The Greenville Treaty Line crossed Knox County as surveyed by Israel Ludlow between 1797 and 1799, running from near Fort Laurens in the eastern part of the state to a point near Fort Recovery, then southwesterly to a point on the Ohio River opposite the mouth of the Kentucky River. The Greenville Treaty was signed on August 3, 1795, and under its terms the Indian tribes gave up their claims to the lands south of and east of this line.
