Training a horse has changed its methods from years ago today with more systems but I believe our pioneers had better relationships cause they depended on horses more. Horses were their transportation and riders spent way more time on their backs cause they rode across country, hitched them to buggys, plowed fields and literally might as well have lived on their horses.

I believe the words of lots of older trainers in pioneer days systems worked just as well as some of those fancy trainers with dvd sets today. Since the invention of ebooks it is way easier to find and get rare training and horsemanship books to read that ever was before. Also shopping for training aids has because alot easier so you can just let your fingers do the walking.

There are lots of authors such as S, Sidney, Arthur Thomas, Forerich, Oliver Gleason, Allan Pope, Thorn and many more . You can find these Horse Training Ebooks here.

Horsemanship is the relationship of respect, communication and cooperation between the horse and his rider or handler. This differs from Equestrianism, or Equitation, which is judged on the rider's form, stylem and ability, without consideration to the horse's response to the rider, or the rider's response to the horse, or the horse's attitude.

Hints on Training your Horse

The form, proportions, muscular powers, and swillness of the horse, combined with its spirit, docility, and intelligence, expressly fit it for the use of man. It is alike serviceable for draft and the saddle. From its primeval nursery it has
radiated in all directions ; it has accompanied man in his wanderings over the world. To the industrious inhabitant of the thronged city, to the agriculturist, to the sportsman who follows the chase for pleasure, and to him who scours
the plains in quest of prey, a " mighty hunter before the Lord,'' this noble, beautiful, but too often ill-treated creature, is either important or essential. It performs the drudgery of toilsomeservitude ; it draws the peaceful plough, and
dashes on in battle amidst withering volleys of musketry and the clash of gleaming swords. Man owes a deep debt of gratitu ie to the horse, and is
bound to acknowledge his sense of its value by humanity and kindness. In its natural state, the horse is gregarious j and in domestication it exhibits the same propensity to associate with its fellows. In the field they herd together, form friendships, gambol with each other, and rush to the fence to see a strange horse in the road, saluting him with repeated neighings So decided
is the disposition of the horse to contract friendship, that, when others of its species are not accessible, it will attach itself to animals of a different species. Many instances of mutual attachment between dogs and horses have been
recorded. English Eclipse contracted a strong friendship with a sheep. When kindly used, the horse will demonstrate towards his master every mark of submissive attachment. There are, it is true, horses of a sullen, obstinate temper, which the kindest treatment will not conciliate; but these are exceptions to the general rule ; many horses, we may add, have their temper spoiled by injudicious or wanton severity, in which case it requires patience and perseverance to reclaim them; but almost universally, where kindness
is shown to the horse, his attachment will be secured. Find more on Horse Training Advice here
