Bulwer-Lytton wrote many other works, including "Vril: The Power of the Coming Race" (1871) which drew heavily on his interest in the occult and contributed to the early growth of the science fiction genre. Its story of a subterranean race waiting to reclaim the surface of the Earth is an early science fiction theme. The book popularised the Hollow Earth theory and may have inspired Nazi mysticism. His term "vril" lent its name to Bovril meat extract. The book was also the theme of a fundraising event held at the Royal Albert Hall in 1891, the Vril-Ya Bazaar and Fete. "Vril" has been adopted by theosophists and occultists since the 1870s and became closely associated with the ideas of an esoteric neo-Nazism after 1945.
