The Quarter Horse is declared to be the oldest North American breed and originated in the eastern states of the US. The settlers in the New World inherited much of its stock from the Spanish explorers and at this time a lot of that stock were Spanish horses (Andalusian, Barb, and Arabian). This stock was crossed with the native “running horses” that were imported from England in 1611 to Virginia and created what is now the Quarter Horse. This horse was chunky and compact with enormously muscled quarters. The Quarter Horses were used for work on the farm, rounding cattle, hauling, carriage pulling, and riding horses. These multipurpose horses were mostly valued for their ability to sprint over short distances from a standing start and by 1656 Quarter Horse racing in Virginia was popular. After the introduction of the Thoroughbred the Quarter Horse racing became less popular and the horses were used mostly in the west to be cow ponies. Today once again Quarter Horse racing has become popular with the prize money sometimes exceeding that of the Thoroughbred racing. This racing has increased the crossbreeding of the Quarter Horse to the Thoroughbred and thus detracting breed characteristics from its hindquarters. The Quarter Horse is perhaps the best cow pony in the world because of its speed, agility, and balance. The Quarter Horse excels as a trail riding mount and in rodeo classes. These horses can be found all over the world and in many countries including the UK. The largest Quarter Horse population besides in the US can be found in Australia. The Quarter Horse registry is the largest in the world with over 3 million entries.
