Please answer this: Extract the answer to the question from the following context. Question: Which tribe name is mentioned? Context: European colonists created treaties with Indigenous American tribes requesting the return of any runaway slaves. For example, in 1726, the British governor of New York exacted a promise from the Iroquois to return all runaway slaves who had joined them. This same promise was extracted from the Huron Nation in 1764, and from the Delaware Nation in 1765, though there is no record of slaves ever being returned. Numerous advertisements requested the return of African Americans who had married Indigenous Americans or who spoke an Indigenous American language. The primary exposure that Africans and Indigenous Americans had to each other came through the institution of slavery. Indigenous Americans learned that Africans had what Indigenous Americans considered 'Great Medicine' in their bodies because Africans were virtually immune to the Old-World diseases that were decimating most native populations. Because of this, many tribes encouraged marriage between the two groups, to create stronger, healthier children from the unions.

Extract the answer to the question from the following context. Question: What happened in the 57th year of the 18th century?

Fort Loudoun became the westernmost British outpost to that date. The fort was designed by John William Gerard de Brahm and constructed by forces under British Captain Raymond Demere. After its completion, Captain Raymond Demere relinquished command on August 14, 1757 to his brother, Captain Paul Demere.

natural barriers of desert and mountain
