Steampunk City

In general, the category includes any recent science fiction that takes place in a recognizable historical period (sometimes an alternate history version of an actual historical period) where the Industrial Revolution has already begun but electricity is not yet widespread, with an emphasis on steam- or spring-propelled gadgets. The most common historical steampunk settings are the Victorian and Edwardian eras, though some in this "Victorian steampunk" category can go as early as the beginning of the Industrial Revolution. Some examples of this type include the novel The Difference Engine, the comic book series League of Extraordinary Gentlemen, the Disney animated film Atlantis: The Lost Empire, and the roleplaying game Space: 1889. Some, such as the comic series Girl Genius, have their own unique times and places despite partaking heavily of the flavor of historic times and settings.
Karel Zeman's film The Fabulous World of Jules Verne from 1958 is a very early example of cinematic steampunk. Based on Jules Verne novels, Zeman's film imagines a past based on those novels which never was. Other early examples of historical steampunk in cinema include Hayao Miyazaki's anime films such as Laputa: Castle in the Sky (1986).
Historical steampunk usually leans more towards science fiction than fantasy, but there have been a number of historical steampunk stories that incorporated magical elements as well. For example, Morlock Night by K. W. Jeter revolves around an attempt by the wizard Merlin to raise King Arthur to save the Britain of 1892 from an invasion of Morlocks from the future. The Anubis Gates by Tim Powers involves a cabal of magicians among the beggars and thieves of the early 19th century London underworld.
Paul Guinan’s Boilerplate, the biography of a robot in the late 19th century, began as a website that garnered international press coverage when people began believing that Photoshop images of the robot with historic personages were real. The site was adapted into an illustrated hardbound book Boilerplate: History’s Mechanical Marvel, and published by Abrams in October 2009. Because the story was not set in an alternate history, and in fact contained accurate information about the Victorian era, some booksellers referred to the tome as "historical steampunk".
