The following passage was taken from the book "History of the Interstellar Community":
"History is a bewildering cauldron of incidents and events that we consider worth remembering, for whatever reason human minds cook up. These moments may or may not be what we consider to be true, be it interpreted by a human or an alien, by an Anglian or a Centralite, by a Bragulan or an Apexai, etc. One thing is clear, however: history studies what has happened, and it is the duty of the historian to present it as truthful and unbiased as possible. It is our hope that every one who reads this understands what we mean". -p. 7

2???-2500: The Age of Colonization
[Continuous]: Numerous Heim and hyper-capable colony expeditions spread from Earth and Nova Terra, mostly due to the Great Upheaval and its aftermath. For the first few centuries, most of these colonies were miniscule compared to the population and resources of the twin homeworlds, but over time would grow closer to parity as they expanded into interstellar powers in their own right.

Hephaestus Sterilized by Barbarians in a scorched earth campaign in 2580, killing some 1.63 billion people in the process. In the end the surviving barbarian forces collapse and leave RAR! sector. While central organization broke down, the fact that large numbers of Barbarians with sizable and heavily armed warships, large numbers of fighters and access to advanced ground equipment such as tanks and suits of power armor would lead to a rise in pirate activity around the galaxy for the next 60 years.
2590: The Battle on the Ice Planet. Bragulanity's first contact with humanity, armed colony ships from Earth and Nova Terra land on the minor moon Peypius and claim it for mankind. The native Bragulans there take exception to this, but the human colonists prove too well armed and shoot down their paleobragnukes with ease. However, the hero Prince Arglyksndir Bragsky detonates the nukes on the ice - breaking it and sending the humans and their landed ships plunging into the frigid water, where they are drowned to a man by the polar Bragulans. This first victory of freedom over human imperialism marks the beginning of Bragule's anti-humanism.
2706-2712: The Jaggan War begins when the Tyrant of Jagga invades Umerian space on a whirlwind campaign of looting and pillaging in early 2706. His boyz raided nearly every major Umerian world, causing great hardship, before the remnants of the Stellar Patrol succeed in checking his forces at New Princeton. After a five year hiatus in which both sides struggled to rebuild their forces, the Tyrant's asteroid flagship was destroyed by SpaceSec forces using what were to become the prototypes for future Umerian spinal particle-beam dreadnoughts. The Umerians went on to bombard Jagga intensely enough to render it incapable of sustaining even orkish life for a period of a few centuries, but the expense of the punitive expedition further hamstrung their economy, and prewar GDP and population weren't recovered until the late 28th century.

2900-2940s: The Great Crusade Begins, leading ultimately to the conquest of T'au, and an end to the decades long war between the Imperium and the Tau. By then most of the Tau race had been exterminated, at great cost to the Imperium.

Sidney Hank arranges an off-the-book exchange of POWs with Imperator Byzon: survivors from the surrendered Bragulan garrisons of Eta Bootis, Savoie and Formalhaut are swapped for human hostages and resistance fighters renditioned to the Star Empire's gulags, at a going rate of five humans for every bear. Tens of thousands of primarily Solarian citizens thus escape the misery of Bragulan prison camps. This is the only semi-official deal the Sovereignty has ever made with the Star Empire, and it very nearly ends in bloody murder as Byzon attempts to have Hank assassinated before he can leave mighty Bragule.
3120: The Time of Treason. Although this century of sedition, perfidity, mutiny and general civil unrest within the recently-formed Sovereignty in many ways started before its founding, it only truly heats up during the presidential elections of 3120.

The democrats ultimately win, and shape Solarian society into what it is today.
