===The [[Inner Sphere]]===
While other time periods might have better or more interesting rules, the most popular ruleset remains the eras between the Fourth Succession War (3028) to just before the Word of Blake Jihad (3067). This list of Inner Sphere factions covers those periods with the most prominent being the Great Houses in the Inner Sphere (a region within a 550 light year radius of Terra):

====[[Federated Suns]]====
Ruled by House Davion, the Federated Suns is feudal Space America or nepotistic Space UK. [[Lawful Good]], ruled by a Great House as inbred as any other is, and with all positions of power occupied by the same set of mostly blood-related elites. Without the blue blood, you're just a clever commoner. However, the Federated Suns isn't as stratified as the other Successor States, and it's easier for a common citizen to climb the ladders of wealth and power, which fuels an entrepreneurial society that is among the wealthiest in the Inner Sphere. They’re heroic defenders of freedom and democracy, provided you define “freedom and democracy” as “being ruled by the Federated Suns”. Their colors are red, white, and blue.  Something about that sounds strangely familiar...

Similar to [[Ultramarines|a certain faction in a certain other wargame]], the Federated Suns usually win most of their battles, and are usually presented as the good guys, drawing a lot of accusations of Mary Suehood.  Unfairly, though, as the FedSuns win so much due to wealth-fueled research and production. In other words, they work hard, do a good job, encourage businesses, and they get rewarded with victory. Unlike the Smurfs, however, the Federated Suns has actual flaws - their “democracy” is a rubber stamp, their rhetoric about freedom is mostly just an excuse to justify warmongering and imperialism, and they have such a staggering degree of wealth inequality that there are cases where the populations of multiple planets only have a single school to go between them. This means that the FedSuns attract two kinds of fans: twelve-year-olds who buy all the propaganda, and people who can appreciate playing a bunch of self-righteous, hypocritical jackasses. On the bright side, they do live up to the hype when it comes to individual liberties, and their rulers are genuinely competent and mostly don't dick them over.

Thanks to their great wealth, the Federated Suns can afford to fund actual scientific research in the form of the New Avalon Institute of Science, or Space MIT, and the Davions supported most of the tech development and recovery in the Inner Sphere prior to the Clan Invasion. They also got lucky when they found an ancient Star League library filled with various editions of tabletop wargame splatbooks. They are known to be the house that first heavily employed or utilized a lot of Clan personnel and technologies after the conclusion of the invasion.

The Federated Suns also kind of have a thing for autocannons. Think [[Space Wolves]] with wolves, or [[Orks]] with [[Dakka]], and you have an idea. If it does not have an autocannon on it the Suns will find a way to give it one, and if it does have an autocannon they find a way to upgrade it to a rotary autocannon. So if you like autocannons (and you should) this is the faction for you.

Prior to the Fourth Succession War, the Federated Suns and Lyran Commonwealth were united through marriage (technically the political union was a treaty and the marriage was out of love and had no impact on the nations' unification), forming the Federated Commonwealth, the largest and most powerful empire in the galaxy since the Star League. In order to bridge the distance between the two nations, however, the Federated Commonwealth had to conquer large swathes of the Capellan Confederation, which they did easily. However, only a few decades later the Commonwealth was broken up by the FedCom Civil War, when Katherine Steiner-Davion schemed to either take over the Commonwealth or secede the Lyran half of it because she was a royal bitch. She is commonly known as simply The Bitch by many fans. And her splitting of the FedCom is incredibly weird since her nobles were against her, her military mostly liked the advantages brought by the FedSuns, and her public liked the massive boosts in economy and technological progress. Oh, and she was rebel usurper and had no authority to do any of the things she did. So her successful secession doesn't make a lick of sense and you just kinda have to suck it up. And to top it off, she had her mother murdered out of greed. The FedSuns are currently getting kicked around by pretty much everybody during the Dark Age, primarily because the current head of the house, Caleb, is extremely paranoid and rather psychotic.Thankfully he got killed by the Kuritans with some insider help from Clan Snow Raven (in exchange for some buffer territory). Not so thankfully, his death also brought the destruction a major chunk of the Davions' regular armed forces concentrated on one planet while enabling the Kuritans to take over the capital. Kuritans being what they're like, they probably raped and tortured everyone they didn't murder and alongside their dogs. <strike>''Save us, Julian!''</strike>

