Who were the important tribes during 19 century?

In the 19th century, several important tribes played significant roles in North American history, particularly in relation to westward expansion and conflicts with settlers. Notable among these were the Cherokee, who faced forced removal during the Trail of Tears; the Sioux, known for their resistance against U.S. government policies, especially during the Great Sioux War; and the Nez Perce, led by Chief Joseph, who famously attempted to escape to Canada. Other tribes like the Comanche and Apache were also influential, engaging in various battles and negotiations as settlers encroached on their lands.
