<human>:  What is the historical context of the Battle of Little Bighorn?
<bot>: The Battle of Little Bighorn took place in 1876 in Montana and was the result of an armed conflict between the United States and several Native American tribes, primarily the Sioux and Cheyenne. It was a decisive victory for the Native American forces, who were led by the legendary Lakota war leader Sitting Bull. The battle is known for being the worst defeat for the U.S. Army in the Indian Wars and for being a major event in the life of Sitting Bull, who was later killed in 1890 during an attempt to arrest him by U.S. forces. The legacy of the battle has become an important part of the Native American narrative, and it is remembered as a symbol of Native American resistance against the U.S. government's policies of displacement and assimilation.
