Aesthetically distinctive and magnificently expressive, steampunk is a subgenre of retrofuturistic science fiction featuring a society reliant on steam-powered technology. The visual flare of steampunk takes inspiration from the 19th-century Industrial Revolution, often incorporating both the technological merits and the socio-economic struggles of the time in its themes. Steampunk worlds took a different historical route from other science fiction narratives, where the use of steam engines became absolute.
