Steampunk is a sub-genre of science fiction, alternate history, and speculative fiction. Specifically, steampunk involves an era or world where steam power is still widely used—usually the 19th century and often Victorian era Britain—that incorporates prominent elements of either science fiction or fantasy. Works of steampunk often feature anachronistic technology or futuristic innovations as Victorians may have envisioned them. Examples include H. G. Wells and Jules Verne
