Yongle Emperor Zhu Di — Usurper of the Imperial Throne and Creator of the Cabinet and Forbidden City

Yongle Emperor (1360 — 1424), also known as Zhu Di and respected as Emperor Chengzu of Ming, was the third monarch of the Ming Dynasty in Chinese history.

Through a rebel war, he usurped the throne from his nephew, the Jianwen Emperor Zhu Yunwen (1377 — ?). 

Apart from his controversial ascension to the throne, he was a remarkable emperor who achieved great success on the battlefield, expanded territory, constructed the Forbidden City, supported Zheng He’s Voyages, promoted the flourishing of his empire, and ensured stable lives for his people.

Yongle Encyclopedia (Chinese name Yongle Da Dian), the largest paper encyclopedia in the world that includes more than 8,000 valuable books and over 370 million words, was compiled and published under his reign.

Prince Zhu Di and His Exceptional Military Successes

Zhu Di was the fourth son of Emperor Zhu Yuanzhang (1328 — 1398), the founder of the Ming Dynasty. 

After Zhu Di was born, he spent most of his time in the army since his father, Zhu Yuanzhang, was busy fighting with other forces. 

When he was 20, he was assigned as the Lord of Beijing City to defend the Ming Empire from nomadic regimes who had participated in many battles and had learned a lot through cooperating with the marvelous generals of Empire Ming.

When he and his other brothers were staying in their fiefs and defending the empire, their oldest brother, the crown prince Zhu Biao, was living with Emperor Zhu Yuanzhang and assisting him in managing the country. 

Zhu Di was an excellent marshal with remarkable military successes, a faithful son to his father, Zhu Yuanzhang, a well-behaved and kind brother to his older brother, and the crown prince, Zhu Biao.

However, to the nephews whom he had barely met before, he wasn’t quite kind.

The Ming Empire's First Complicated Transfer of Power

 

In Emperor Zhu Yuanzhang’s late years, his beloved first son Zhu Biao (1355 — 1392), also the perfect heir of the Ming Empire, passed away. 

At that time, Prince Zhu Di was the oldest living son of Emperor Zhu Yuanzhang, who made significant contributions to battlefields. 

However, Emperor Zhu Yuanzhang nominated Zhu Yunwen, the oldest son of Zhu Biao, as the new crown prince.

Considering Zhu Yunwen was still a talented teenager without military experience, it might be difficult for him to manage a newly built kingdom with many mature, exceptional marshals like Lan Yu.

Moreover, those exceptional generals were mostly allied through marriage with other sons of Zhu Yuanzhang.

 

Their close relationship with other princes and extraordinary military skills made them possible and capable of rebelling against young Zhu Yunwen’s reign and supporting a new emperor.

Therefore, Emperor Zhu Yuanzhang executed most of the contributive and exceptional marshals that he believed had the potential to rebel.

 

Meanwhile, he promoted many talented scholars to assist his beloved grandson, such as Fang Xiaoru.

However, the Ming Empire still needed a great commander to defend the northern border against nomad regimes; therefore, Prince Zhu Di was assigned to do this. 

From Potential Heir to Excluded King

Zhu Biao’s departure made Zhu Di the oldest living son of Emperor Zhu Yuanzhang, plus his exceptional military achievements. He once believed that he was likely to become the next heir.

But after Emperor Zhu Yuanzhang nominated his grandson Zhu Yunwen as the next heir, he frequently warned Zhu Di to be loyal, supportive, and respectful to his nephew. 

Later, his 21-year-old nephew, Zhu Yunwen, ascended to the throne and abrogated the authority and noble titles of five of Zhu Yuanzhang’s sons within a year.

 

Then, Zhu Di realized he would also be removed from power as a king with an independent army that might threaten the new emperor.

Subsequently, he feigned madness to deceive others while covertly sending spies to monitor his nephew, the emperor, as part of his preparations for rebellion.

Initiating the Rebel War and His Fortunate Success

Soon, Zhu Di allied with his other brave brother and initiated a rebel war against his nephew Emperor Zhu Yunwen; this was the Incident of Jingnan.

Zhu Di had participated in many battles before with his father; he also joined and led the seventh and eighth Northern Expeditions, the wars his father initiated against the former Mongolian regime.

 

Therefore, his army was very experienced and aggressive. 

On the contrary, his nephew, Emperor Zhu Yunwen was very young and had no military experience.

 

Moreover, most of the remarkable marshals of the central government of the Empire Ming departed because of sickness or had been executed by his grandfather Zhu Yuanzhang. 

Emperor Zhu Yunwen also wrongly gave his large, brave troops to an incapable general, who kept losing on the battlefields and then surrendered.

Consequently, after four years of intense wars, Zhu Di and his army arrived outside of Ming's capital city.

When Zhu Yunwen and many loyal soldiers were determined to fight back and wait for reinforcements, another prince and a cowardly general allied and opened the gate for Zhu Di.

Led by these traitors, he quickly got in and occupied the capital city of Nanjing.

To his surprise, his nephew emperor did not surrender, suicide, or negotiate.

Usurping the Throne from His Vanished Nephew Emperor

His nephew Zhu Yunwen, also known as the Jianwen Emperor, the rightful heir and the second emperor of the Ming Dynasty, known for his benevolent rule, set fire to his royal palace, the Forbidden City of Nanjing, and vanished along with his queen.

Some said he died in the fire, but no one found his body; others said he escaped through a secret tunnel and became a Taoist or a monk in different temples.

