The Liang dynasty was one of the Southern Dynasties, established by Xiao Yan, also known as Emperor Wu of the Liang (r. 502-549). He was a dynamic ruler whose reign was marked by unprecedented cultural and military advancements; the capital, Jiankang (modern Nanjing), became the world's most populous city, thriving as a cultural and commercial hub.
However, in 548, Hou Jing, a defected general of the Northern Dynasties, rebelled. The next year, he captured Jiankang after a brutal five-month siege and Emperor Wu passed away shortly after that. The Hou Jing rebellion left the Southern region absolutely devastated; in 549, the once bustling Jiankang was reduced to ruins, and a significant number of both elite and commoners lost their lives in the siege and subsequent civil conflicts that ravaged the South, marking the last time any Southern Dynasty would come to dominate Chinese politics, for, from this point onwards, the Northern Dynasties would be the ones to call the shots in East Asia. The short-lived Chen and Sui succeeded the Liang before the stage was set for the illustrious Tang. Hou Jing's actions therefore had a causal and yet notable impact on these historical developments.
As for Hou Jing himself and his endeavors, they were ultimately unsuccessful: Hou Jing at first managed to garner an unexpected level of backing, not just from the urban lower classes, but also from certain heirs of influential capital families. They likely perceived him as a potentially valuable ally in the widely acknowledged fierce contest to replace the weakened Xiao Yan, emperor of the Liang, yet none really expected him to make a good bid for that position. The imperial princes thus viewed each other as their primary adversaries, rather than considering Hou Jing a significant threat. Consequently, they plunged into a bitter and multifaceted civil war, unparalleled in the history of the Southern Dynasties, while Hou Jing enjoyed a period of relative dominance, maintaining control over Jiankang for nearly three years. During this period, he looted the city to amass funds for rewarding his supporters, entered into marriage with Xiao Gang's daughter, and arranged unions between his top generals and women of the imperial aristocracy. Ultimately, he orchestrated Xiao Gang's abdication (followed by execution) to ascend to the throne himself as emperor Wanjing of a new Han state. In the summer of 551, Xiao Yi, one of the brothers of the executed emperor Gang, reversed the fortunes of Hou Jing's campaign, and he and his forces began to advance downstream towards Jiankang. Xiao Yi's chief commander, Wang Sengbian, joined forces with another significant army commanded by Chen Baxian, which had traveled north via Jiangxi after a series of civil wars in Lingnan. By late spring of 552, the two armies were assaulting the capital, leading to Hou Jing's escape and eventual assassination. Hou Jing's downfall paved the path for Xiao Yi to seize the throne for himself, a feat he accomplished by the year's end.
So, what if Hou Jing's rebellion succeeded early on to prevent all the massive damage and decimations of the Southern potentates? Preventing the destruction of much of Jiankang and its ruling elite and the de facto independence of all of the provincial garrisons would prevent the Northern Dynasties from meddling in the South to the degree it did IOTL, and at least allow for Hou Jing and his potential successors to form an adequate response to the Northern threats. Furthermore, assuming that Hou Jing manages to regain control over the local provinces, such developments might more permanently establish a North-South division of the Sinic region, if not culturally, then at least politically, as a successful Hou Jing would merely be yet another extension of the ongoing period rather than commencing the beginning of the end of this warlord era, a task the Chen would utterly fail. Would Hou Jing even succeed in creating a stable dynastic Han state? What would the consequences be for the Northern Dynasties or the steppe peoples? What unsuspected butterflies might emerge from such a development? I'm all ears for any such speculations!
