What was tecumseh's attitude toward the treaties previously negotiated between the united states and various indian tribes? how did he plan to prevent the expansion of white settlements?

Tecumseh regarded the treaties that had been previously negotiated between Native American tribes and the United States as illegitimate and against the interest of the Native Americans. Tecumseh sought to create a confederacy of Native American tribes to fight against the U.S. to prevent expansion of white settlements into Native American lands. Tecumseh also threatened to ally with the British against the United States which Tecumseh later did. Tecumseh ultimately died during this conflict and the British-Native American alliance was defeated.
