The Western is a genre literature devoted to telling stories set primarily in the latter half of the 19th century in the American Old West, hence the name. Some Westerns are set as early as the Battle of the Alamo in 1836. Westerns often portray how desolate and hard life was for frontier families. These families are faced with change that would severely alter their way of life. This may be depicted by showing conflict between natives and settlers or U.S. Cavalry or between cattle ranchers and farmers, or by showing ranchers being threatened by the onset of the Industrial Revolution.
