The Prisoner of Zenda (1894), by Anthony Hope, is an adventure novel in which the King of Ruritania is drugged on the eve of his coronation and thus is unable to attend the ceremony. Political forces within the realm are such that, in order for the king to retain the crown, his coronation must proceed. Fortuitously, an English gentleman on holiday in Ruritania who resembles the monarch is persuaded to act as his political decoy in an effort to save the unstable political situation of the interregnum.

The name of the villain in The Prisoner of Zenda, Rupert of Hentzau, is the title of the sequel novel, Rupert of Hentzau (1898), published four years later and included in some editions of The Prisoner of Zenda. The popularity of the novels inspired the Ruritanian romance genre of literature, film, and theatre that features stories set in a fictional country, usually in Central Europe and Eastern Europe, such as Ruritania, the Central European realm that named the genre, which includes the Graustark novels by George Barr McCutcheon.