====[[Lyran Commonwealth]]====
[[File:Steiner Assault.jpg|350px|right|thumb|A typical scene of a Lyran Archon wondering why their cousin has failed to relieve the Commonwealth alongside a bloody frontline against their enemies. They're likely either at a ball dance or planning a coup.]]
Space Germany with some Space Scotland and Space Scandinavia kicking around, the Lyran Commonwealth is the largest successor state and owns the most resource-rich planets in the Inner Sphere, making them an industrial and economic powerhouse. Their government was supposed to be modeled on ancient Athens, led by a council of nine Archons, but this did not work out ''at all'', and eventually Archon Robert Marsden decided he'd had enough of this shit and overthrew the other Archons in a military coup. The Marsdens were eventually replaced by the Steiners via marriage, who have ruled the Commonwealth to this day.

The Lyrans are rich. Really, really absurdly rich. The only reason they haven't conquered the Inner Sphere yet is that they prefer to put the relatives of rich businessmen in charge of their army rather than, y'know, actual soldiers, meaning a significant amount of Lyran officers are terrible at their job. There is at least one recorded case of the Lyran military starting a major interstellar war ''by accident''. Fortunately, since they're so rich, they're able to make up for their ludicrous incompetence with the biggest and heaviest weapons in the Inner Sphere. The joke goes that a typical Steiner scout lance consists of  four 100-ton '''''Atlas''''' 'Mechs (imagine a scout-recon team composed entirely of [[Warlord Battle Titan|Warlord Titans]] and you'll get the idea). Steiner forces tend to be big and slow, barely able to outmaneuver enemy fortresses. Of course, once they (eventually) get into range, you can kiss that fortress goodbye... And God-forbid you run into the rare Steiner commander who knows what they're doing. Ask the Clans at Tukayyid how that went for them.

Late in the Third Succession War, Archon Katrina Steiner shocked the entire Inner Sphere by actually calling for a peace treaty. Only Hanse Davion was at all interested, and he wound up marrying Katrina's daughter Melissa and uniting the two countries into one massive empire, the Federated Commonwealth (see above). Predictably, this Beauty-and-the-Geek romance started out exceedingly awesome then epically failed and it's back to single life for the too-pretty Steiners. They recently tried to have Clan Wolf migrate through their coreward territory to keep the Free Worlds League from reforming during the Dark Age while holding the transported civilian castes as insurance. The plan backfired with the Free Worlds League still reforming and Clan Wolf taking much of the coreward and middle territory in the Lyran Commonwealth to form the Wolf Empire. This, on top of a massive amount of civil unrest means the Lyrans are too busy with damage control from Wolf and Jade Falcon invasions along with internal rebellions to be a threat to anyone. The moral of the story is: don’t try to manipulate badasses who nearly conquered everyone without trying. They will fuck you up for it. Also, trying to hold civilians hostage against a culture that thinks civilians are barely human at all is pointless. It tends to go like "Okay, I'll kill a bunch of your people and conquer chunks of your territory". You threaten to kill the civilians and your enemy is totally incapable of understanding why they should care when they treat them as replaceable subjects instead of irreplaceable citizens. Come the rise of the ilClan on Terra and there’s a sudden power vacuum where the Jade Falcon occupation zone to the North use to be. This led to a massive Balkan-style disintegration of the said region alongside the Lyran’s northern provinces; many of resulting statelets are very ticked off at the Steiners for leaving them to rot. While Jade Falcons are barely around in the region, holdout territories and other Clans like the Hell’s Horses and Ghost Bears are eyeing the new buffer zone cautiously before seeking new planets to annex.

====[[Free Worlds League]]====
Taking elements from America, Yugoslavia, and Austria-Hungary (distinctions which grow less relevant with each passing day), the Free Worlds League is a federal democratic republic. No, really! They have a parliament and everything. Of course, the commander-in-chief of the Free Worlds League Military is always a member of House Marik because parliament doesn’t think anyone else can do the job, and the entire country has been operating under martial law “for the duration of the emergency” since the Star League broke up. But in principle, both democracy and federalism are alive and well in Marik space, making it impossible to get anything done. Think of the Free Worlds League as Space Holy Roman Empire due to regionalist nationalism. 

