BattleTech Great Houses Guide

The five Great Houses of BattleTech are the ruling families of the Inner Sphere’s Successor States: House Davion (Federated Suns), House Kurita (Draconis Combine), House Liao (Capellan Confederation), House Marik (Free Worlds League), and House Steiner (Lyran Commonwealth). Each house controls hundreds of worlds, fields massive armies of BattleMechs, and has spent centuries fighting the others for supremacy. If you want to understand BattleTech lore, you start here.

I have written novels set in the territory of several of these houses. The political dynamics between the Great Houses shape every conflict in the BattleTech universe, from the Succession Wars through the Clan Invasion and into the ilClan era. This guide covers each house’s identity, its strengths, its signature fiction, and why it matters to the setting as a whole.

What Are the Great Houses in BattleTech?

The Great Houses are the five ruling dynasties that have controlled the Inner Sphere since the fall of the Star League in 2781. Each house governs a Successor State, a nation of hundreds of colonized worlds connected by JumpShip travel and HPG communication. The name “Successor States” comes from their claim to be successors of the Star League, the interstellar government that once united humanity under House Cameron.

When House Cameron was destroyed during the Amaris Civil War and General Aleksandr Kerensky led the bulk of the Star League Defense Force into exile, the five remaining Great Houses turned on each other. The wars that followed (the Succession Wars) lasted for nearly three centuries, devastating entire worlds and causing widespread technological regression. By the time the Clans returned to the Inner Sphere in 3050, the Great Houses had been fighting each other for so long that the conflict defined their national identities.

Each house draws on distinct cultural influences, governs through a different political structure, and fields a military with its own doctrinal preferences. The table below summarizes the five houses and their Successor States.

Great House	Successor State	Capital World	Cultural Influence	Ruling Title
House Davion	Federated Suns	New Avalon	Western and Central European	First Prince
House Kurita	Draconis Combine	Luthien	Japanese feudal	Coordinator
House Liao	Capellan Confederation	Sian	Han Chinese	Chancellor
House Marik	Free Worlds League	Atreus	Multicultural (Mediterranean, North American)	Captain-General
House Steiner	Lyran Commonwealth	Tharkad	Germanic and Northern European	Archon

House Davion: The Federated Suns

House Davion rules the Federated Suns, the largest of the Successor States by volume of territory. Founded in 2317 by Lucien Davion on New Avalon, the Federated Suns positions itself as the most open and democratic of the Great Houses. Its citizens enjoy broader freedoms than most Inner Sphere inhabitants, and the state invests heavily in military research through institutions like the New Avalon Institute of Science (NAIS).

The Davion military doctrine favors combined arms and aggressive maneuver warfare. Their Armed Forces of the Federated Suns (AFFS) field some of the best-trained conventional and ‘Mech forces in the Inner Sphere. Signature units include the Davion Brigade of Guards and the elite Crucis Lancers.

House Davion’s defining political relationship is with House Steiner. The marriage of Hanse Davion and Melissa Steiner in 3028 created the Federated Commonwealth, briefly uniting the two largest Successor States into a single superpower. That alliance collapsed during the FedCom Civil War (3062 to 3067), splitting the two houses apart with lasting bitterness on both sides.

In fiction, House Davion dominates the Succession Wars and Civil War eras. Michael A. Stackpole’s Warrior trilogy (En Garde, Riposte, Coupe) is the definitive Davion-Steiner political novel sequence. Robert N. Charrette’s Heir to the Dragon provides the Kurita perspective on the Davion rivalry, and Loren L. Coleman’s Endgame closes the FedCom Civil War arc.

House Kurita: The Draconis Combine

House Kurita governs the Draconis Combine, the most militaristic of the Successor States. Founded in 2319 by Shiro Kurita, the Combine is structured around the Coordinator, an autocratic ruler whose authority is total. The state’s Japanese feudal culture emphasizes personal honor, rigid hierarchy, and the warrior caste, codified in the Dictum Honorium.

The Draconis Combine Mustered Soldiery (DCMS) is built on discipline and obedience. Units like the Sword of Light regiments are among the most feared in the Inner Sphere. The Combine also maintains the ISF (Internal Security Force), one of the most effective intelligence agencies in BattleTech lore, and the Order of Five Pillars as a secondary security apparatus.

House Kurita’s traditional enemy is House Davion. The Davion-Kurita border has been the most active front in the Succession Wars, producing some of the most iconic battles in the setting. The Clan Invasion changed the calculus: Luthien itself was threatened in 3052, and the Combine was forced into temporary alliance with its rivals to survive.

Robert N. Charrette’s Wolves on the Border is the essential Kurita novel, following the Wolf’s Dragoons mercenary unit through Kurita politics and honor culture.

Heir to the Dragon continues the Kurita perspective with the rise of Theodore Kurita. For the Clan Invasion era, the defense of Luthien appears in Michael A. Stackpole’s Blood of Kerensky trilogy.

House Liao: The Capellan Confederation

House Liao rules the Capellan Confederation, historically the smallest and most embattled of the Successor States. Founded on Capella in 2366 as a defensive alliance against Davion expansion, the Confederation has spent centuries fighting to survive against larger neighbors. The state’s Han Chinese cultural foundation shapes its political structure, centered on the Chancellor’s authority from the Celestial Throne on Sian.

The Capellan military has always been smaller than its rivals, which has pushed the Confederation toward asymmetric warfare: intelligence operations, guerrilla tactics, espionage, and the warrior-monk traditions of the Warrior Houses. The Capellan Confederation Armed Forces (CCAF) compensate for size with ideological commitment and unconventional strategy.

