Chancellor of the Capellan Confederation
Barbara Liao had a baptism of fire upon assuming the Emerald Throne in 2760; four days after her ascension came news of the nuclear attack on a BattleMech factory on Demeter by the Chesterton Liberation Battalion with the Confederation and Federated Suns plunged into the so-called Border War. Immediately refuting Davion claims that the Maskirovka aided the CLB in destroying the factory, Barbara's attempts to bring the matter before the Star League High Council for adjudication were crippled by her insistence that the Capellan claims to Chesterton, Sonnia and Demeter also be reviewed at the same time. With the other Great Houses long considering the claims comical, refusing to even consider such Capellan motions since 2582, the conflict would rage on until it was overshadowed when First Lord Richard Cameron reached his majority, with the Chancellor and First Prince agreeing to halt the fighting. 
Though more idealistic than her more pragmatic father, Barbara would continue the post-Council Edict of 2650 repeal build-up of the Capellan Confederation Armed Forces, using quality training and Terran Hegemony aid to combat the CCAF's smaller size in comparison to its neighbors.
After the Coup she refused to directly aid General Aleksandr Kerensky in his moves against Stefan Amaris, citing a legal pretext that it was an "internal Terran matter", the same reason given for the SLDF's non-intervention in the Marik Civil War. While this was not popular with her people and the Chancellor personally felt sympathy for Kerensky's cause, Barbara steadfastly believed the Confederation's involvement in the dispute would weaken it in the face of Free Worlds and Federated Suns militarism. Political unrest resulted and eventually the Chancellor gave her permission for the SLDF to use Confederation worlds, though she stopped short of offering comfort and support to the campaign.
As Operation CHIEFTAIN drew to a close with the SLDF advancing closer and closer to Terra, Barbara Liao authorized a significant increase in aid to the liberated Hegemony worlds closest to the Confederation, relieving the exhausted SLDF of their relief efforts but effectively placing these worlds under House Liao control. Though a less than ideal arrangement, a desperate General Kerensky would agree to such de-facto absorptions in order to free up as many as his troops as possible and in return for military supplies from the Chancellor. 
After the conclusion of Operation LIBERATION, Barbara Liao would meet with the other Council Lords in Unity City for the first time in sixteen years on October 10th 2781. Unfortunately self-interest and squabbling ruled the day and the Council Lords would agree on only two things, the selection of Jerome Blake to rebuild the shattered Hyperpulse Generator network and stripping from General Kerensky the role of Protector of the Realm. Though she would vote with the others, Kerensky's silent response to the humiliation of the removal would leave Barbara Liao heartbroken. As the full horrors of the First Succession War took hold, she would later openly regret her role in Kerensky's removal, likening it to a crime that doomed the entire Inner Sphere.
First Succession War
When the Star League collapsed, Barbara’s foresight became clear and the expanded CCAF made significant gains against the Federated Suns in the First Succession War, most notably capturing the Suns' so-called Terran Corridor. With House Davion preoccupied by a mass Draconis Combine invasion, the Confederation would also claim a considerable volume of former Hegemony worlds facing Liao and Davion space, easily taking Carver V, Keid, Terra Firma Bryant, Epsilon Indi, Epsilon Eridani, Fletcher and Hsien.  
The Confederation was less fortunate in its clashes with the Free Worlds League, as House Marik launched a successful offensive that took numerous border worlds. Desperate to push the League back, Barbara Liao sent a massive Capellan flotilla to stage a deep strike against the League world of New Delos. In preparing her troops for the battle, Barbara would issue one of the most infamous orders of the First Succession War, indicating the Ares Conventions were suspended and authorizing mass civilian casualties in an attempt to teach the Free Worlds League the price of striking the Confederation and bullying them into retreat. Using recently captured Marik codebooks, Strike Force Devlin took the vastly outnumbered Marik defenders by complete surprise before engaging in three days of wanton slaughter, withdrawing from New Delos after killing over 20,000 civilians.  
Unfortunately Barbara's "Devlin Solution" had the complete opposite effect, with the enraged Free Worlds League Military eager to avenge the dead of New Delos, retaliating with the fire-bombing of Outreach, Ingersoll and New Canton in 2789. Unbowed, in February 2790 Barbara selected Calloway VI as the next target, choosing to accompany Strike Force Devlin over the strenuous objections of her civil and military aides. This time lacking the advantage of codebooks and with the Marik forces prepared for any sudden moves across the border, the Capellan fleet was instantly set upon after arriving in the Calloway system. While able to reach the planet, the Capellans faced heavy opposition, the offensive greatly hampered by the need to keep the Chancellor safe from harm. After ten fruitless days she finally ordered Strike Team Devlin to withdraw, running directly into the teeth of a Marik relief force responding to Calloway's calls for help. Sacrificing the cream of the Capellan navy, Barbara would barely escape with her life, with both her sons killed during the debacle. 
The final years of Barbara's reign would see the Confederation suffer defeat after defeat, with the weakened Capellan navy unable to maintain the blockades of Marik-held Corey and Wazan, and the Marik Militia supported by Smithson's Chinese Bandits successively occupying El Giza, Mosiro, Vanra and Carbonis. Further, the Draconis Combine would increasingly challenge her efforts to claim former Terran Hegemony worlds, leading to costly battles over the planets of Rio and Ronel.
Death and Legacy
Barbara Liao would die from a rare blood disorder in 2795. While her granddaughter Ilsa was the next surviving Liao in the line of succession, she was at the time far too young to ascend to the Celestial Throne. In response the Capellan Prefectorate chose Sandol Quinn, Prefect of the Tikonov Commonality, to act as regent until the 12 year old Ilsa reached her majority.  
Children and Succession
Barbara Liao had two sons Baltazar Liao and Barnabus Liao, both of whom died during the First Succession War. The next Chancellor in the bloodline would be Ilsa Liao a daughter of one of her sons.