Either way, this emperor’s ending is still a secret in history.

Most of the official documents about Emperor Zhu Yunwen, along with himself, then disappeared as well. 

Many of Zhu Yunwen's loyal officials committed suicide after hearing about his failure.

Others who hadn't got the time to commit suicide and refused to surrender, such as famous scholar Fang Xiaoru, were all executed cruelly; tens of thousands of loyal and intelligent people were slaughtered.

Many of those faithful and knowledgeable officials' daughters were sent to brothels.

Similar Policy of the Yongle Emperor

Then, Zhu Di became the third emperor of the Ming Dynasty, respected as Yongle Emperor, Emperor Chengzu of Ming, or Emperor Taizong of Ming.

He moved the capital of the Ming Empire to Beijing city, built the Forbidden Palace, and re-established all his father's policies (because his nephew changed some), whether they were good or bad.

He re-established his father's military spy agency and established a monitoring system. 

Unlike his father, Emperor Zhu Yuanzhang, who built that agency to fight against corrupted officials, he used it to kill people against his throne.  

Zhu Di initiated the rebel war against his nephew because Emperor Zhu Yunwen wanted to remove power from him.

Therefore, after being enthroned as Yongle Emperor, he gave honorable titles and power back to all the kings, who were also his brothers and nephews. 

However, right after his reign was stable, he abolished power from most of them. Some were demoted to civilians, except Princess Zhu Changning, who frequently disrespected Zhu Di but stayed honorable for her entire life. 

Ultimately, he and his nephew were the same; they all desired centralized authority and needed to deprive the power of half-independent kings who were seen as potential threats. 

The only difference was that Emperor Zhu Di was more capable and decisive, and he succeeded.

Reign of the Yongle Emperor

Nevertheless, the Yongle Emperor was an outstanding monarch in Chinese history, despite the illegal and cruel means by which he ascended to the throne.

He invented the Cabinet System, which only included intelligent officials selected from the Imperial Examination; this agency soon became the most powerful authority in the Ming Dynasty.

Yongle encouraged agriculture, constructed many canals, and sent Zheng He on the Treasure Voyage six times, significantly contributing to communication among different cultures.

 

According to some gossip, Zheng He's secret mission was to track down the disappeared Emperor Zhu Yunwen. 

The achievements of the Yongle Emperor were indeed extraordinary. He initiated wars that significantly expanded his realm and hosted a grand military parade, which attracted numerous foreign monarchs and showcased his military might, with around 100,000 soldiers participating.

Military Activities on the Battlefields

Besides wars that Zhu Di had participated in when his father was the emperor after he got the throne, he led his army, marched northward to the desert, and attacked the remaining Mongolian forces five times. 

As an emperor, participating in wars in person so many times was relatively rare in the history of China.

 

Once, he even brought his beloved grandson Zhu Zhanji to the battlefront, trying to teach him how to command the army and fight. 

In the first three Northern Expedition Wars, the Yongle Emperor achieved big successes and further perished the enemies’ effective strengths.

Then the nomad armies kept hiding in the vast desert when Yongle marched there for the fourth and fifth times, so he didn’t achieve the military goals he had planned. 

Yongle Emperor died on his way home during the fifth Northern Expedition War.

Controversial Birth Mother

Yongle Emperor Zhu Di was sometimes criticized for his cruel behaviors toward his nephew, emperor Zhu Yunwen, and other brothers, and toward people against his throne.

His legality of being the emperor was questioned frequently, not only because he usurped the throne from his nephew, the legal heir that his father assigned. 

Another suspicious reason was if he was the birth son of the honorable Empress Ma Xiuying, the love of Emperor Zhu Yuanzhang's life.

In ancient Chinese culture, only descendants of one's wife could inherit the throne, honorable titles, etc., unless they didn't have sons.

 

Therefore, in general condition, sons of imperial concubines don't have the right to inherit the throne.

Zhu Di himself claimed that he was the biological son of Empress Ma Xiuying, the only honorable queen of Emperor Zhu Yuanzhang; therefore, his being the emperor was still reasonable.

But there are valid shreds of evidence showing that his birth mother was only an imperial concubine of Emperor Zhu Yuanzhang; this was why Zhu Yuanzhang passed the throne to his young grandson Zhu Yunwen, instead of the brave and mature prince Zhu Di.

However, after he got the throne, he erased everything about his birth mother and tried his best to show the public that he was the son of saint Queen Ma Xiuying.

 

In Nanjing city, there’s a royal temple named “Da Bao En.” Inside the temple was a 78.2-meter tall Porcelain Tower, constructed under the command of the Yongle Emperor to memorize his birth mother.

 

This fancy tower was destroyed during the Taiping Rebellion in the year 1856 and was reconstructed in 2007.

Legacy of the Yongle Emperor

Undoubtedly, the way that Yongle got the throne was destructive, and how he treated those loyal officials of his nephew Emperor Zhu Yunwen was exceptionally cruel.

 

Besides, he might have hidden the existence of his birth mother to support the legality of the throne. 

Besides that, the Yongle Emperor was an excellent monarch with outstanding military and governance skills in history.

He flourished, expanded his empire, and brought prosperous and stable lives to his civilians.

Like his father, he also had one and only beloved queen named Xu, whom he met and fell in love with when he was young.

 

Together they had three sons; the first boy, another good emperor, ascended to the throne after the Yongle Emperor departed.
