Leonard Arrington, who died in 1999, is considered by most, if not all, serious scholars of Mormon and western history as the single most important figure to write on LDS history. Great Basin Kingdom is perhaps his greatest work. A classic in Mormon studies and western history, Great Basin Kingdom offers insights into the 'underdeveloped' American economy, a comprehensive treatment of one of the few native American religious movements, and detailed, exciting stories from little-known phases of Mormon and American history. This edition includes thirty new pictures and an introduction by Ronald W. Walker that provides a brief biography of Arrington, as well as the history of the work, its place in Mormon and western historiography, and its lasting impact.
