Following defeat by the English during the war, the French ceded their territory in North America east of the Mississippi River to England. The English signed the Treaty of Fort Stanwix (1768) with the Iroquois, under the terms of which they promised to preserve areas west of the Appalachian Mountains as an Indian reserve and to prohibit colonial settlement. It has been described as one of the worst treaties in the History of Anglo-Indian relationships. The treaty has also been described as the last desperate effort of the British to create order west of the Appalachians. The British were unable to enforce their promise, as Anglo colonists continued to move west of the Appalachians, causing conflicts with native tribes. The British abandoned Ft. Stanwix after that war; it deteriorated and was eventually torn down, its parts and materials used by settlers for other structures.
