Hola all! So, because I'm a dork and have a love of lists that almost matches that of our esteemed KRAD, I decided to go ahead and make a list of Federation Member States. I've been working on it for a while. Right now, the number clocks in at 153 -- just slightly below the 155 number established in Articles of the Federation. The list is based on a few key assumptions. To begin with, it assumes that if we see a member of the Federation Starfleet or an employee of the Federation government, then this person's species is probably a Federation Member unless otherwise stated. It's also based on the assumption that *most* of the Federation Member worlds listed in Star Trek: Star Charts are accurate. Because of some wildly contradictory information out there about the aliens seen on the Federation Council in ST4 that background material is in general not be accepted, and those species presumed to be from some of the numerous Federation Members that Star Charts establishes but does not assign a species to. I used as many worlds from the Memory Alpha and Beta resources as I could, and got much of my information from them. Special note on Rigel: This list presumes that the various worlds in the Rigel system, described as being unified as the United Rigel Colonies in Star Charts, are all part of a single Federation Member State, the United Rigel Colonies, commonly referred KEY AotF - Articles of the Federation TTN - Star Trek: Titan series STSC - Star Trek: Star Charts When known, formal names and notes are included.
