The music of the troubadours and trouvères was performed by minstrels called "joglars" (Occitan) or "jongleurs" (French). As early as 1321, the minstrels of Paris were formed into a guild. A guild of royal minstrels was organized in England in 1469. Minstrels were required to either join the guild or abstain from practising their craft. Some minstrels were retained by lords as jesters who, in some cases, also practised the art of juggling. Some were women or women who followed minstrels in their travels. Minstrels throughout Europe also employed trained animals, such as bears. Minstrels in Europe died out slowly, having gone nearly extinct by about 1700, although isolated individuals working in the tradition existed even into the early 19th century.
