The Tempest is a play by William Shakespeare, estimated to have been written in 1610–11, (although some researchers have argued for an earlier dating). The play's protagonist is the banished sorcerer Prospero, rightful Duke of Milan, who initially uses his magical powers to punish his enemies when he raises a tempest that drives them ashore. The entire play takes place on an island under his control whose native inhabitants, Ariel and Caliban, respectively aid or hinder his work. While listed as a comedy when it was initially published in the First Folio of 1623, many modern editors have since re-labeled the play as one of Shakespeare's late romances.
