France. The difference in name was due to Congressional sensitivity at entering into treaties, due to disputes over the 1778 treaties of Alliance and Commerce between France and the U.S.
