The Percheron is a breed of draft horse that originated in the Perche valley in northern France. Percherons are usually gray or black in color. They are well-muscled, and known for their intelligence and willingness to work. They were originally bred for use as a war horse. Over time, they began to be used for pulling stage coaches, and later for agriculture and hauling heavy goods. In the late 18th and early 19th centuries, Arabian blood was added to the breed. In the late 19th century, exports of Percherons from France to the United States and other countries rose exponentially.  In the 1930s, Percherons accounted for 70 percent of the draft horse population in the United States, but their numbers declined substantially after World War II. However, the population began to recover, and as of 2009, around 2,500 horses are registered annually in the United States alone. Today, the breed is still used extensively for draft work.  Percherons are used for forestry work and pulling carriages, as well as under saddle work, including competition in English riding disciplines such as show jumping.