The Fourth Succession War (3028 to 3030) was catastrophic for House Liao. Hanse Davion’s coordinated offensive stripped the Confederation of nearly half its territory. The Confederation spent decades recovering, and Chancellor Sun-Tzu Liao’s diplomatic maneuvering during the Clan Invasion era began a long rebuilding process that continued through the Jihad and into the ilClan era.

I wrote Blood Will Tell specifically to get inside Capellan politics at the highest level. The novel follows Danai Liao-Centrella as she tries to end the war with House Davion while serving Chancellor Daoshen Liao during the ilClan era. Readers who want to see the Confederation from the inside, with all its internal contradictions, will find it there. For earlier eras, the Warrior Houses and the Fourth Succession War’s impact on House Liao are covered extensively in Stackpole’s Warrior trilogy.

House Marik: The Free Worlds League

House Marik governs the Free Worlds League, the oldest of the Successor States, founded in 2271. The League is unique among the Great Houses in having a parliamentary structure: the Captain-General leads the state, but Parliament on Atreus holds real legislative power. The League’s multicultural, decentralized character makes it politically fragile. Provincial governors can raise their own armies, and civil wars have been a recurring feature of League history.

The Free Worlds League Military (FWLM) reflects this decentralization. Combined arms doctrine is standard, and the League fields strong conventional forces alongside its BattleMech regiments. The Knights of the Inner Sphere, an elite order, represents the League’s connection to Star League traditions.

The Free Worlds League was untouched by the Clan Invasion, which allowed it to become the Inner Sphere’s industrial base during the 3050s. That advantage came with a price: the Word of Blake, a splinter faction of ComStar, embedded itself within the League. When the Jihad erupted in 3067, the League was at the center of the devastation, and the state eventually fragmented entirely.

House Marik is underrepresented in BattleTech fiction compared to Davion, Steiner, and Kurita. Christopher Kubasik’s Ideal War focuses on the Knights of the Inner Sphere. Randall N. Bills’ Pandora’s Gambit covers the Dark Age power struggle for the Captain-Generalship. For the League’s collapse and reconstruction, the novels become more ensemble-focused.

House Steiner: The Lyran Commonwealth

House Steiner rules the Lyran Commonwealth, the wealthiest of the Successor States. The Commonwealth’s Germanic cultural roots and mercantile tradition have produced the strongest economy in the Inner Sphere, and its industrial output exceeds any rival’s. The Archon governs from Tharkad, and the state’s political culture blends aristocratic privilege with commercial pragmatism.

The Lyran Commonwealth Armed Forces (LCAF) have a reputation for fielding heavy and assault ‘Mechs in numbers that other houses cannot match. The “Steiner Scout Lance” joke (four Atlas assault ‘Mechs on a reconnaissance mission) exists because it contains a grain of truth: Lyran doctrine historically favored overwhelming force over tactical finesse. The flip side of that wealth is the “social general” problem, where aristocratic connections mattered more than battlefield competence in officer promotion.

The Steiner-Davion alliance and its collapse define much of the setting’s political arc from the late Succession Wars onward. The Federated Commonwealth era (3028 to 3057) reshaped the Inner Sphere’s balance of power, and the FedCom Civil War that followed produced some of the most dramatic fiction in the line.

The Warrior trilogy is as much a Steiner story as a Davion one: Katrina Steiner, Melissa Steiner, and the politics of Tharkad are central to the plot. For the Civil War era, Loren L. Coleman’s sequence (Binding Force, Flashpoint, Endgame) and Blaine Lee Pardoe’s Archer Christifori trilogy (Measure of a Hero, Call of Duty, Operation Audacity) cover the Steiner-Davion split from multiple angles.

What Is the Difference Between a Clan and a House?

The Great Houses are hereditary ruling families of the Inner Sphere’s Successor States, nations that trace their origins to the earliest human colonies. The Clans, by contrast, descended from the Star League Defense Force soldiers who followed General Kerensky into exile after the fall of the Star League in 2781. The Clans developed an entirely separate civilization in the deep Periphery, organized around warrior bloodlines, genetic breeding programs, and ritualized combat (Trials).

The two groups collided in 3050 when the Clans invaded the Inner Sphere. Their superior technology (OmniMechs, Elemental battle armor, advanced weapons) initially overwhelmed the Great Houses, but the Inner Sphere’s larger population base, industrial capacity, and willingness to use tactics the Clans considered dishonorable eventually turned the tide. The Battle of Tukayyid in 3052 imposed a fifteen-year truce, and the destruction of Clan Smoke Jaguar in 3059 to 3060 broke the invasion’s momentum.

The BattleTech Clans Explained reference covers all twenty Clans in detail. The BattleTech Clan Invasion Guide covers the invasion’s timeline, key battles, and recommended reading.

Novels by Jason Schmetzer Set in Great Houses Territory

Blood Will Tell (2021) is set in the Capellan Confederation during the ilClan era. The novel follows Danai Liao-Centrella, a Solaris gladiator and military commander, as she contends with Chancellor Daoshen Liao’s court while preparing the Confederation for the Republic of the Sphere’s return. Readers on Amazon and Goodreads have described it as one of the strongest Capellan novels in the line. If you want to understand House Liao from the inside, with the political maneuvering and internal tensions that define the Confederation, this is where I would point you.

Blood Will Tell is available in paperback, ebook, and audiobook.

Mercenary’s Honor (2021) follows a mercenary unit operating across Great Houses borders, dealing with the political fallout of conflicting loyalties to different Successor States. The mercenary perspective is valuable for understanding how the Great Houses look from outside their own propaganda.

Mercenary’s Honor is available in paperback, ebook, and audiobook.
