Steampunk is a sub-genre of science fiction that typically features steam-powered machinery inspired by industrialised Western civilisation during the 19th century. Steampunk works are often set in an alternative history of the 19th century's British Victorian era or American "Wild West", in a post-apocalyptic future during which steam power has regained mainstream use, or in a fantasy world that similarly employs steam power.
