The Percheron breed originated in France, taking its name from the former Perche province. Its exact origins are unknown, and several theories have been put forth as to the ancestors of the breed. These theories include the Percheron originating variously from Arabian stallions brought to the area by 8th century Muslim invaders, Moorish cavalry horses from the Battle of Poitiers and Boulonnais horses used by Caesars legions. It is known that much Arabian, Oriental and Spanish blood was added during the breed's history.
