Steampunk is a subgenre of science fiction that combines Victorian-era aesthetics with advanced technology powered by steam and clockwork mechanisms. It often features anachronistic inventions, such as airships, robots, and fantastical gadgets, all set in a world reminiscent of the 19th century. The style is characterized by its intricate designs, brass and copper materials, and a focus on craftsmanship. Steampunk influences various forms of media, including literature, fashion, and film, with notable works like The Difference Engine by William Gibson and The League of Extraordinary Gentlemen showcasing its unique blend of history and imagination.
