Map of Babylon 5 Galaxy
About the individual races in the Babylon 5 galaxy, which are known to the Earth Alliance, there is the following information:
Earth AllianceStill relatively new on the cosmic stage, the EA has (so the official abbreviation of the Earth Alliance) quickly advanced after first contact with the Centauri Republic where they first got the technical know-how to build jump gates and hyperspace engines enabling the to settle several colonies on other solar systems founded. Before encountering considerable problems with the Mars colony, which strives for independence.
The first contact with the Minbari Federation about ten years ago ended in a fiasco with the destruction of the Minbari ship, which resulted in a bitter war, in which the Earth forces was dominated by the far superior technology of the Minbari. In the final battle ("Battle of the Line") all the spaceships still available were pulled together to form a defensive perimeter around the Earth.
Just as the Minbari fleet was close to victory, the commander of a Starfury squadron called Jeffrey Sinclair ( the new commander of Babylon 5) tried to ram the nearest Minbari cruiser with his damaged fighter . Sinclair lost consciousness, but came 24 hours later regained consciousness and learned that the Minbari had surrendered themselves. No one knew why, but on Earth, the event was hailed as a great victory.
