Oklahoma is a state rich in lawmen and outlaw history, truly the last bastion of the "Old West." The state has a tradition of banditry dating back to the time of the Indian Territory. The following account presents a collection of rare photographs, biographical sketches, and true stories offered in chronological order dealing with the epic battle between the forces of law and order and wrongdoers taking place in a geographic area encompassing the modern state of Oklahoma. This narrative, which represents nearly ten years of research, is presented in two-part form within a single volume. Part I covers the period of 1875-1919, chronicling events taken from the Indian and Oklahoma Territories to statehood and beyond, while Part II covers the period 1920-1941. This work does not represent an attempt to tell a complete history of lawmen and outlaws in Oklahoma. It is merely offered as a series of prime examples of the genre.
