The Humanx Commonwealth is a fictional interstellar ethical/political entity featured in the science fiction novels of Alan Dean Foster.[1][2] The Commonwealth takes its name from its two major sapient species, who jointly inhabit Commonwealth planets and administer both the political and religious/ethical aspects. They are the humans of the planet Earth and the insectoid Thranx who dwell upon Hivehom. The Commonwealth is described as a progressive, well-intentioned liberal democracy spanning many star systems, and is somewhat similar to the United Federation of Planets from Star Trek. The Humanx Commonwealth is notable for its portrayal of a human–alien relationship that is not just mutually beneficial but symbiotic, allowing an amalgamation of the two species.
In 1987, Steve Jackson Games published the GURPS Humanx sourcebook for their GURPS roleplaying game. Scheduled for 2023, Battlefield Press International will be releasing a new game for popular RPG systems.
