A Progression of Training Horses

Some Notes:

"...they are not executed in accordance with specific principles, but depend solely on the physical energy of the rider and the forceful usage of physical strength. The rider practices these tricks only to dazzle people who lack knowledge in true equestrian art. The horse who is subjected to such violence initially obeys the unexpected demands, but soon wisens up and realizes his innate strength, and uses it entirely to oppose the force by suddenly throwing his head, neck, and body against it. One then wonders how the horse refuses to obey the rider in the simplest demands which it used to perform easily and willingly. Simply awakened from its surprise, it is now taking the initiative and remains resistant, perhaps forever." (1884; translation: T. Ritter)

"Among the public, a great majority of admirers celebrated the successes of the master with a truly feverish enthusiasm, but the 'experts', on the other hand, were almost exclusively on the side of his opponents." De Carpentry

The caricature of the Baucher system is the modern saddleseat riders who exagerate the elevation of the neck and place it’s lower edge behind the vertical for more front feet elevation. This excess shows the dangers of the system carried out to excess: the back hollows out and the hind legs no longer engage but lift up and down in a " hocky" action.

"...he most basic tenets of Baucher's beliefs were that (a) work at a standstill, through the use of flexions, would lift the horse's forehand, and that (b) this lifting of the forehand would cause the lowering of the haunches..." Jessica Jahiel

"Francois Baucher was not a nobleman nor an officer. He hadn't even learned to ride as a child, but came into the dressage world as an antrepreneur. He published "Méthode d'Equitation basée sur de nouveax Principes" in 1842, and created havoc. His methods were unorthodox, and he claimed to train a horse to high-school in a matter of months. He promised to make rideable horses that were untrainable, and all kinds of things that at the time seemed insulting to the few defenders of the old school, mostly a man named D'aure. A war broke out, and people took sides, and countless pamphlets were published where the two tried to grind the other to dust. There was a lot of politics involved, since D'aure was a nobleman and Baucher bourgeois. Also, Baucher rode at the circus to support himself, and this was popular with the general public. The uneducated on the matter were amazed.

The educated on the matter, foremost Louis Seeger also wrote and published several criticisms, most known is "An honest word to Germany's riders". The taking sides in this dispute has continued to this day, and some riders boast themselves to be "baucherists" while yet others use the expression derogatorily." Theresa Sandin
