Jesters were entertainers in medieval courts, known for their humor and wit. They often wore colorful costumes and distinctive hats with bells, allowing them to stand out. Their role was to amuse royalty and guests through jokes, storytelling, and physical comedy, often using satire to comment on social and political issues. In addition to providing entertainment, jesters had a unique position in the court. They could speak freely and critique nobles without fear of punishment, making them valuable for their insight. Famous jesters, like Court Jester Feste from Shakespeare's Twelfth Night, exemplify the blend of humor and wisdom that characterized this role.
