In the years following the American Civil War (1861–1865), Union Major General Lew Wallace served as a governor of the New Mexico territories; New Mexico not yet having been admitted as a state. His work there put him in contact with many of the characters that make up the Wild West’s near-mythic history, including Billy the Kid and Sheriff Pat Garrett. It was here that Wallace wrote what has been called by some “the most influential Christian book” of the 19th century, Ben-Hur: A Tale of the Christ.
