Powers of Darkness (Swedish Mörkrets makter) is an anonymous 1899 Swedish version of Bram Stoker’s 1897 novel Dracula, serialised in the newspaper Dagen and credited only to Bram Stoker and the still-unidentified "A—e."

It is a variant or adaptation rather than a direct translation, with added characters, new plot elements and significant differences from the original. It served as the basis of a shorter Icelandic version under the same title the following year (), which appeared as both a newspaper serial and a book.

Powers of Darkness

Powers downplays the vampirism of Stoker's novel and portrays Dracula primarily as the head of an international cult inspired by Social Darwinism, whose goal is elimination of the weakest and world domination by an elite.

Powers of Darkness

It was long assumed to have been based on lost or unpublished elements of Stoker's novel, such as preparatory notes and early drafts, but more recent research questions whether the translation is essentially a contemporary forgery, undertaken without Stoker's knowledge or consent. In the twenty-first century, new academic research and a renewed interest in the variant has led to several new translations and editions.

Story

Like its source novel, Powers of Darkness is a Gothic horror story about an Englishman visiting a Transylvanian castle to arrange its aristocratic owner’s purchase of a new property in England.

Differences between Dracula and Powers of Darkness

Here the visitor is Thomas, Tom or Tómas Harker, rather than Jonathan, and Dracula becomes Draculitz. The early part of the story is similar to Stoker’s, but where Stoker’s Dracula lives alone, in Powers he shares his castle with a deaf-mute housekeeper and a cult of ape-like followers. Harker follows the housekeeper to a secret basement "temple," where he discovers the cult practising ritual sacrifice, but Draculitz does not drink the blood of their female victims; nor does he shapeshift, as in the original novel. In both Nordic variants Harker encounters a beautiful blonde woman in the castle, rather than the three vampire sisters, or brides, of Stoker’s book, and while he is repulsed by them in Dracula, and relieved to be rescued by the Count's interruption, in Powers he is attracted to her and continues secretly to meet with her, in disobedience of his host's instructions.

Once he has arrived in England, Draculitz appears often in public, chatting pleasantly with Mina (here called Wilma or Vilma) and Lucy (called Western rather than Westenra) in the churchyard at Whitby, visiting Lucy when she is sick, and hosting a grand party with an international guest list at Carfax in London; Stoker's Dracula remained mostly in the shadows. Draculitz does not attack Mina, instead, she joins Hawkins and two new characters—the detectives Edward Tellet and Barrington Jones—and together they take their investigation to Transylvania and Castle Dracula, assisted by the Hungarian Secret Police en route. Unlike in Dracula, Van Helsing and his allies remain in England, where they kill Draculitz on Mina and her party's return.

Other new characters include Mina's uncle Morton and aristocrats called Prince Koromezzo, Countess Ida Varkony and Madame Saint Amand. The character of Renfield is not found in either Nordic version. Other original characters remain intact and are even among the vampires' victims: Holmwood and Seward die after falling prey to Lucy and Countess Vàrkony, respectively.

Reviewers and scholars alike have noted the more obvious eroticism of the Swedish and Icelandic Draculas: in the Guardian, critic Colin Fleming wrote that where Stoker's sexual metaphors "serve deeper, dark concepts", Makt Myrkranna "could have had the subtitle Lust in a Cape"; he notes Draculitz's preoccupation with female bosoms.

Social Darwinism and the Fin de Siècle

Draculitz not only has charge of the cult that gathers in his castle, but is known to correspond with international leaders, including English politicians and aristocrats, to engineer world domination. Several times he says that 'the world belongs to the strong' and protests that members of the elite have been suppressed by the majority for too long; his movement is growing, however, and will take over the world. His views reflect Social Darwinism, 'survival of the fittest' and the ideas of philosophers such as Nietzsche, as the growing fascist movement in Europe would increasingly interpret—or misinterpret—them.
