Earth Alliance (Babylon 5) - Interstellar Alliance Membership

Interstellar Alliance Membership

President Luchenko and the newly reformed democratic government of the Earth Alliance joined the Interstellar Alliance in 2262 not long after its initial formation by John Sheridan and Delenn. The deal was that Earth would join if she allowed Mars' independence and withdrew all troops from the rebellious colonies that wished to remain independent after the civil war and Earth would receive artificial gravity technology from the Minbari upon entrance to the Alliance. By 2267 Earth had gained enough access to advanced technology to take part in a joint research and development program with the Minbari for a large scale tactical warship. The results were the Warlock class destroyer and the Victory class destroyer. The Victory class was fitted with highly advanced weapon and armor technologies and even a Vorlon primary weapon and Minbari stealth technology. The ship was over 2 miles long and highly maneuverable.

The actual status of Mars's independence isn't entirely clear: during the series Crusade it is described as "an independent member of the Earth Alliance".

In that year the Drakh attacked Earth, but their attack failed and their forces destroyed. However the Drakh were successful in starting a serious plague that would kill all humans on Earth within 5 years if not stopped. The Alliance then loaned out the use of the surviving Victory class prototype the IAS Excalibur to the Earth Alliance to help find a cure to the plague.

After Earth defeated the Drakh just outside of Earth space it is believed that EarthForce gained even more technology by so many Drakh ship debrees being destroyed and floating outside EarthSpace it gave Earth even more advance tech.

At the end of season four of Babylon 5 it was shown that Earth remained a member of the Interstellar Alliance for 500 years after its initial membership. However, Earth was on the brink of another civil war. Two camps had arisen, one supporting continued membership in the ISA and the other opposing it. The supporting faction had a early warning of a pre-emptive strike and in the ensuring conflict, Earth was devastated. This event was known as 'The Great Burn' and in the aftermath, civilization fell back into some akin to the Middle Ages. The ISA (initials of the Alliance) quietly sent Rangers (human ones) to slowly rebuild Earth and still make it look as if the old technologies were being rediscovered thus rebuilding confidence as well as the civilization. One million years after the foundation of the ISA, an Anla'shok (Ranger) is seen collecting the last of the records of Earth's history, proving that Earth did rejoin the Alliance. It was also shown that humanity had evolved into energy-based beings possessing technology similar in nature to the long vanished Vorlons, but their appearance is akin to the effect for Lorien.
