In this question, I couldn't help but notice that the third starmap listed contains a territory called the "Martian Empire".

I could not find any reference to this Empire in Memory Alpha or Memory Beta via an (albeit) brief search, and I also noted that the other starmaps in that post do not have this space marked off, instead they have that area mostly empty, with a much smaller territory called the "Typhon Expanse" almost dead centre (Although this could be a result of the lossy 3d -> 2d conversion).

So, finally my questions:

What is the canonicity of this "Martian Empire"?

In what shows/books/etc. was it mentioned?

And when was (-will?) it supposed to have existed)?

    These seem like 3 different question, but given the dubious nature of canonicity, I think they're related enough to stand as one. (Just a pre-emptive thought.) Commented Feb 21, 2016 at 3:01
  • @MeatTrademark That's what I figured as well :)

There is no canonicity for a "Martian Empire" in Star Trek. The map that mentions it is a fan-produced work pertaining to an online sci-fi role-playing community.

There are absolutely no references to a "Martian Empire" in Alpha or Beta Star Trek material.

The map you have posted is not canon whatsoever. It is a fan-made map, designed by a member of the "Pheonix Command Group". It is an online role-playing community focused on science fiction works — mainly Star Trek but also some other franchises.

The history of the map is here:

The group's writings on a "Martian Empire" can be found here.

  • Ah, okay. I figured that it would be something like that. Thank you!
