Heavy breed of draft horse that originated in France's Perche region. The breed probably stems from the medieval Flemish great horse, which was modified by Oriental and draft-type blood to produce animals for heavy farm work. Percherons became popular in the U.S. in the 1850s and influenced U.S. agriculture more than any other draft breed. They average 16–17 hands (64–68 in. [163–173 cm]) high and weigh 1,900–2,100 lb (860–950 kg). Common colours are black and gray. Agile and energetic for their size, they have a mild disposition.
