The First Men in the Moon is a 1901 scientific romance novel by the British author H. G. Wells. The novel tells the story of a journey to the moon undertaken by the two main protagonists, the impoverished businessman Mr Bedford and the brilliant but eccentric scientist Dr. Cavor. On arrival, Bedford and Cavor find the moon inhabited by an extraterrestrial civilization the two refer to as "Selenites".
The novel can be read as a critique of prevailing political opinions of the period, particularly of imperialism. The theme of a clash between civilizations is reminiscent of Wells' earlier and more famous work, The War of the Worlds. As in The War of the Worlds, it is hinted that the non-human civilization presented might reflect the way human society would develop in the far future. As such, the Selenite society depicted could be considered either a utopia or a dystopia, depending on which of its features one emphasizes.
