Steampunk features anachronistic technologies or retrofuturistic inventions as people in the 19th century might have envisioned them - distinguishing it from Neo-Victorianism - and is likewise rooted in the era's perspective on fashion, culture, architectural style, and art. Steampunk works are often set in an alternative history of the Victorian era or the American 'Wild West', where steam power remains in mainstream use, or in a fantasy world that similarly employs steam power. Steampunk is a subgenre of science fiction that incorporates retrofuturistic technology and aesthetics inspired by, but not limited to, 19th-century industrial steam-powered machinery.
