c.1300, from Old French joustes, from joster (see joust (v.)). The sport was popular with Anglo-Norman knights.
These early tournaments were very rough affairs, in every sense, quite unlike the chivalrous contests of later days; the rival parties fought in groups, and it was considered not only fair but commendable to hold off until you saw some of your adversaries getting tired and then to join in the attack on them; the object was not to break a lance in the most approved style, but frankly to disable as many opponents as possible for the sake of obtaining their horses, arms, and ransoms.
