The Commonwealth consists of the member nations of the former British Commonwealth, and their colonies. The are coalition of nations and worlds that have bonded together in order to maintain status as a major interstellar power that controls many worlds. It is the last true national alliance of any type in existance in 2260.
It is by no means an Empire of any type. There are still national rivalaries among the members of the Commonwealth, and not everyone plays nicely at all times.
