Minstrels performed songs which told stories of distant places or of existing or imaginary historical events. Although minstrels created their own tales, often they would memorize and embellish the works of others. Frequently they were retained by royalty and high society. As the courts became more sophisticated, minstrels were eventually replaced at court by the troubadours, and many became wandering minstrels, performing in the streets; a decline in their popularity began in the late 15th century. Minstrels fed into later traditions of travelling entertainers, which continued to be moderately strong into the early 20th century, and which has some continuity in the form of today's buskers or street musicians.