Everyone in the Free Worlds League hates everyone else in the Free Worlds League; the only thing keeping them together is mutual animosity to the Lyrans, Capellans, and Periphery bandits raiding their borders. After finding out that Captain-General Thomas Marik had been in hiding running the Word of Blake for decades and the guy they’d been taking their orders from all that time was actually just some hobo picked up off the street, they gave up on trying to make the thing work at all and collapsed. Which is a shame because fake Marik was actually one of the best Captain-Generals they ever had. After the Dark Age, said hobo’s daughter managed to put it back together again, which kind of makes you start to wonder about that whole “only the Mariks can handle the Captaincy-General” thing. Doesn't help that she had to make a deal with the Spirit Cat and Sea Fox clanners to cement the whole thing together as well as marrying the official Marik family's head.

The Free Worlds League Military is built around combined arms warfare, treating infantry, vehicles, and aerospace fighters as if they were just as useful as mechs. They also used to have the most LAMs back before [[squat|LAMs ceased to be a thing]]. They don’t get a lot of attention, since they’re far away from the FedSuns and the Clans and therefore don’t get involved in stories about factions the writers actually care about.  The constant in-fighting probably doesn't help.  That said, they most likely do enough to keep their jobs, which is probably good enough to satisfy the average Joe, who couldn't care less about political squabbles. Recent lore hints they’re probably at the forefront of the ilClan’s attention now due to Leaguers eager to reconquer their lost territory. Whether they get out of the border war in one piece is up for debate.

====[[Draconis Combine]]====
Ruled by House Kurita, the Draconis Combine is the obligatory Space Japan, in the sense that it is ''obligatory'' to be Japanese. It has large Arab and Scandinavian minorities who are legally required to be [[weeaboo]]s, with the country as a whole drawing on both the age of samurai and the militaristic Imperial Japan of the 1920s to 40s. The twelve-year-olds listed above, if they leave the FedSuns, will likely move to this weeaboo paradise with its delusional "fierce solo samurai warrior takes on all opponents Kurosawa Style"  appeal, not realizing that lone 'Mechs get [[rape|gang-banged]] by enemies who are teamed up like a pack of mechanical hyenas. Defended by weeaboos despite being responsible for the single most horrific massacre in human history during the First Succession War, or at the least, the only one anyone in and out of universe bothers to actually remember. For an alternate look into this supposed massacre, please read ''Did 52 million really die?''  In fact, they have a habit of doing this.  “We defeated the mercenaries on this planet who have nothing to do with the general populace.  Nuke everyone before we leave.  Why?  Uhhhh...do we really need a reason? <s>they’re not our enemies or anything, but [[Lulz|murder is fun]]</s> SCORCHED EARTH TACTICS! Preventing enemies from using the planet’s populace or resources against us is a valid strategy!”

Like everyone else in the Inner Sphere, the Draconis Combine is a warmongering, autocratic empire ruled with an iron fist that wants to take over the galaxy. Unlike everyone else in the Inner Sphere, they actually admit it. They're the only successor state that makes absolutely no pretenses of being a democracy, with the Coordinator of Worlds being treated as a divinely anointed absolute monarch who is the sole legitimate ruler of all humanity. They were the first to start shit after the Star League collapsed, with the Coordinator declaring himself the new First Lord and launching an invasion of the Federated Suns that eventually wound up getting him killed on Kentares IV, prompting his son to launch the aforementioned massacre. They've been the mortal enemies of the Federated Suns ever since.

Similar to the Davions and their love of autocannons and the Steiners and their love of everything heavy and assault, Kuritans are really, really into PPCs (Particle Projector Cannons), mainly because they're dirt poor and [[Lasgun]]s are cheaper than bullets. If there is a mech that can possibly mount a PPC, the Dracs will put one on it. For instance, see the ''Catapult'': a 65-ton long-range fire support 'Mech intended for indirect fire using the Long Range Missle (LRM) racks in its "ears". Almost every variant of the ''Catapult'' is centered around these LRM racks with a few minor backup weapons. They are a reliable, battle-tested design that no commander in their right mind would attempt to 'fix', because isn't broken... except in the eyes of House Kurita. Once the Combine got their hands on it those ears were replaced with two PPCs for direct fire support and two machine guns for <s>civilian massacres</s> INFANTRY DETERRENTS.  

