Why the Prince of Dai Was Chosen as Emperor Wen

In the last episode, Empress Lu had pushed the court so far into her own hands that the palace almost seemed to have forgotten the Liu surname altogether.

That was sustainable only while she lived.

The moment she died, the pressure between the Lu clan and the Liu imperial house would burst upward.

While the Kings of Zhao Kept Dying, the Prince of Dai Stayed Quiet at the Edge

During Empress Lu's years of power, members of the Liu house lived under growing pressure. The kingship of Zhao became an especially dangerous place. Liu Ruyi died. Later Liu You was summoned to Chang'an and starved to death. Then Liu Hui became king of Zhao and eventually killed himself under pressure tied to Lu family marriage politics.

Three kings of Zhao died one after another.

In the middle of that violence, Liu Heng, prince of Dai, remained in the far north almost as if he hardly existed.

His mother, Consort Bo, was quiet and uncompetitive. Liu Heng himself was known as mild, cautious, and restrained. Dai was a frontier state near the Xiongnu and therefore distant from the poisonous center at Chang'an.

That distance helped him survive.

Empress Lu Did Consider Moving Him, but He Refused the Trap Politely

At one point Empress Lu wanted to transfer Liu Heng to Zhao.

On the surface, this looked like elevation. Anyone paying attention knew better. Zhao had become a place where kings died.

Liu Heng understood the danger. So he answered in a way that neither resisted bluntly nor walked into the pit. The frontier, he said, still faced the Xiongnu. He wished to remain in Dai and guard the border for the court.

The reply was obedient in tone and evasive in substance.

Empress Lu let the matter drop and gave Zhao instead to members of the Lu clan.

Liu Zhang Was One of the First to Say Openly That the Lu Clan Was Not Liu

Opposition to the Lu rise was not entirely silent.

One of the most striking figures was Liu Zhang, marquis of Zhuxu and son of Liu Fei of Qi.

At a palace drinking banquet, Empress Lu ordered him to serve wine. He then asked for permission to enforce order according to military discipline. She agreed.

While drinking, he sang a song whose meaning was unmistakable: when planting a field, any shoots not of one's own line should be pulled up.

That was nearly the same as pointing at the Lu clan and saying they were not true Liu stock and should one day be cleared away. Soon after, when a drunken Lu clansman broke protocol, Liu Zhang pursued and executed him under the pretext of military order.

Empress Lu swallowed the insult, but the message had been sent.

Chen Ping and Zhou Bo Were Not Natural Allies, but the Crisis Pushed Them Together

The minister who best grasped the danger at court was Chen Ping.

He knew that if the Lu clan advanced much further, open conflict with the Liu house would eventually come. Yet he also knew that strategy alone would not decide that day. In the end, the side with troops would matter.

That meant Zhou Bo.

Their relationship was not naturally warm. Men from the old Pei circle had once distrusted Chen Ping as too clever and slippery. Still, men like Lu Jia and Li Ji helped show the necessity. In stable times, the chancellor matters most. In danger, the general matters most. If the two were divided, neither the court nor the dynasty would survive a real crisis.

So Chen Ping lowered himself, offered courtesy and gifts, and repaired relations with Zhou Bo. One held political intelligence. The other held military weight. They needed each other.

When Empress Lu Died, the Lu Clan Inherited Her Fear as Much as Her Power

In the seventh year of Empress Lu's rule, her health declined.

Before dying, what she worried about most was not the empire in general, but whether the Lu clan could remain secure after her.

So she made arrangements: Lu Lu was to control the northern army, Lu Chan the southern army, and both were warned never to give up military command after her death because the ministers would move against them.

Then she died.

The hand holding down the lid was gone.

The First Key Was Not Open Battle, but Deceiving Lu Lu Out of the Northern Army

The Lu side knew danger was coming and wanted to strike first if possible. But everything depended on control of troops inside Chang'an.

So Chen Ping and Zhou Bo did not begin with heroic assault. They began with deceit.

The crucial intermediary was Li Ji, whose family had ties to Lu Lu. He persuaded Lu Lu that once the empress was dead, continuing to hold the northern army would only make all under heaven suspicious. Better, he said, to surrender command and return peacefully to one's kingdom.

The advice sounded protective.

It was a trap.

And Lu Lu believed it.

