[1] The breed is sometimes erroneously referred to as "Mellerauds", notably by M. Cardini, who also claims (incorrectly) that Merlerault horses were once raised semi-wild in the woods.

[2][3] A breeding tradition has existed there for centuries,[4] with secular and religious guilds establishing stud farms as early as the Middle Ages.

Maximilien de Béthune, Duke of Sully, designated the Le Merlerault region as Normandy's horse production center;[2][7] this first stud farm was replaced in 1730 by the Haras du Pin.

[4] The Merlerault is an elegant half-breed[9] of medium size, with a square head on a well-set neck.

[10] The hocks may lack sharpness, and the animal is lightly built, with broad shoulders, agility, and speed.
