Zhu Di

Biodata

Background / History

Zhu Yuanzhang invested Zhu Di as Prince of Yan at age eleven, in the third year of Hongwu. At twenty-one, he took up residence in Beiping, the former Yuan capital and a major defensive position against the remaining Yuan forces beyond the passes. Alongside other frontier princes, he became one of Great Ming’s northern guardians 10.

Zhu Di learned warfare under Li Wenzhong in his youth. He later won complete victories in northern expeditions during the twenty-third and twenty-eighth years of Hongwu, greatly increasing his prestige and his father’s confidence in him. After the deaths of Zhu Biao, Zhu Shuang, and Zhu Gang, he became the foremost of the enfeoffed princes 10 15.

A month before Zhu Yuanzhang’s death, Zhu Di was ordered to command the armies preparing to defend Kaiping. Instead of receiving marching orders, he learned that his father had died. Barred from attending the funeral, he kowtowed toward the capital from Huai’an and returned to Beiping grieving and resentful. Dao Yan subsequently urged him to prepare against the possibility that the new emperor would abolish the princes’ fiefs 10.

Appearance

Zhu Di has an imposing bearing marked by visible arrogance 17.

• Facial features: Long, thick eyebrows, a straight nose, deep and bright eyes, and a full beard 17.
• Court dress: An imperial prince’s ceremonial robes and crown 16.
• Military dress: Armor and a battle robe when confronting the Three Guards 34.
• Mourning dress: White robes and a white sash upon arriving at Three Hills Gate after his father’s death 15.

Personality

Zhu Di is ambitious, proud, and unwilling to relinquish his claim to a greater future. His initial refusal to bow to Zhu Yunwen reflects more than personal resentment: acknowledging the emperor would weaken any later argument that the succession rested on a forged edict. Even after kneeling, he privately treats submission as a temporary concession rather than surrender 16 17.

His ambition is tempered by caution. He recognizes the court’s numerical superiority, the distance between Beiping and Nanjing, and the logistical demands of rebellion. He can conceal hostility behind courtesy, seek help from advisers, and retreat when circumstances become unfavorable. He also acknowledges Zhu Yunwen’s governing ability despite their rivalry 15 17 34 39.

Recognition matters deeply to him. When Dao Yan proposes serving the emperor’s larger undertaking, Zhu Di objects that history would remember Zhu Yunwen rather than himself. His eventual submission follows both his recognition that rebellion cannot succeed and the invitation to participate in an undertaking extending beyond the struggle for the throne 42.

Story Role / Major Arcs

Summons and Court Confrontation

Zhu Yunwen reverses the earlier exclusion and summons Zhu Di to the capital. Following Dao Yan’s advice, Zhu Di publicizes his journey to make any move against him politically costly. In Yangzhou, Li Zengzhi encourages him to consider rebellion under the pretext of defending the founding emperor’s institutions 1 10 15.

At court, Zhu Di initially refuses to bow. Zhu Yunwen treats the matter as court protocol rather than a family grievance, leaving him little room to justify his defiance. Zhu Di finally kneels, but retains his imperial ambitions and begins cultivating favorable public opinion through visits across Nanjing 16 17 18.

Loss of Advisers and Military Influence

Zhu Yunwen removes Dao Yan from Beiping under the pretext of having him pray for the empress dowager, then takes Ma Sanbao into imperial service. Zhu Di also refuses responsibility for implementing the new military policies, allowing Ping An to administer them around Beiping while the Three Guards remain excluded 21 22.

At the Mid-Autumn banquet, the emperor repeats a phrase from Zhu Di’s private meeting with Li Zengzhi. Zhu Di concludes that his ambitions and associates are already known. His sons debate submission and rebellion, but he postpones a decision until their return to Beiping 24.

The Three Guards Crisis

The New Army policy wins soldiers over to the court through improved provisions and family benefits. When Ping An reveals that Zhu Di himself rejected the policy for the Three Guards, their resentment turns against the prince. Zhu Di returns to Beiping on the fourteenth day of the ninth month to find his former support badly eroded 31 32 33.

With Jin Zhong’s advice, Zhu Di temporarily restores loyalty by arguing that the promised benefits are financially unsustainable. He then establishes the concealed weapons workshop and prepares for a future opening 34 35.

Defections and Feigned Madness

More than five hundred guardsmen defect to Ping An, causing Zhu Di to collapse from anger and anxiety. Ping An subsequently surrounds the guards’ camps with thirty thousand troops and arrests Zhang Yu and Zhu Neng on allegations of treason 38 39.

Zhu Di agrees to introduce the New Army policy while waiting for another opportunity. He then pretends to have gone mad, including a public incident at the river. By the end of the eleventh month, Zhu Gaochi has accepted the policy on his behalf, but its accompanying ideological instruction further strengthens the guards’ loyalty to Great Ming and the emperor 39 40 41.

Allegiance to Zhu Yunwen

Dao Yan returns to Beiping as a Hanlin Academy scholar and exposes the madness as a deception the emperor anticipated. After reading Cat Theory, Zhu Di recognizes that Zhu Yunwen is gaining support among soldiers, scholars, commoners, and merchants. He concedes defeat and offers to go bound to the capital for judgment 42.

Dao Yan also conveys the emperor’s invitation to join an unprecedented undertaking and describes his world map. Zhu Di ultimately acknowledges Zhu Yunwen as emperor and vows to follow him, redirecting his ambitions away from rebellion 42.
