A courser is a swift and strong horse, frequently used during the Middle Ages as a warhorse. It was ridden by knights and men-at-arms. Etymology Coursers are commonly believed to be named for their running gait, (from Old French cours, 'to run'). However, the word possibly derived from the Italian corsiero, meaning 'battle horse'. Coursers in warfare The courser was more common than the destrier, and preferred for battle as they were light, fast and strong. They were valuable horses, but less expensive than the highly prized destrier. Another horse commonly ridden during war was the rouncey, an all-purpose horse. Other uses Coursers were also used occasionally for hunting. See also Horses in the Middle Ages Notes and references Warfare of the Middle Ages Warhorses Types of horse
