List of Western subgenres
The Western is a genre set in the American frontier and commonly associated with folk tales of the Western United States, particularly the Southwestern United States, as well as Northern Mexico and Western Canada. It is commonly referred to as the "Old West" or the "Wild West" and depicted in Western media as a hostile, sparsely populated frontier in a state of near-total lawlessness patrolled by outlaws, sheriffs, and numerous other stock gunslinger characters.