Kuritans were also [[Fail|involved in the worst BattleTech novel ever written]], wherein a ship of theirs was lost in time and space, and [[what|found giant]], [[Kroot|alien, sentient chickens]]. Far Country is a [http://www.youtube.com/watch?v=U6zQ6ZqEqg0 Shamefur Dispray]! and pretty much serves as the only time aliens are actually mentioned in the BattleTech universe.

====[[Capellan Confederation]]====
Culturally, Space China and Space Russia. Politically, Space North Korea. The Confederation was originally founded when several minor states in the Capellan Zone who were sick of the Federated Suns trying to "liberate" them joined together, [[lolwut|bombed their own capital of Capella to make a point]], and fought the Davions off. Secure in this victory, they then proceeded to never win a war ever again.  Sounds like their rulers were evil after all.

Citizens of the Capellan Confederation enjoy probably the highest standard of living of any commoner in the Inner Sphere, with an extensive, cradle-to-grave welfare system and the best education and health care the state can provide. [[Grimdark|*Non*-citizens of the Capellan Confederation, known as "Servitors", are basically slaves.]] Becoming a citizen requires you to provide a certain amount of service to the state by the age of seventeen, and citizenship can be removed as punishment for disloyalty. Even those who aren't unfortunate enough to be Servitors basically have their lives decided for them by the Capellan caste system and the government's ability to tell them that they have to move to a new planet and take up a new career at any given moment. The writers might have eventually gotten the note on how pointless this was because under chancellor Sun-Tzu (No, really) Liao in 3052 the servitors were awarded more rights, their quasi slavery condition abolished and they were given better chances at gaining citizenship, boosting Sun-Tzu's popularity in the process. Just as planned. 

The Confederation is run by a Chancellor, who's supposed to be elected by the nobility but in reality is pretty much always the head of House Liao. This is rather unfortunate, since the Liaos have a noticeable tendency towards being batshit fucking insane ''even by Inner Sphere nobility standards''. They claim descent from Elias Liao, who was either a persecuted revolutionary philosopher (if you ask a Capellan) or a psychopathic nuclear terrorist (if you ask anyone else). The main family line births a homicidal maniac at least every other generation, e.g. Kali Liao, who became the leader of a cyborg death cult with a taste for mass nerve-gas attacks. At one point, they decided that having a regular military just wasn't cool enough for them and created the Warrior Houses, a bunch of weird pseudo-religious warrior cults that only answer to the Chancellor.

Since the Capellans have lost basically every war they've ever fought and live right next to the Federated Suns, they've become the designated "sneaky" faction, focusing on guerrilla warfare and covert operations. They go for stealth and electronic warfare the way the Davions go for autocannons, best exemplified by their iconic Raven electronic warfare 'Mech (which, depending on the model, actually looks like a bird; weird but cool). After the Clan Invasion and FedCom Civil War, they acquired a taste for the newly-developed Plasma weapons. Got the absolute shit beat out of them by the Federated Commonwealth during the Fourth Succession War, got revenge when the Commonwealth tore itself apart a few decades later.

====[[ComStar]]====
Imagine a cross between the medieval Catholic Church and Comcast, and you have ComStar. During the Star League Civil War, the network of Hyperpulse Generators that the Star League had built for faster-than-light communications was in ruins, and the one thing that the Great Houses could agree on was that ''somebody'' had to fix all their space phones right fucking now. They named Jerome Blake, the highest-ranking HPG network official still alive, as Minister of Communications, which, since they didn't name any other ministers, basically put him in charge of Terra. As the Star League collapsed, Blake bummed some soldiers off of Kerensky, got the Successor States to agree that the space phones were important and they should therefore respect ComStar's neutrality, and then seized complete control of Terra in a lightning-fast coup, revealing that that neutrality had some teeth.

After Blake died, ComStar quickly turned into a quasi-mystical and religious organization, whose stated purpose was to preserve human knowledge in the dark ages of the Succession Wars, a goal they attempted to fulfill by assassinating every scientist who wouldn't work for them and starting the Second Succession War practically the moment the first one ended. Things started to spiral out of control for them after the Helm Memory Core was leaked and suddenly everyone was able to figure out how Lostech worked again, and then things got even ''worse'' when the Clans showed up.

