 The Treaty ceded the eastern ⅔ of current-day Ohio to white settlers and once again opened up the territory for white settlement.In October, 1798, David Zeisberger, the same Moravian missionary who had founded many of the original missions in the 1770s, returned to the Tuscarawas Valley to found a new mission, Goshen, from where he continued his work to Christianize the local natives.Over the next several years, farmer settlers from Pennsylvania came trickling into the area, and by 1808, the first permanent settlement, New Philadelphia, was founded near the Goshen mission.