Once the Northern Army Was in Hand, the Attack Could Begin

With the northern army transferred, the balance changed instantly.

Zhou Bo took command. Liu Zhang helped guard the palace gates so that Lu Chan could not enter and seize the initiative. Lu Chan still did not realize how far matters had shifted and moved restlessly around the palace area.

Liu Zhang judged the moment right and attacked.

Lu Chan fled in confusion and was eventually killed. After that, Zhou Bo understood that the most dangerous core had broken. The rest became cleanup.

The court moved quickly. Members of the Lu clan were arrested and killed in rapid succession. Within days the political order built by Empress Lu had been smashed.

This was the disorder later remembered as the uprising of the Lu clan.

After the Lu Clan Fell, the Child on the Throne Could Not Remain

Yet removing the Lu clan did not solve the whole problem.

There was still an emperor.

The boy then seated on the throne had been installed under Empress Lu and was politically inseparable from her arrangements. Once the Lu clan was gone, he could not stay.

So Chen Ping, Zhou Bo, and the others began discussing who should replace him.

Several possibilities raised concerns. Some had overly strong maternal families. Some were too fierce in temperament. Some were too close to Chang'an and too likely to generate new instability.

In the end, the same name drew agreement.

Liu Heng of Dai.

Liu Heng Was Chosen Not Because He Was the Strongest, but Because He Was the Steadiest

He was not the most magnificent of Gaozu's sons.

His kingdom lay far away. His military resources were limited. His maternal family was not powerful. By sheer strength, he was not the obvious choice.

That was part of the attraction.

He was a legitimate son of Gaozu. He was mature, moderate, and known for kindness and filial conduct. Most importantly, he did not arrive with a maternal clan ready to overpower the ministers the moment he reached the throne.

So the court decided to invite him to Chang'an.

When He Heard He Was Being Offered the Empire, His First Reaction Was Fear

When the envoys from Chang'an reached Dai, Liu Heng did not greet the news with joy.

That was not false modesty. He knew perfectly well how many people had died in Chang'an over the previous years. He also knew that the men now inviting him were seasoned founders, not harmless servants.

So his first thought was simple: could this be a trap?

He summoned advisers. Some urged him not to go. Others, especially Song Chang, argued that the empire remained fundamentally the Liu house's empire, that the ministers could not easily overturn that fact, and that the invitation followed both legitimacy and general sentiment.

Even then, Liu Heng remained cautious.

He Moved Only After Testing the Road Step by Step

First he sent his uncle Bo Zhao to sound out Zhou Bo and verify intentions. The report came back reassuring.

Still he did not relax completely.

On the journey toward Chang'an, he halted near Gaoling and sent Song Chang ahead again to inspect the reception at Wei Bridge. Only after confirming that Chen Ping and the senior ministers were waiting there in proper formal order did he continue.

Faced with the greatest opportunity in the world, he still advanced as a cautious man, not an eager one.

At Wei Bridge, the Relationship Between the Prince of Dai and the Court Was Publicly Fixed

At Wei Bridge, Chen Ping, Zhou Bo, and the other great officials knelt and welcomed him.

This was more than courtesy to a regional prince. It was a public declaration that Chang'an now recognized him as the coming ruler.

Zhou Bo tried to hand over the imperial tally privately as a sign of closeness, but Song Chang immediately objected. Public business, he said, must be handled publicly. A king has no private business in such a matter.

The formal line was preserved.

After the Ritual Refusals, Liu Heng Finally Took the Throne

Once installed in the residence prepared for him in Chang'an, Liu Heng received the formal petitions asking him to become emperor.

He refused several times in ritual humility, claiming insufficient virtue. The ministers petitioned again and again. Every stage had to be observed.

Only then did he accept.

The child emperor set up by Empress Lu was removed from the palace, and Liu Heng became the third emperor of Han.

He is known to history as Emperor Wen.

Choosing Liu Heng Did More Than Change the Emperor

With his accession, Chang'an ceased to live under the Lu shadow.

More importantly, the dynasty's path changed. The man who had survived by caution, distance, and restraint was now placed at the top of the empire.

That choice would shape Han for decades.

In the next episode, we turn to how Emperor Wen began ruling and how the long era later remembered as the Rule of Wen and Jing started to take form.
