Sun Quan's Heir Crisis Breaks Wu Politics
Sun Quan had built Eastern Wu through patience and calculation, but his late-life succession struggle tore the court apart.
While Wei was falling under Sima control, Eastern Wu faced a different crisis.
It came from inside Sun Quan's own family.
Sun Quan had survived longer than Cao Cao, Liu Bei, and most of the founding generation. He had held Jiangdong through war, diplomacy, and patience.
But in old age, he failed at the one question every dynasty feared.
Who would inherit?
The Crown Prince Dies
Sun Quan's first crown prince, Sun Deng, had been widely respected.
He was careful, capable, and connected to important ministers. Many people believed he could stabilize Wu after Sun Quan.
But Sun Deng died before his father.
That death reopened the succession.
Sun Quan then made Sun He crown prince.
At the same time, he favored another son, Sun Ba, the Prince of Lu.
The problem was not only affection. It was status.
Sun Ba began to receive treatment close to that of the crown prince. His followers saw opportunity. Sun He's supporters saw danger.
The court split into camps.
Two Princes, Two Factions
Sun He's side included ministers who believed the crown prince's position had to be clear.
Sun Ba's side argued that he was also talented and deserved influence.
Once officials began choosing sides, the succession dispute became a political battlefield.
Memorials, accusations, rumors, and private alliances filled the court.
Sun Quan became suspicious.
Instead of ending the struggle quickly, he allowed it to deepen. Then, when the fighting became too intense, he punished both sides.
The result was disastrous.
Sun He was eventually deposed.
Sun Ba was forced to die.
Many officials connected to the dispute were executed, exiled, or destroyed.
Lu Xun Is Driven to Death
The crisis also hurt one of Wu's greatest ministers.
Lu Xun had saved Wu at Yiling and served as one of the state's most important commanders and statesmen.
He supported the principle that the crown prince's position should be protected. For him, unclear succession threatened the state.
Sun Quan grew angry at his interventions.
Repeated accusations and pressure fell on Lu Xun. He died in grief and frustration.
This was more than the fall of one minister.
Lu Xun represented the older Jiangdong elite that had helped Wu survive. If even he could be driven down by palace suspicion, every official understood the risk.
Sun Liang Becomes Heir
After destroying both Sun He and Sun Ba's positions, Sun Quan chose a much younger son, Sun Liang, as heir.
This solved the immediate dispute but created another danger.
Sun Quan was old.
Sun Liang was young.
A child ruler would need regents, and regency meant another struggle over who held real power.
Wu had already lost trust in its court. The succession crisis had consumed talented officials, divided families, and weakened the political class that should have protected the next reign.
Sun Quan had spent decades building a state.
In his final years, he left that state with a fragile child emperor and a wounded court.
The Founder's Shadow
Sun Quan died in 252.
He had ruled Jiangdong for more than half a century, first as warlord, then king, then emperor.
His achievements were enormous. Without him, Eastern Wu would not have survived between Wei and Shu.
But his last political decision left deep damage.
The young Sun Liang came to the throne.
Around him stood powerful ministers, military families, and old resentments.
Next, the man called Little Zhuge steps forward to govern Wu for a child emperor.
