When you cite a source for something, the source should justify the thing you're claiming. The relevant part of your post to the thread was that "The 19th century solution was to develop a bigger breed of horse." It is entirely contrary to what the Wikipedia article says - "The breed was established in the mid-eighteenth century, although its origins are much older".

(relatives have owned Friesian's and Clydesdale's and Norwegian Fjording Horses, but it's neither here nor there)
