Tenskwatawa (also called Tenskatawa, Tenskwatawah, Tensquatawa or Lalawethika) (January 1775 – November 1836) was a Native American religious and political leader of the Shawnee tribe, known as the Prophet or the Shawnee Prophet. He was a younger brother of Tecumseh, a leader of the Shawnee. In his early years, Tenskwatawa was given the name Lalawethika ("He Makes a Loud Noise" or "The Noise Maker"). Still, he changed it around 1805 and transformed himself from an unfortunate, alcoholic youth into an influential spiritual leader. Tenskwatawa denounced the Americans, calling them the offspring of the Evil Spirit, and led a purification movement that promoted unity among the Indigenous peoples of North America, rejected acculturation to the American way of life, and encouraged his followers to pursue traditional ways.
