When Cherokee agreed to provide 600 warriors to support the British cause during the French and Indian War, they demanded protection for their families. In 1756, to help its ally, the powerful Cherokee Nation, Great Britain built Fort Loudoun in the Cherokee territory (now Tennessee). It was one of the first significant British outposts west of the Appalachian Mountains. Its main purpose was to protect the Cherokee families while the men fought for British.
Declining relations between the Cherokee and the British resulted in tensions and killings on both sides. Indians attacked Fort Loudoun. In 1760, besieged for seral months British negotiated a surrender. When they left, the fort became abandoned.
