some southerners felt that confiscating property violated the constitution
Tecumseh did not believe Harrison when he said he was the end of the authority. He did not think the claims he made were legitimate ones.
Tecumseh was a very significant Native American who gave his life for what he believed. He knew that the Americans were a tremendous threat to all Indian tribes, and realized that the Indians would be destroyed one by one if not united. Tecumseh created a confederation of thirty-two tribes in hopes that the Americans would recognize their borders and thus put a halt to westward expansion. His confederation may have succeeded if it were not for the mistakes made by his brother, Laulewasika, the Americans violent actions towards the Indian tribes, and the unwillingness of the different tribes to cooperate. Tecumseh was born in March of 1768. His real name was Tecumtha, which meant "panther lying in wait," but to the white men he was called Tecumseh which stood for "shooting star."
The short answer...
The White man was selling off the Indian territories. There were some tribes that were selling their land to the White armies and not all the Native Americans agreed it was theirs to give. The land didnt belong to one tribe or another, and you can't sell land that isn't yours. This was going on for awhile and Tecumseh along with other Indians decided that it was time to fight for the land that was rightfully theirs. So he banded together other Indian nations to unite against the Westward expansion which was pushing the Indians out of their land.
