Why did tecumseh have difficulty uniting the other native americans to resist the expansion of white people on their lands

By the early 19th century, many Shawnee and other Ohio Valley Indians were becoming increasingly dependent on trading with the Americans for guns, cloth, and metal goods. Tecumseh spoke out against such dependence and called for a return to traditional Indian ways

That’s to funny! lol

They had strained relationships with colonists but good relationships with american indians
