The theme was set in the American Old West in the second half of the 19th century and featured cowboys, outlaws, cavalry soldiers and native Americans. It was the first theme that introduced realistic fire arms (revolvers and rifles) that could also be found in the real world of today, while Pirates only featured antique weapons like muskets and flintlock pistols. It was also the first theme to introduce racial characteristics for minifigures. That being the printed head pieces for the indians.
