Henry IV ( ) is an Italian play (Enrico IV) by Luigi Pirandello written in 1921 and premiered to general acclaim at the Teatro Manzoni in Milan on 24 February 1922. A study on madness with comic and tragic elements, it is about a man who believes himself to be Henry IV, Holy Roman Emperor. It has been translated into English by Tom Stoppard, among others. Rex Harrison starred in a noted British production which went to Broadway in 1973, though the Stoppard translation was not used in the production. In 2019, it was ranked by The Independent as one of the 40 greatest plays ever written. Plot overview An unnamed Italian aristocrat falls off his horse while playing the role of Henry IV during carnevale festivities, which take place annually before Lent. After he comes to, he believes himself to be Henry. For the next twenty years, his family, including his sister and now his nephew, Marchese Carlo Di Nolli, maintain an elaborate charade in a remote Umbrian villa, decorated to resemble Henry's imperial palace at Goslar and staffed with servants hired to play the roles of Henry's privy councillors and simulate the eleventh-century court. De Nolli's dying mother requests that he bring a doctor, Dionisio Genoni, who is referred to as the latest in a succession to try to cure Henry.
