Senator from Ohio, and ninth President, served March-April 1841), Caleb Swan (1758-1809), William Clark (1770-1838), and Meriwether Lewis (1774-1809) - the last two to become more famous a decade later (and for the subsequent two and quarter centuries), leading the Lewis and Clark exploring expedition (Corps of Discovery) of 1804-1806, into the new western Louisiana Purchase of 1803, up the Missouri River across the Great Plains, through the passes of the Rocky Mountains, to the Pacific Northwest region and the West Coast of North America on the Pacific Ocean and returning.

Following their defeat at the Battle of Fallen Timbers in August 1794, and subsequent scorched earth tactics, General Wayne had courted the favor of several key leaders within the Western Confederacy.

[4] Blue Jacket, the Shawnee war chief who had led the Native American force at Fallen Timbers, encouraged others to accept Wayne's offered terms for peace.

Tarhe declared that the victory at Fallen Timbers was evidence that the Great Spirit favored the newly-arrived white men from across the mountains to the east and ocean, called Americans.

[4] General Wayne revealed to the chiefs that the U.S. Senate in Washington had recently ratified the Jay Treaty, between the Americans and the British, and what that would mean on the western frontier, ensuring that Great Britain in northern Canada (Quebec and Ontario]), would no longer be providing additional aid, supplies, firearms and ammunition to the Native Americans.

[5] Tarhe confirmed that previous treaties had been signed by chiefs who were at Greenville and warned his fellow Indigenous tribal leaders that Wayne had the military power to take all of their lands if they did not negotiate.

For several years, it distinguished Native American territory from lands open to European-American settlers, who, however, continued to encroach.

In exchange for goods to the value of $20,000 (such as blankets, utensils, and domestic animals), the Native American tribes ceded to the United States large parts of modern-day Ohio.

That institutionalized continuing government influence in tribal affairs and gave outsiders considerable control over Native American life.

Rufus Putnam, who had been appointed by George Washington as surveyor general of the United States, surveyed and marked the Treaty Line.

[17] The treaty also permitted established US Army posts and allocated strategic reserved tracts within the Indian Country to the north and the west of the ceded lands, the most important of which was the future site of Fort Dearborn (now Downtown Chicago) on Lake Michigan.

[12] The United States renounced all claims to indigenous peoples' lands not within the treaty line in Ohio or parcels exempted.

The indigenous groups were obliged to recognize the United States as the sole sovereign power in the entire territory, but the local peoples would otherwise have free use of their own lands as long as they were kindly disposed to American settlers.

[25] Unrest among the tribes culminated in the Battle of Tippecanoe in 1811, a major defeat for indigenous nations that may have contributed to their siding with the British in the War of 1812.
