A jester was a historical entertainer, often found in royal courts during the Middle Ages and the Renaissance. They were known for their colorful costumes, witty humor, and ability to make people laugh. Jesters used satire and clever wordplay to comment on social and political issues, often providing a unique perspective that others could not. In addition to humor, jesters often performed tricks, juggling, and music. They were skilled in improvisation and could adapt their performances to suit the audience. Famous jesters, like Court Jester Feste from Shakespeare's play Twelfth Night, illustrate the important role they played in entertainment and commentary.
