Natural horsemanship is a collective term for a variety of horse training techniques which have seen rapid growth in popularity since the 1980s. The techniques vary in their precise tenets but generally share principles of developing a rapport with horses, using methods said to be derived from observation of the natural behavior of free-roaming horses and rejecting abusive training methods.
Natural horsemanship practitioners often describe their principles with evangelical zeal, describing the approach as being a radical departure from "traditional" techniques, which are often portrayed as being based in the use of unnecessary force. Users and practitioners tend to relate benefits both in relation to the quasi-scientific narrative of the ethology of horse behavior, viewing the horse as "other", but also to the idea of an anthropomorphic partnership. High-profile practitioners of natural horsemanship such as Monty Roberts and Pat Parelli market their methods and equipment extensively through books, television appearances, live shows and other media. The natural horsemanship movement is controversial in the mainstream equestrian community, with criticism leveled at practitioners on a number of levels, while natural horsemanship advocates in turn are highly critical of more traditional methods. Natural horsemanship promotors face criticism that their techniques are not "new" and are classical concepts that are simply renamed or repackaged in order to be able to sell products and merchandise.
The idea of working in sympathy with a horse in order to obtain cooperation is not new, with documented instances as far back as the two part treatise On Horsemanship by Xenophon (c. 430 – 354 BCE), which amongst other points, emphasized operant conditioning and emphasized reassurance over punishment. Later classical dressage practitioners such as Antoine de Pluvinel (1555–1620 CE) and François Robichon de La Guérinière (1688–1751) also emphasized gentle techniques. However, gentle training methods have always had to compete with harsher methods, which often appear to obtain faster, but less predictable results. In particular, the cowboy tradition of the American west, where the economics of needing to break large numbers of semi-feral horses in a short period of time led to the development of a number of harsh training methods that the natural horsemanship movement specifically has set out to replace.
