To the east were the Yuchi & Iroquoian Cherokee, divided along the Tennessee River. In the north-central region of the state were the Algonquian Cisca. They later moved northeast and merged with the Shawnee, but were briefly replaced with a second native nation known as the Maumee, or Mascouten which were driven south during the Beaver Wars (1640-1680) from southern Michigan. They later merged with the Miami of Indiana & were, once again, replaced by the Shawnee. The Shawnee controlled most of the Ohio River Region until the Shawnee Wars (1811-1813).
