Actually, a working type thing. Since we're already delving into ancient Terran history (the U War, which is not canon), might as well try doing something with the Vasudans.
Let's start with what we know of the Vasudans.
1) They're an Empire, ruled by an Emperor.
2) They're homeworld is a desert that was barely habitable in the first place.
3) Technolgoically, they're on par with the Terrans.
4) They're very like Terrans in many ways.
5) They're religious.
6) They had a parliament.
7) Said parliament was dissolved by the Emperor.
8) The Imperial government has existed for nearly 10,000 years.
9) Vasudan tactical doctrine is willing to sacrifice power for volume (the Mekhu).
10) Despite being woefully inferior, the Vasudans continued to use the Anubis fighter for years on the grounds that it was "cheap to produce."
11) Vasuda Prime is intensly resource poor.
Okay, that's enough. Not all of these will come into play in this thing, but they might.
Let's start with the age of the Empire. 10,000 years is a long time, a very long time, so we can safely assume that it has not ruled the whole of Vasuda for that entire time. There is no evidence to establish when the Vasudan parliament was created, however given that the Emperor was able to effectivily dissolve it, one could say that it probably wasn't very long before the 14 Year War, at most two or three generations. The reasoning here is that if Khoson (or however you spell his name) did not have the idea in his head that he could be absolute ruler of the Empire, say from hundreds of years of being the way things are, he might never have even considered dissolving it. However, if his grandfather had been an absolute ruler, he might easily approve of the idea. So the parliament was likely formed in the recent past, perhaps two generations prior to Khoson taking the throne. We're looking at less than one hundred years prior to the war.
With that in mind, let's explore a little about how the Vasudans likely expanded from Vasuda. First, the world they live on is resource poor, especially when it comes to water. This likely kept the population of the planet in check, making it easier for one Emperor to rule it all (backing the idea that parliament is a recent creation). Now, what happens if, say the government loops a comet, with its vast resources of ice, into orbit. The price of water drops, and the population explodes. An exploding population without an exploding availability of jobs leads to poverty.
Poverty plus religious nature does not necessarily lead to religious uprisings, but it could. Vasudan tactical doctrine, which dictates volume over power, seems to indicate that it did. After all, would you rather a big gun that would insta kill one enemy every second, or a small gun that would knock down 10 every second, when a hoard of religious nutjobs willing to die for their cause come running at you?
Okay, now what's the Emperor to do with all these people he never had to deal with before. Artificially raising the price of water might work, but that could kill millions. More humane solution: Get them off the planet. Now there is no evidence to say that the Emperor was humane except for the fact that there still is an Empire and not a smoldering pit of what was once a race.
Now, this is all before subspace (ancient, ancient history), but it sets up what happens next. With the limits of light speed, the Emperor's absolute rule no longer applys to the distant colonies, so they're ruled by governers. NOTE: The Emperor, with even our level of technology, could easily rule the entire planet of Vasuda. Okay, so the governers kind of get used to their remote status, the ability to rule themselves if you will.
Then subspace is discovered. While I can't argue this with any backing, I suspect the Vasudans might have discovered inter subspace with intra. At the moment that's neither here nor there, just my thought on that. It does, however, make one wonder why they hadn't (according to my 14 Year War timeline) discovered Antares earlier. My only explination is that the node to Antares is way out there, farther than most of the Vasuda colonies, and thus just plain missed.
With subspace, any absolute ruler worth his salt would start pushing for greater control over the far flung colonies, which they probably don't like. Relativily independent colonies plus new technology plus absolute ruler trying to use technology to gain more control over colonies equals civil war.
Likely, the colonies formed the parliament and began waging war against the Emperor. Who knows how long this went for or how it went, but eventually the economy, which was already shaky to begin with, probably collapsed and forced both sides to the table. The result was a deal between the Emperor and the parliament which formed the Parliamentary Vasudan Empire (or the other way around if you like, both are correct).
Now, given that the Emperor was able to later dissolve the parliament, it must be reasonable to assume that the power was divided more or less equally between the two parties. A shrewd ruler could, with a little positioning, lead the Vasudan people as a whole to believe that 14 years of warfare and losing the homeworld was the result of the parliament screwing up. This gave him enough leverage to remove parliament and reestablish absolute rule. In other words, the war was, in part, prolonged by one man (Vasudan) wanting to do things his way.
Well, that's a start. Any other opinions?