ComStar is also famous for introducing the ComStar Bill (C-bill) as a standard galactic currency.  Rather than being backed by material goods, each C-bill is backed by ComStar's faster than light message delivery service: One C-bill will guarantee one millisecond of data transmission, enough for a few pages of bare text or a small image, with larger transmissions costing more, and with additional fees for higher priority and the like.  The value of the various Great House currencies can be weighed against their worth in C-bills which allows for currency exchange on a galactic scale.  The C-bill is the primary way that mercenaries are paid and in turn pay for goods and services, and thus the most common currency encountered by players. Post Jihad, ComStar was neutered of its armed forces and subject to a hostile takeover by Clan Sea Fox (outside of the universe, at least one of the game developers had a hate boner against ComStar's OP status and gave their more powerful components the ax, courtesy of Blakist nukes).

====Minor Powers====
*'''[[Free Rasalhague Republic]]''': Space Norse/Vikings. They were a part of the Draconis Combine along the Lyran border, until the formation of the Federated Commonwealth meant that Kurita was about to have ''two'' borders for Hanse Davion to attack them from, so he granted them their independence as a buffer state. May have been awesome. If you're wondering why we write of them in the past tense refer to: ''Clan Invasion, Why Not Get in the Way of One'' (Third Publishing of Liao, COMSTAR ISBN 474-Alpha-467-Upsilon-345). They later join up with the Ghost Bears and become the Rasalhague Dominion. They are awesome because now we have Viking clanners. One of their aerospace pilots literally stopped the Clan invasion dead for an entire year because she banzai'd her fighter into a Clan warship and killed the ilKhan. 
*'''[[Word of Blake]]''': An ultra-reactionary splinter faction of ComStar that got butthurt after ComStar ditched all the pseudo-religious bullshit. Broke away and launched an all-out jihad (''yes, they actually used that word'') on literally everyone shortly after the Federated Commonwealth Civil War came to an end. Made liberal use of weapons of mass destruction and rendered several entire planets uninhabitable. Fond of genocide, re-education camps, unstable technology, and mass murder. As a result, they were eventually crushed as a result of pissing off the entire fucking universe, but not before undoing a lot of the technological progress that had been made after the [[Clan Invasion]] (apparently by magic, as not only was that knowledge now universally available, but so were copies of the Helm Memory Core...and destroying some factories doesn’t make technology go away). Basically used by the publishers to reset the average technology level of the game due to a lot of players feeling it was advancing too far and getting away from the quasi-feudal feel of earlier editions (forgetting that quasi-feudalism is a governing method, the technology level has nothing to do with it). Ironically enough, their 'Mechs were more streamlined and featured a lot more experimental technologies for people who would eventually blow the entire game setting back to the quasi-iron age. Officially, they were all supposedly killed after the Jihad for genocide. Recently hinted by a terminally ill Stone to still be around and responsible for the HPG network being taken out as a taunt against ilKhan Alaric before being killed off in bed.
*'''The [[Republic of the Sphere]]''': Established by an individual calling himself Devlin Stone, who mysteriously surfaced at some point during the Blakefag Jihad, and helped pull the galaxy out that colossal clusterfuck through a series of successful military campaigns. Upon the Jihad's defeat, Stone met with ComStar Precentor Martial Victor Ian Steiner-Davion and laid out a philosophy which Victor would privately describe as ''militant socialism keyed to altruism''; Officials and authorities would have their assets placed in a blind trust. Public service would be rewarded. Greed and corruption would be punished. All weapons would be placed under government control. [[Just As Planned|Surprisingly, it worked]], at least for a time, ushering in a new era of peace for the core worlds. However, after ruling as Exarch of the Republic for a while, Devlin Stone stepped down and shortly there after disappeared, vowing to [[Sigmar|return when he was needed most]]. It didn't take long before everything went to shit again and was plunged into chaos when the interstellar communication network was sabotaged. Was gangbanged by a combination of separatist factions, the Capellans, and Clan Jade Falcon before finally saying FUCK IT and retreating back to Terra. All while somehow using Word of Blake HPG disruption tech to prevent hyperspace jumps into their core territory. They also recently developed a taste for Tripod 'Mechs (which are the only modern 'Mech that can exceed Assault 'Mechs in terms of tonnage, firepower, and armor but at the cost of requiring an additional gunner and engineer onboard to shoot and monitor the machine's vitals) while also hybridizing Clan & IS technology (culminating with extremely powerful but unstable weapons). <strike>''You guys realize Stone is the [[Emperor]], right? Right?''