Periodization
Others, including the Library of Congress and the University of Oxford, often cite differing points reaching into the early 1900s; typically within the first two decades before American entry into World War I. A period known as "The Western Civil War of Incorporation" lasted from the 1850s to 1919. This period includes historical events synonymous with the archetypical Old West or "Wild West" such as violent conflict arising from encroaching settlement into frontier land, the removal and assimilation of natives, consolidation of property to large corporations and government, vigilantism, and the attempted enforcement of laws upon outlaws.
