The Cheyenne Indians: Their History and Their Ways of Life is a classic ethnography, originally published in 1928, that grew out of George Bird Grinnell's long acquaintance with the Cheyennes. Volume I looks at the tribe's early history and migrations, customs, domestic life, social organization, hunting, amusements, and government. In a second volume, Grinnell would consider its warmaking and warrior societies, healing practices and responses to European diseases, religious beliefs and rituals, and legends and prophecies surrounding the culture hero Sweet Medicine.
