Fort Loudoun was a British fort located in what is now Monroe County, Tennessee. Constructed from 1756 until 1757 to help garner Cherokee support for the British at the outset of the French and Indian War, the fort was one of the first significant British outposts west of the Appalachian Mountains. The fort was designed by John William Gerard de Brahm, while its construction was supervised by Captain Raymond Demeré; the fort's garrison was commanded by Demeré's brother, Paul Demeré. It was named for the Earl of Loudoun, the commander of British forces in North America at the time.
