So if I were so inclined, how should I go about reading "the story of Battletech"? I see that CGL has
some introductory PDFs, but then what after that? I suppose it would be some series of sourcebooks, but there's a whole lot to choose from over decades of publication, and I don't know whether some might be rendered outdated by newer editions or retcons. And what about an introductory novel for flavor? Seems like CGL recommends the Warrior Trilogy.
The quick and dirty history of BattleTech. Grab a cup of your favorite drink and settle in.
Man develops the JumpShip which allows us to leave Terra and journey to the stars. After a while we develop six major Inner Sphere states and four major Periphery states and because of distances we also bring back nobility. We have the Terran Hegemony (right in the center, House Cameron), The Draconis Combine (Northeast part of the Inner Sphere and feudal Japan LARPers, House Kurita), the Federated Suns (Southeast and King Arthur meets the Sun King's court, House Davion), the Capellan Confederation (South and more or less Communists with a whole bunch of Russian and Chinese influence, House Liao), the Free Worlds League (Southwest, a parliamentary democracy run by a handful of larger provinces whose favorite activity is fighting civil wars, also super merchants, House Marik), and the Lyran Commonwealth (Northwest, also super merchants, a lot of German and Scots-Irish, House Steiner). In the Periphery we have the Outworlds Alliance (East and love aerospace warfare and basically just want to be left alone and insignificant enough to be ignored, House Avellar), the Taurian Concordat (South-southeast, paranoid and hate the Federated Suns, House Calderon), the Magestracy of Canopus (South-southwest, Space Las Vegas, House Centralla), and the Rim World Republic (Northwest, kind of like ancient Greece in space, House Amaris).
Humans being humans, we decide that war is better than diplomacy so long as we treat it like a game with a bunch of rules instead of brutal slugfests. That's the Age of War. It's also when we develop the BattleMech, 40 foot tall big stompy robots. That's from about 2400-2550.
The Age of War was fun and all, but Ian Cameron thinks there has to be another way. So he sets about convincing the other house lords to set up a humanity-wide superstate called the Star League. Naturally, House Cameron will run it. After some arm-twisting, trade agreements, and backroom dealmaking, he gets what he wants. The Star League is born in 2570 and peace is here. But there's one catch: The Periphery states say "thanks, but no thanks." This goes over about as well as you would think and we have the Reunification War, because Terra knows best and the Periphery is joining by hook or by crook. Troops are sent in, the war is expected to be over before the leaves fall. In the end it takes 20 years and millions of dead civilians and troopers before the campaign is over. But the Periperhy states are brought to heel.
So now we have the Golden Age of Humanity. There are good leaders, bad leaders, almost wars, political intrigues, and all the things humans love to do to each other over the next 170 years. Then in 2751 Simon Cameron was totally not assassinated leaving his eight year old son Richard as First Lord and the commanding general of the Star League Defense Force, Aleksandr Kerensky, as his regent. He tries to be a good protector for the boy, but the Periphery states are getting uppity and sooner or later he is going to have to show up and lay down the law and so he's too busy to do much with the kid. Meanwhile, the leader of the Rim World Republic, Stefan Amaris, gets a little too chummy with Richard. Of course, stuff happens, war breaks out, the SLDF and Kerensky are stuck in the Peripehry, and Amaris throws a coup and kills every member of the Cameron family. We're up to 2766.
Amaris takes over the entire Terran Hegmony, Kerensky regroups in the Rim Worlds Republic and fights a very bloody war against Amaris and his troops while the other House Lords sit on the sidelines. At the end of it, Kerensky and the SLDF wins, Amaris and his family are shot, and the House Lords decide Kerensky will not be the next First Lord and fire him. They each want the job and about the only thing they do agree on is reestablishing the HPG network (Hyperpulse Generator, the way interstellar communications are handled) under Jerome Blake. Kerensky decides to take what's left of the SLDF out of the equation, and they leave into the unknown. The Star League is officially dissolved in 2780 and the Inner Sphere powers immediately grab what worlds of the Terran Hegemony they can and then fight amongst themselves for the top spot.
These are the Succession Wars. The first two smash humanity back technologically and the third just peters out. By 3025 we're still producing stuff like BattleMechs and Jumpships, but all the advanced tech of the Star League is long gone and attrition is killing off what battles and raids don't. But the current leader of the Lyrans, Katrina Steiner, and Hanse Davion enter into an agreement. He's in his 40s abut he'll marry her daughter as soon as she turns 18 in 2028.
