The Battletech universe is a diverse place, spanning more than a millenium of history and several thousand light years of space. From the nation states of the 20th century up to the Republic of the Sphere of the 32nd century, Battletech spans myriads of places and trillions of people. Interstellar, succession and civil wars, fragmentation and infighting gave birth to countless factions, of which most are noted below.

Regions of Space

Inner Sphere

Main article: Inner Sphere

The Inner Sphere is the heart of the Battletech Universe. Centered around Terra, it stretches across roughly 500 light years in all directions. The most consolidated of all interstellar regions, the Inner Sphere is dominated by five Great Houses.[1]

Main article: Periphery

The Periphery refers to the region of space immediatly surrounding the Inner Sphere. The border between Periphery and Inner Sphere is generally 450 - 550 light years away from Terra. The Periphery is surrounded by the Deep Periphery, though the borders for this region of space are more nebulous. The Periphery is littered with small colonies and a handful of interstellar nations.

Deep Periphery

Main article: Deep Periphery

Deep Periphery refers to the depths of unexplored space and/or human colonized space located beyond the (known) coherent human sphere of influence, namely the Inner Sphere and the adjacent Periphery realms. Due to the vague nature of the term "Deep Periphery", there is no clearly defined beginning nor are there any boundaries. [2]

Clan Homeworlds

Main article: The Clans

The Clans were originally the self-exiled remnants of the Star League Defense Forces. Travelling 2000 light years corewards, they colonised several worlds in the Kerensky cluster. The exiles evolved into a warrior-based civilization that would sweep through the Inner Sphere like a whirlwind 250 years later. [3] The current factions in the Clan Homeworld are unknown.

Historical Factions

Early Spaceflight

Main article: Early Spaceflight

Between the mid-20th and the early 22nd century, Terra began a long process of political unification, first into the Western, then the Terran Alliance. At the same time, developement of a practical Fusion Engine allowed for the first off-world colonies, on Luna, Mars, and Venus. [4]

First Exodus

Main article: First Exodus

After the success of the Deimos Project, the era of the First Exodus was one of rapid expansion and colonisation - both sanctioned settlers and dissidents fleeing the increasingly repressive Terran Alliance had established 600 known colonies by 2235. The Outer Reaches Rebellion ended the First Exodus, as the Terran Alliance completely withdrew from its colonies. [5]

Second Exodus

Main article: Exodus (2242)

Due to the power vacuum of the Alliance's withdrawal, chaos and warfare broke out. Many colony worlds were no longer sustainable or subject to prolonged conflicts, their inhabitants again took to the stars, spreading even beyond the settlement boundary of the First Exodus. Meanwhile, the first true interstellar states formed, fought and absorbed each other until the Inner Sphere consolidated into an armed standoff between the six Great Houses.[6]

Age of War

Main article: Age of War

The Age of War began in 2398, when the Houses Liao and Marik fought over Andurien. Initial savagery was eventually followed by the ratification of the Ares Convention, a set of guidelines which made war much less brutal, but also a near constant occurrence. Thanks to the Terran Hegemony's Strategy of Aggressive Peacemaking, the Age of War ended with the signation of the Star League treaties by the six Great Houses.[7]

Star League Era

Main article: Star League Era

Formally unifying the Member States of the Inner Sphere in 2751 and officially subjugating the Territorial States of the Periphery in 2597, the Star League Era was one of overt peace and hidden wars. Later called a Golden Age by many, the Star League allowed for peace, prosperty, and significant technology progress. Weakened by a string of bad rulers, hidden wars, and unrest in the Territorial States, the Star League eventually collapsed after the Amaris Civil War.[8]

Golden Century

Main article: Golden Century

After the fall of the Star League, Operation Exodus of the Star League Defense Forces led them into the Kerensky cluster, where they settled down. After falling into civil war and a second Operation Exodus, the remaining loyalist SLDF forces reorganised themselves into the Clans and retook the war-stricken worlds. The Golden Century was the following period filled with unprecedented growth, technological progress, and a maturation of each Clan's individual self identity. [3]

Succession Wars

After the collapse of the Star League and the exodus of the SLDF, the five remaining Great Houses - after dividing the remaining Terran Hegemony among each other - began a series of brutal wars to claim the position of First Lord. The first two Succession Wars, apocalyptic conflicts encompassing the entire Inner Sphere, brought technological knowledge down to levels last seen on pre-spaceflight Terra, and only the establishment of ComStar on independant Terra prevented a total collapse of interstellar communication. The Third Succession War became an endless downward grind, led by neo-feudalistic Mechwarrior families and covertly helped along by the increasingly corrupt ComStar. It was only the Fourth Succession War that brought a fragile peace and a new status quo to the Inner Sphere - the victorious powers of the Federated Commonwealth (at the time merely an alliance between Federated Suns and Lyran Commonwealth) against the Concord of Kapteyn of Free Worlds League, Capellan Confederation, and Draconis Combine.[9]

Clan Invasion

Main article: Clan Invasion

After almost 3 centuries in exile, the Clans returned to the Inner Sphere in a coordinated drive towards Terra until losing a trial on the planet Tukayyid, agreeing to a 15 year long truce. With the Clan threat temporarily eliminated, the Great Houses went back to fighting each other - the barely established Federated Commonwealth broke apart again, the Word of Blake led an Exodus out of ComStar, and an entire region of space descended into anarchy. When the hastily established Second Star League managed to destroy Clan Smoke Jaguar during the Refusal War, the Clan invasion was finally over, but the problems in the Inner Sphere were only beginning to escalate.[10]

Civil War Era

Main article: FedCom Civil War

Nominally a civil war between the two halves of the sundered Federated Commonwealth, the Civil War quickly degenerated into a conflict involving all major Inner Sphere powers, an uncounted number of mercenary units, and several of the relocated Clans. At the end of the conflict, the Federated Commonwealth was gone forever, with the Federated Suns and the Lyran Commonwealth being recreated by their new rulers.[11]

Main article: Jihad

The Word of Blake Jihad began as an impulsive reaction by the Word of Blake after the fall of the Second Star League in 3067. It eventually escalated into a series of conflicts between most major Inner Sphere and Periphery factions, leaving several realms (last among them the Word of Blake itself) utterly destroyed. United in a fragile coalition, the Anti-WoB forces eventually forced the Word back unto Terra itself, which was finally reclaimed in 3078. [12]

Main article: Mercenary Units

Modern mercenaries have their root in the chaos of the Second Exodus, when they were commonly used in the hundreds of border conflicts between the emerging statelets. In use during the hidden wars of the Star League members, mercenary units began to multiply in numbers and power since the beginning of the Succession Wars. Even in later eras, mercenaries retain their prominent role in military conflicts.[13]
