The End of the Quasi-War
The only fighting in the Quasi-War occurred at sea, and mostly in the Caribbean. But with war at a fever pitch and French interests so close by in Louisiana, there was a very real concern in Congress about a possible French invasion of the United States from the west.

The Quasi-War with France
Between 1798 and 1800, the United States fought an undeclared war with France called the Quasi-War, or Half War, because it was not formally recognized by Congress. It was largely a naval conflict fought in the Caribbean and southern coast of America and developed because of a series of related events that soured the formerly strong relationship between the two nations.

Relations with France Fall Apart
America’s first armed conflict with a foreign nation following the American Revolution was not the War of 1812, but rather a mostly forgotten fight called the Quasi-War. Although little known today, in its time it made a significant impact on the course of American history, affecting trade, the creation of the United States Navy, and a presidential election.
