The Greenville Treaty set into motion a process which led DuSable to sell his Chicago holdings. Until then, Indian treaties with Great Britain and the United States had set the Ohio River as the boundary between areas of white and Indian settlement. Following Anthony Wayne's 1794 victory at the Battle of Fallen timbers, Indians ceded over two-thirds of southern and eastern Ohio. In addition, they ceded "one piece of land six miles square at the mouth of the Chikago river, emptying into the south-west end of Lake Michigan, where a fort formerly stood." Within a decade, Fort Dearborn had been established.
