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 mammalian Humans of the planet Earth and the insectoid Thranx which 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.
