By 1862, the Dakota were crowded into a small reservation along the Minnesota River. Times were hard and Indian families hungry. When the U.S. government broke its promises, some of the Dakota went to war against the farmers and towns. Many Dakota did not join in, but the fighting lasted six weeks and many people on both sides were killed or fled Minnesota. Afterwards the government forced most of the remaining Dakota to leave Minnesota. The Anishinabe stayed in northern Minnesota, and were not involved in the war.
