The "Wild West" refers to the period in American history during the late 19th century, roughly from the 1860s to the 1890s. This era is characterized by westward expansion, where settlers moved into territories that were largely uninhabited or occupied by Indigenous peoples. The discovery of gold and other resources led to rapid population growth and the establishment of towns, often marked by lawlessness and conflict. Life in the Wild West was often rugged and challenging. Cowboys, known for their cattle herding skills, played a significant role in this culture, while figures like Billy the Kid and Wild Bill Hickok became famous for their exploits. The era also saw the construction of the Transcontinental Railroad, which connected the East and West, facilitating travel and trade.