</strike>  None of this makes sense, of course, as the HPG network is not only extremely well and fanatically protected by actual fanatics, but also is so large it can’t really be sabotaged.  Except by magically competent Deus ex Machina mooks, apparently.  Friendly clans could also build their own for the Republic’s use.  Except newly built HPGs also failed somehow.  Black Boxes became advanced enough that HPGs were nearly pointless, though, making the whole “Dark Age” thing really...dumb.  And if someone had the sense to build building-sized Black Boxes instead of briefcase-sized, the HPGs would have a perfect backup.  But common sense in BattleTech is [[heresy]] just like in any good universe.  Besides that, the eyes on anyone with power to prevent corruption would stop factions from selling out the Republic and the senators would not have been able to sponsor military officers into becoming Paladins because that is extremely corrupt and would not have been allowed or tolerated.  Even if such a plot succeeded, there would be no leverage for the senators to get those paladins to do what they wanted.  And the Capellans are target practice, sudden separatism makes no sense when they were fine until this point under numerous oppressive regimes, and Clan Jade Falcon by itself would have been crushed and a team up of clans would have sent the whole Inner Sphere into a clan-killing frenzy panic mode. Come the latest novels in 2021, and the Republic and it's founder were reduced to a caricature of fall of the III Reich (complete with a senile leader giving contradictory orders and throwing their best units at the worst faction so the best faction can pick up the pieces). While many of their leaders and fighters survived, it's an open question of whether they cooperate with the ilClan or revolt later down the line.
** '''Northwind Highlanders''': A band of Scottish mercenaries hailing from the planet Northwind.  Once upon a time they were a formal Royal Guard unit for House Cameron in the SLDF but they went free agent when the Star League fell apart, after which they mostly worked for House Liao.  They got a surprise happy blakesday party that destroyed their HPG and wiped out their aerofighters but otherwise they survived and joined the Republic in 3081. With the Fall of the Republic, they were forced to surrender with their leader loaned as a liaison from the ilClan to the Jade Falcons; which is notable due to both factions  historically and currently originating from, the Black Watch, elite SLDF units working as bodyguards for the First Lord of the Star League and nearly prevented the [[Amaris Civil War]].
* '''[[The Periphery]]''': The collection of non-successor states on the edges of the Inner Sphere. They were brought into the Star League by force and are still kinda sore about it, mostly because they nearly got blasted back to the Stone Age and never quite got their technology back up. The most important entities (outside of the Clans) are the Periphery powers bordering the Great Houses in the Inner Sphere while the rest is marked as the Deep Periphery and is as isolated from civilization as the Arctic Circle from the rest of civilization.
**'''[[Taurian Concordate]]''': Equivalent to the Space IRA/Ireland, they’re a Periphery nation bordering the Federated Suns and Cappellan Confederation. Has an axe to grind against the Federated Suns and claims they’re much more dedicated to freedom and liberty than the Davions. Think the United States right after 9/11, all of the good and the bad, and you have a good idea of the culture. Just replace paranoia about Islam with paranoid about the Federated Suns, including the fact that the overwhelming majority of who they're paranoid couldn't given any less of a shit about them. Also add the IRA, their fanatical hatred of the British, and war crime tendencies.
**'''Marian Hegemony''': A bandit kingdom bordering the Lyrans and Free Worlds League that decided to become the Roman Empire IN SPACE. They’re basically founded on by a noble consortium who struck gold with a vast deposit of germanium (a vital ingredient for KF Drives). Due to their practice of raiding for resources and slaves, all their neighbors (particularly the Lyrans and Free Worlds Leaguers) hate them. A shadier version of the [[Severan Dominate]] from 40k. 
