YeLu LongXu

YeLu LongXu, known in Liao history as the Holy Emperor, set in motion the succession history that later divided his descendants. Before his death, he designated his eldest son ZongZhen as heir rather than his second son ZhongYuan, whose military talent made him a formidable alternative; the settlement held at first, but the throne eventually passed to ZongZhen’s son HongJi, leaving ZhongYuan’s claim and influence at the heart of a later rebellion.

Place in the Succession

The Holy Emperor had two sons with sharply different reputations. ZongZhen was kind and generous, while ZhongYuan was valiant and skilled in military strategy. As the Holy Emperor approached death, he named ZongZhen to succeed him. That choice established the direct line of succession, but it did not erase the political force of ZhongYuan’s abilities or the possibility that others might prefer him as ruler.

The succession decision became a family crisis when the Empress favored her second son and plotted to make ZhongYuan emperor. The account emphasizes the power held by an empress dowager in Liao tradition: ZongZhen could not fully consolidate his authority, and his life was in danger. Yet ZongZhen told his brother of their mother’s scheme, and the plan was thwarted. His brother’s support preserved the succession chosen by the Holy Emperor, while ZongZhen’s gratitude strengthened ZhongYuan’s standing rather than diminishing it.

A Compromise That Reshaped the Dynasty

ZongZhen, later remembered as the Prosperous Emperor, rewarded ZhongYuan by granting him the rank of royal emperor brother and placing him next in line to succeed. ZhongYuan, in turn, had been able to take the throne with the Dowager’s support but gave it up and backed his elder brother; he also kept quiet about the attempted scheme. The brothers’ settlement combined deference to the Holy Emperor’s choice with an exceptional elevation of the younger son.

When ZongZhen died, however, the throne passed not to ZhongYuan but to ZongZhen’s son HongJi. HongJi responded to the unresolved question of precedence by naming ZhongYuan royal emperor uncle and again making him heir presumptive. He also made his uncle commander-in-chief of the entire army, exempted him from kneeling at court, and bestowed gold, scriptures, a mortar board, and a two-colour robe. The honors acknowledged ZhongYuan’s sacrifice and rank, but the concentration of succession status and military authority in one branch of the family also left the dynasty vulnerable when the next generation turned against HongJi.

The Rebellion’s Inherited Fault Line

The later crisis exposed the limits of the arrangement. HongJi had left the capital to hunt and entrusted military affairs to his uncle, while ZhongYuan’s son NieLuGu held the office of Lord of the Southern Chancellery and controlled its military administration. When rebellion broke out, NieLuGu proclaimed his father emperor and issued an edict describing HongJi as a false ruler who had usurped the throne. The claim drew its force from the earlier succession history: ZhongYuan had once been positioned to inherit, had yielded to his brother, and had again been designated successor under HongJi.

HongJi feared that the edict would weaken loyalty among the army and people, especially because ZhongYuan was commander-in-chief and could mobilize an immense force. The rebellion therefore grew from more than a son’s revolt against his cousin: it reopened the succession settlement whose origins lay in the Holy Emperor’s choice between ZongZhen and ZhongYuan. The narrative makes YeLu LongXu significant through this long political afterlife—his designation preserved one line of inheritance, but the accommodations made to the line he passed over helped furnish the claims and power that later threatened it.
