The unique skills of the cowboys are highlighted in the rodeo. It began in an organized fashion in the West in the 1880s, when several Western cities followed up on touring Wild West shows and organized celebrations that included rodeo activities. The establishment of major cowboy competitions in the East in the 1920s led to the growth of rodeo sports. Trail cowboys who were also known as gunfighters like John Wesley Hardin, Luke Short and others, were known for their prowess, speed and skill with their pistols and other firearms. Their violent escapades and reputations morphed over time into the stereotypical image of violence endured by the "cowboy hero".

Historiography Scores of Turner students became professors in history departments in the western states and taught courses on the frontier. Scholars have debunked many of the myths of the frontier, but they nevertheless live on in community traditions, folklore, and fiction. In the 1970s a historiographical range war broke out between the traditional frontier studies, which stress the influence of the frontier on all of American history and culture, and the "New Western History" which narrows the geographical and time framework to concentrate on the trans-Mississippi West after 1850. It avoids the word "frontier" and stresses cultural interaction between white culture and groups such as Natives and Hispanics. History professor William Weeks of the University of San Diego argues that in this "New Western History" approach: However, by 2005, Aron
