Galactic Terran Alliance
The Galactic Terran Alliance was an alliance formed by the human race after the unification of the peoples at Earth. Abbreviated as GTA. The space-based military wing of the GTA is known as the Galactic Terran Navy (GTN) but referenced as such only in the Freespace Reference Bible. The intelligence branch of the GTA is Galactic Terran Intelligence (GTI).
Speculation
Any info read here is not canon. The following section needs to be cleaned up to separate the facts from the interpretation.
The beginning
The Galactic Terran Alliance was formed in the first years of the age of space exploration, when the nations of the Earth have unified and formed an alliance. In the beginning, there were linguistic difficulties, but later, the English language later became a common language all through Terran space, even though not all GTA citizens spoke it as if it were their mothertongue, or did not speak it in a way that could be understood.
Initially, the alliance was focusing on economic and research factors, but later, with the discovery of Subspace, building, maintaining and developing a space navy was at hand.
Expansion
The Alliance spread their empire all through the Sol system, building shipyards, repair yards and other kind of factories or supply depots. By the end of the 23rd centaury, the GTA had already taken up the whole Sol system and also spread to Delta Serpentis and Beta Aquilae.
Wars
In 2320, the GTA first encountered the Vasudans. At the beginning, there was no armed conflict, the war only erupted in the year of 2321, when a Vasudan representative was murdered. Both sides mutually declared war on each other and the 14-Year War began.
After forteen year of seemingly endless war, when the Shivans destroyed both Vasudan and Terran targets, the two sides signed an armistice and turned against the cosmic destroyers. The most important war in the history of both species began.
Ross 128 had already been lost, Betelgeuse, Beta Cygni and Ribos also fell to the Shivans' superiority. When the Shivans took Antares, it became clear for the GTA that if the Vasuda system falls, they lost the Vasudans. In the effort to defend Vasuda from the mighty Shivan fleet, innumerable Terran pilots fell. Even after all the sacrifice both sides have taken, the SD Lucifer bombarded Vasuda Prime, killing billions of innocent Vasudans after only fourteen hours of ceaseless bombardment.
Sol was the next target of a Shivan attack. If it had not been for the Vasudan refugees who found the Ancient records, the Earth would have also been debilitated. Thankfully to the successful extraction of the Ancient data, the SD Lucifer was destroyed in the Subspace tunnel between Sol and Delta Serpentis, causing the jump node to collapse.
Although the Shivans were defeated and the Great War has come to an end, putting the dissolution of the long-living alliance was at hand.
Dissolution
In the year of 2345, the Terrans and Vasudans officially formed an alliance, called the Galactic Terran-Vasudan Alliance, causing the end of the Galactic Terran Alliance.
