The Dartmoor Pony was bred on the rough moorland of the Dartmoor Forest where the rivers Dart, Taw and Tavy meet. Very early this pony was linked with a mixture of breeds, which no longer exist. The earliest being the Old Devon Pack Horse, crossed between Exmoor and Dartmoor Pony blood and the Cornish Goonhilly Pony. Around the twelfth century oriental or eastern horses could have been interbred to the Dartmoor Pony line as well. The pony of this time could be described as ugly, but sure-footed, sturdy, a competent jumper and great for the mountainous terrain and wilds of the area. During the nineteenth century many breeds were crossed with the Dales Pony to improve the breed. These included trotting Roadsters, Welsh Ponies and Cobs, Exmoor Ponies, Arabians and small Thoroughbreds. Shetland Ponies were also crossed to try to create a pony for coal mining. The Dartmoor Pony became very close to extinction around the Second World War. The Pony and Riding Society, known today as the National Pony Society, is mostly responsible for saving this pony. Today the modern Dartmoor Pony is no longer considered ugly and far removed from the original ponies although still jumps well and is considered one of the most graceful riding ponies.
