House Calderon was the dynastic ruling house of Taurus, the Taurian Homeworlds, and the Taurian Concordat. From its founding in 2335 to 3060, the Protectors of the Realm of the Taurian Concordat were all Calderons (with the exception of a single regent). Despite its continued reign, the Calderon line was fair, egalitarian, and pragmatic in their decisions.[citation needed] However, frontier existence and surviving the depredations of the Inner Sphere also made the Calderons overly xenophobic.


Morals are one thing. Survival is everything.[1]

-Samantha Calderon, October, 2252, reported in Modern Explorers[2]


House Calderon are the decendants of Samantha Calderon, the wealthy heiress-businesswoman turned pioneer. Samantha decided to leave the Inner Sphere as a result of the brutality inherent in the nascent Inner Sphere, especially during (and in the wake of) the Outer Reaches Rebellion.

Samantha married a wealthy businessman who ran a Terraforming concern out of Vega, and started a family on Aix-la-Chapelle. When Samantha's husband and two daughters were murdered by a Terran Alliance firing squad during the Outer Reaches Rebellion in 2236, Samantha suddenly found herself in possession of a sizable fortune. However, assets dwindled due to the efforts of Marik pirates. Rather than allow her wealth to erode, Samantha decided to seek the safety of the Periphery. Samantha's call for pioneers to form a settlement expedition was answered by thousands of disaffected Spheroids. With a fleet of 25 Jumpships, the Calderon expedition left Aix-la-Chapelle in 2250, traveling rimward around the Terran Alliance, then rimward.

22 months after departing New Syrtis, the fleet arrived in the Hyades Cluster, a system of 8, mutually-orbiting stars, surrounded by no fewer than 37 planetoids, several habitable by humans. However, the path from the jump point to the system required navigating a giant asteroid field occluded by Flannagan's Nebulea. Though the fleet lost 8% of its vessels, including one which bore Samantha's second husband, Victor Taurens, Samantha decided that the Hyades asteroid field provided a fantastic natural barrier to invasion and piracy. The expedition founded the first of the Taurian worlds, Taurus, on 23 January 2253, and quickly commenced colonization efforts on the other habitable worlds within the system.

Samantha died in a freak accident in 2268, leaving her son Timothy as her sole heir. Despising the hated, brutal, but democratic Terran Alliance, Timothy and the Taurian people agreed that the Protectorship would remain a hereditary Calderon title, further distinguishing the Taurians from the heart of the Inner Sphere. It was Timothy who established egalitarian Taurian social policy - food for work.



Members of the Calderon dynasty willingly led the Taurian people, despite the hardship of life away from the Inner Sphere. In order to get by, the leaders of House Calderon generally displayed the following personality traits:

  • pragmatic
  • egalitarian
  • resolute
  • ernest
  • idealistic

However, as the Taurian people originated from Inner Sphere refugees, wide-spread fear of outsiders also pervaded society, only to be reinforced by (virtually all) later dealings with Inner Sphere powers. Therefore, the Calderons (and the Taurian Concordat in general) also were:

  • paranoid
  • xenophobic

Less Common[edit]

In times of conflict with the Inner Sphere, the leaders of House Calderon were forced into some grave circumstances. Their actions given those circumstances allowed other traits to come to the surface:

  • audacity
  • innovation
  • equanimity


Ultimately, House Calderon's actions always seemed intended to promote the greater good of the Taurian people. Whether the consequences of their actions actually were beneficial to the Taurian Concordat is debatable, on a grand or microcosmic scale.

On a grander scale, two glaring examples present themselves. The Calderon expedition chose to settle within the Hyades cluster in part because of the natural defense the Hyades asteroid field provided. When war came to the Concord, though, hiding within the asteroid field allowed the far-flung colonies of the Concord to be depredated. Further, while the military stance of the Concord may have indeed been necessary - especially given the early history of the Taurians with their two neighbors, the Federated Suns and the Capellan Confederation, but this policy drew the unwanted attentions of the nascent Star League. Through the Reunification War, the Taurian Concordat was transformed from a viable, powerful Periphery entity into a ravaged shell.

On a much smaller scale, the case of Amalthia Kincaid is another great example. General Kincaid was successfully conquering the Taurian Concordat during the Reunification War, with a minimum of casualties on either side. The Concordat, possessing a weapon which could only kill a seriously-ill person, assassinated the sickly Kincaid. The void left by Kincaid's death allowed General Amos Forlough to conduct war against the Concordat. General Forlough wasted did not waste any effort in destroying (literally burning) world upon world and slaughtering millions of innocents.

Ability to Wage War[edit]

The Taurian Concordat was essentially established as a mutual protection pact, fearing that larger Inner Sphere neighbors would depredate a defenseless Periphery state. Though there is a much greater degree of freedom within the Concord relative to Inner Sphere powers, the Concord has always put an emphasis on and taken great pride in being able to protect itself. All Taurian citizens must enlist in military service for at least 4 years, though most will never see a battlefield. Frontline soldiers are also extremely capable fighters, given their extensive training and schooling. The only exception to this lies within the Concord's Aerospace assets, a flaw the Concord tried to rectify in the 3040s with the help of the Outworlds Alliance.

The military-industrial complex of the Concord is also capable of maintaining a healthy fighting force. Indeed, before the Reunification War, the Taurians were the second Periphery nation to field BattleMechs (after the Rim Worlds Republic, who assisted the Lyran's efforts to steal the original schematics), and boasted the largest Warship fleet beyond the Inner Sphere. Lacking self-sufficiency and and having lost a majority of its territory after the Reunification War, including its entire capacity to construct and maintain Warships, the Taurians still maintained enough production to field a sizeable BattleMech army, supplemented with combat vehicles and infantry.

With advances in lostech, especially after 3060, the pace of technological development within the Concord began outstripping the abilities of technicians to keep pace. Combined with the succession crisis caused by the death of Protector Jeffrey Calderon, and the thinly spread resources (gambling on colonization), the Taurian Concordat of the latter half of the 31st century has become a nation close to collapse. Though traditionally the Concord was one of the most stable Periphery realms with a very capable army, the Concordat has become a mere spector of its former glory.

  • One probably would not conceive a child during interstellar travel, meaning any child by a third husband would have probably been born in 2254 or later.
  • Timothy would have been at most 14 years old when he took the Protectorship.
  • Firing squads do not generally shoot infants (may Terran Alliance firing squads do, though...). It is unlikely to have daughters old enough to be shot by a firing squad if you are not already 20 (reasonably, a young Samantha might have been 25 years old). This means that Samantha would be at least 38 (probably closer to 45) if she gave birth to Timothy by a third husband.

* - though not explicitly stated, it may be implied that the Calderon line did not experience a succession crisis until the death of Marantha Calderon[3]

- no information is about the parents of Nicoletta. For that matter, it is likewise unclear if the line of succession remained unbroken between Nicoletta Calderon and Zarantha Calderon, and how many generations come in between.
