Heroic drama is a type of play popular during the Restoration era in England, distinguished by both its verse structure and its subject matter.
[1][2] The subgenre of heroic drama evolved through several works of the middle to later 1660s; John Dryden's The Indian Emperour (1665) and Roger Boyle's The Black Prince (1667) were key developments.
The story was that of the national foundation of Spain (and King Charles II was known to be fond of Spanish plays), and the hero, Almanzor, was a man of great martial prowess and temperament.
Other heroic dramatists were Nathaniel Lee (The Rival Queens) and Thomas Otway, whose Venice Preserv'd is a fine tragedy that transcends the usual limitations of the form.
There was little dramatic critical theory for him to appeal to, and the new rules brought over from France (particularly those of Corneille and Boileau) did not match English theatrical history or practice.
