I figured a lot of newbies might like to know some of the lore behind the BattleTech franchise without having to browse Sarna randomly, given that you might not even know what you're looking for. This isn't a deep dive off the ladder, but rather a top-level overview of some of the more important things that happened.
Part 1: The Alliance and the Demarcation Declaration
Our story begins on a little blue planet called, in English, Earth. The primary point of divergence is in the 1980s, though it's not so major a diversion as other franchises. Rather, the Soviet Union did not fall, and the Cold War continued on until 2011, until a civil war broke out between a faction of liberal reformers and a faction of hardcore communist conservatives.
Obviously, the threat of Soviet nukes falling into rebel hands was not something any civilized nation desired, most prominently NATO. The US and its allies intervened on behalf of the liberals. They liberated Poland and Chekoslovakia and, victorious, divided the former Soviet Union into several nations (not along modern-day political boundaries either).
After this the victorious Allies looked at each other and nodded, realizing that mutually they were exponentially stronger than they were apart. So the EU decided to unify into the newly formed, much stronger, political entity of the Western Alliance. They invited the USA to join, and the USA hesitated, but then the Alliance threatened an embargo and the US decided to cut their losses and join.
Over the next few decades the Western Alliance expanded. After a brief standoff with China when Japan joined the Alliance that ended with China joining the Alliance but East Asia retaining some autonomy from the Alliance Parliament, the union had grown to the point where they could only rightfully call themselves the Terran Alliance, because of course Earth became Terra like every other 80s sci-fi franchise. The Alliance had previously been rather benevolent but with hegemony achieved it became much like any other nation.
Early in the 21st Century, two scientists, Thomas Kearny and Takayoshi Fuchida, posited that if you messed with the universe juuuust right you could create an instantaneous teleportation between two points of gravitational stability up to 30 lighttears large. Their peers regarded their theories as a great big joke and they were thrown into disgrace in their profession. Both died unvindicated- Kearny with nothing of note, Fuchida as the husband of a Katherine Kurita. Remember that last name (and yes the Kuritas are descended from the real-life Takeo Kurita who served in the Imperial Japanese Navy during WW2).
In the 21st Century scientists made discoveries of subatomic motion and they realized, pulling out the papers, that Kearny and Fuchida were right. After some tests through Project Deimos (the funding of which created considerable issues on Terra because poorer nations regarded it as a waste of funding), Kearny and Fuchida were vindicated and the Alliance sent a manned mission to Tau Ceti, where they discovered a planet so Earthlike that it was immediately named New Earth, and became the first interstellar colony (Mars and the Moon were both also colonized before this, as was Venus).
The first colonies were all founded by richer nation-states of the Alliance- European nations, the USA, and such. They picked the best of the litter. As the years wore down and colonization became more and more affordable more organizations and nations started establishing colonies under Alliance leadership. As their dependence on Terra decreased, the Alliance split into a two-party system: the Expansionists and the Liberals. The Expansionists were nationalists that had no qualms about military force to ensure Terra's leadership: the Liberals became more and more radicalized, as the Expansionists retained power.
Eventually, some colonies on the edge of Alliance space, which would later become divided into the Inner Sphere (the 5 Great Houses) and the Periphery (everything else) declared their independence. Eager to express their power, the Alliance Parliament, with the Expansionists still in power, sent the Alliance Global Militia's Colonial Marines to enforce Terra's will. They failed. Badly. Very badly.
So badly in fact that the Liberals were immediately swept into power.
They made one great big decision immediately: Terra had no right to dictate to the colonies. Any of them. In fact, if you were more than 1 JumpShip jump away from Terra, you were free. Good luck. You're not Terra's problem anymore.
Suddenly every world beyond a small bubble was independent of Terra. If they had wanted it or not.
That was the Demarcation Declaration, and it set the stage for the next era, the rise of the Great Houses and the Age of War.
