Dracula is a gothic horror novel by Irish author Bram Stoker, famous for introducing the character of the vampire Count Dracula. The novel tells the story of Dracula's attempt to move from Transylvania to England so that he may find new blood and spread the undead curse, and of the battle between Dracula and a small group of men and women led by Professor Abraham Van Helsing. Dracula has been assigned to many literary genres including vampire literature, horror fiction, the gothic novel, and invasion literature. Stoker did not invent the vampire but he defined its modern form, and the novel has spawned numerous theatrical, film, and television interpretations. The story is told in epistolary format, as a series of letters, diary entries, newspaper articles, and ships' log entries, whose narrators are the novel's protagonists, and occasionally supplemented with newspaper clippings relating events not directly witnessed. The events portrayed in the novel take place chronologically and largely in England and Transylvania during the 1890s and all transpire within the same year between the 3rd of May and the 6th of November. A short note is located at the end of the final chapter written 7 years after the events outlined in the novel.
