15. The Quasi-War (1798-1800)
The Quasi-War was an undeclared naval conflict between the United States and France from 1798 to 1800. (history.com) Tensions arose after France began seizing American merchant ships trading with Britain, leading to the U.S. Congress authorizing military force without a formal declaration of war (history.state.gov).The conflict primarily occurred at sea, with the U.S. Navy capturing over 80 French vessels. The hostilities concluded with the Convention of 1800, which ended the conflict and terminated the 1778 treaties of Alliance and Commerce between the two nations.
