Gilbert and Sullivan opera is a form of musical theatre that originated in the late 19th century. Two of the most famous works are Iolanthe (8 letters) and PATIENCE (8 letters). Iolanthe is a satire of British politics and society, while PATIENCE is a parody of the aesthetic movement. Ruddigore (9 letters) is another popular Gilbert and Sullivan opera, which is a comic opera about a cursed family of aristocrats.
