In my science fiction novel there is one, loosely connected government that controls certain aspects of the galaxy. It is inter-system and inter-species in its makeup and who it governs. The thing is, outside organizations are very influential on officials in the government; part of the reason for the sub-plot political discourse that occurs in the background of the main action. What sort of government would this be most effective in? I don't want to go with empire/totalitarian because that reeks of "evil" to most audiences, and would ring a bell of alarm to anyone. I don't really want to go with a republic, because that's what most science fiction series use, and the political controversy isn't the main focus of the story. It has minor involvement with the plot, though. I was thinking a confederacy/commonwealth. It would make sense, and help with things on a distance scale since star systems or planets can have some power over themselves. But I don't want it to the degree of each planet being separate from each other, politically speaking. In a commonwealth, don't the states make a majority of their own rules, but there are a few federal rules they accept as well? Is the power states>federal instead of the normal USA federal>states? Some good resources on the types of governments would be welcomed...Google isn't helping me much, except if I'm searching for a specific type. I want a link to somewhere that explains all types of governing bodies.
