Western saddles are used for western riding and are the saddles used on working horses on cattle ranches throughout the United States, particularly in the west. They are the " cowboy" saddles familiar to movie viewers, rodeo fans, and those who have gone on trail rides at guest ranches. This saddle was designed to provide security and comfort to the rider when spending long hours on a horse, traveling over rugged terrain.
The design of the Western saddle derives from the saddles of the Mexican vaqueros - the early horse trainers and cattle handlers of Mexico and the American Southwest. It was developed for the purpose of working cattle across vast areas, and came from a combination of the saddles used in the two main styles of horseback riding then practiced in Spain — la jineta, the Moorish style which allowed great freedom of movement to the horse; and la estradiota, later la brida, the jousting style, which provided great security to the rider and strong control of the horse. A very functional item was also added: the saddle "horn." This style of saddle allowed vaqueros to control cattle by use of a rope around the neck of the animal, tied or dallied (wrapped without a knot) around the horn.
Today, although many Western riders have never roped a cow, the western saddle still features this historical element. (Some variations on the Western saddle design, such as those used in bronc riding, endurance riding and those made for the rapidly growing European market, do not have horns.) Another predecessor which may have contributed to the design of the Western saddle was the Spanish tree saddle, which was also influential in the design of the McClellan saddle of the American military, being used by all branches of the U.S. Army, but being particularly associated with the cavalry.
The Western saddle is designed to be comfortable when ridden in for many hours. Its history and purpose is to be a working tool for a cowboy who spends all day, every day, on horseback. For a beginning rider, the western saddle may give the impression of providing a more secure seat. However, this may be misleading; the horn is not meant to be a handle for the rider to hang onto, and the high cantle and heavy stirrups are not for forcing the rider into a rigid position. The development of an independent seat and hands is as critical for western riders as for English riders.