**'''[[Rim Worlds Republic]]''': A former authoritarian and militaristic state formed during the Age of War. It was a poster child in the Star League due to its founders, House Amaris, proclaiming unconsummated loyalty to the League during the Reunification Wars. Unfortunately, House Amaris was as [[Angron|bloodthirsty]] as House Kurita and [[Lorgar|spiteful]] as House Liao. Due to perceived “betrayal” from the Star League not rescuing them fast enough from an anti-Star League mass revolt during the Reunification Wars, they held a secret grudge and then staged a bloody coup against House Cameron. After countless war crimes and purges as the SLDF ground through their defenses to Terra, they got eradicated in the [[Amaris Civil War]] with the bulk of their planets outright annexed by the Lyran Commonwealth. If the Word of Blake or the more extremist Clans like the Smoke Jaguars and Jade Falcons are the big bads in BattleTech, the Rim Worlds Republic is in a very close second or third place.
**'''[[Magistracy of Canopus]]''': Equivalent to Space Las Vegas, it’s a hedonistic matriarchy bordering the Free Worlds League. A nation of cybernetic catgirls, whose largest export is pornography. No, really. We're serious. Well they're not all cybernetic catgirls but they're there if you want them, and pornography and the tourist industry makes up a large chunk of their economy. Also Medical research and technology, most likely to treat all the STDs you get from your vacation to Space Vegas. Also known for having a significant religious conservatives population as they have an open-door refugee policy. 
**'''[[Outworlds Alliance]]''': Basically the Space Amish, they’re a backwater state near the Federated Suns and Draconis Combine. Was the Periphery-est of the Periphery states until Clan Snow Raven moved in and formed the '''Raven Alliance'''.
**'''Hanseatic League''': A mercantile alliance of traders descended from Lyran refugees fleeing economic declines during the Third Succession War, their nation is between the Clan Homeworlds and Lyran Space. They liked to pretend to be a neutral third party interested in trade of goods and information while also subjecting neighboring planets to debt trap diplomacy with armed merchant caravans. Also liked to play both sides against each other in any prolonged war among their neighbors to increase profits and soften them up for potential annexation (such as between Nueva Castille and the Umayyad Caliphate). Unfortunately, they were eventually conquered by Clan Goliath Scorpion (with help from their newfound Castilian and Umayyad citizens) and merged into their new Scorpion Empire some time in the Dark Age.
*'''Mercenary Review and Bonding Commission''': An independent group that certifies and provides force rankings for various [[Mercenaries (Battletech)|mercenary groups]]. At least three MechWarrior games are focused on the mercs as it allows writers more leeway and less chance to screw up the canon.  
**'''Kell Hounds''': A merc company headed by Morgan Kell. His son Phelan was captured by Clan Wolf when the Clan Invasion first began, and by the end was running the Clan until it split. Took in Phelan and the Exiled Wolves afterwards. Generally, are tough but cool guys all around. Like the Exiled Wolves, they got a massive "kill on sight" target painted on their back after the omnicidal Jade Falcon Khan got annoyed with their feisty resistance against her campaign into Lyran Territory. Once the Jade Falcons scrambled the bulk of their military forces to Terra, the Kell Hounds were able to retake their homeworld when the Jade Falcon occupation zone and Lyran northernmost territories balkanized from the power vacuum. On the other hand, their commander has a big grudge against the Steiners for leaving them out to dry.
**'''Grey Death Legion''': Mercenary group who were famous for finding and distributing the Helm Core, which allowed the Inner Sphere to regain technology formerly lost during the Succession Wars.  Generally an author's favorite in the books. Got destroyed during the Blake Jihad. And then got resurrected once the northern Lyran provinces balkanized.
**'''Wolf's Dragoons''': A bunch of Clan Wolf advance scouts disguised as a mercenary group. Came to the Inner Sphere with a ton of 'Mechs that the Clans considered outdated but hadn't been seen in the Successor States in centuries and were considered Lostech... Which should have tipped the Great Houses off that these guys might be bad juju.  Instead of providing intel to the Clans for their invasion, Wolf's Dragoons pulled a fast one and tried to prepare the Inner Sphere for war with the Clans. They are generally pretty awesome guys, even if part of that awesomeness is because they get a ton of attention in the fluff due to the writers' obsession with anything related to Clan Wolf. They got screwed pretty badly during the Blake Jihad when the nutjobs assaulted Outreach. By Dark Age they are slowly recovering with help from the Kell Hounds. Recent novellas have the Wolves convince them to join them on Terra once it's conquered to prevent the genocidal Jade Falcons from becoming the ilClan. Unfortunately, latest novels also made them become meatshields used by the Wolf Khan to expend the Turquoise Turkeys' ammo supplies while being reduced to a fraction of their strength. Naturally, in a repeat of their history against Kurita, they [[Book of Grudges|swore]] an oath to stand against the Wolves permanently.
