Where did Mini horse come from

The miniature horse in America is traced back as far as 1888, with notoriety as a breed not becoming too popular until the 1960′s. There are 2 registries, the original one being the American Miniature Horse Registry, established in 1971. They have two divisions, A – horses that measure 34 inches and under, and the B division, that measures from over 34 inches up to 38 inches, the maximum height allowable. The other well-known registry is the American Miniature Horse Association, that was established in 1978. They only register horses that are 34 inches and under.
