In three short words, steampunk is Victorian science fiction. Here “Victorian” is not meant to indicate a specific culture, but rather references a time period and an aesthetic: the industrialized 19th century. Historically, this period saw the development of many key aspects of the modern world (mechanized manufacturing, extensive urbanization, telecommunications, office life and mass-transit), and steampunk uses this existing technology and structure to imagine an even more advanced 19th century, often complete with Victorian-inspired wonders like steam-powered aircraft and mechanical computers.
