The Treaty of Brownstown was between the United States and the Council of Three Fires (Chippewa, Ottawa, Potawatomi), Wyandott, and Shawanoese Indian Nations.
It was concluded November 25, 1808, at Brownstown in Michigan Territory, and provided cession of a strip of Indian land for a road to connect two disconnected areas of land previously ceded by Indians in Michigan and Ohio.
With the Treaty of Greenville in 1795 the Indian Nations ceded southern and eastern Ohio to white settlement.
[2] In 1807, the Treaty of Detroit called for the cession of lands northwest of the Maumee River, mostly in the Territory of Michigan.
[3] The area between the Maumee River and the 1805 boundary remained Indian Lands, and thus, the United States could not legally build a road connecting settlements in Ohio and the Territory of Michigan.
