The Federation (from Latin: foedus, gen.: foederis, "covenant"), is an interstellar state composed of 155 member states, colonies, protectorates, and other planetary governments unified under the goals of universal liberty, justice, equality, trade, exploration, scientific advancement, peace, and mutual protection. The most powerful state in local space, the Federation encompassed 8,000 light-years and is by far the largest state in the known Alpha and Beta Quadrants. The Federation, along with the Klingon Empire and the Romulan Star Empire, was one of the three traditional superpowers of known space. Unlike its traditional rivals who derive power from a single dominant species subjugating other races within the boundaries of their empire, the Federation's various Member States join willingly and are equals in the Federation's democratic society. The Federation's capital is Paris, Earth.
