The United Planets, founded sometime before or during the 25th century, was an intergalactic republic mainly located in the Milky Way Galaxy, although there were a considerable number of other member planets in other galaxies, at least this was the case by the 30th century.
By the 2990s the United Planets was in a state of financial ruin, and it eventually collapsed. By the year 3000, it appears that it longer existed. It is unknown if the United Planets resurfaced after that.
