Tecumseh was outraged by the Treaty of Fort Wayne, and thereafter he emerged as a prominent political leader. Tecumseh revived an idea advocated in previous years by the Shawnee leader Blue Jacket and the Mohawk leader Joseph Brant, which stated that American Indian land was owned in common by all tribes, and thus no land could be sold without agreement by all. Tecumseh knew that such "broad consensus was impossible", but that is why he supported the position. Not yet ready to confront the United States directly, Tecumseh's primary adversaries were initially the Native American leaders who had signed the treaty, and he threatened to kill them all.
