When Emperor Yang Jian of Sui married Empress Dowager Jia luo, the two agreed to "swear not to have a son of another birth." Since then, Yang Jian and Dugu Jialuo have had five sons, namely the eldest son Yang Yong, the second son Yang Guang, the third son Yang Jun, the fourth son Yang Xiu, and the fifth son Yang Yu. After Yang Jian established the Sui Dynasty, he boasted to his ministers: "In the previous life, the Son of Heaven, drowning in the misfortune of the concubines, was divided into disputes, and then there was a abolition, or a kingdom that was destroyed; there was no Concubine, and the five sons and the same mother could be described as true brothers. ”
Emperor Wen of Sui was optimistic that his sons were all born to the same mother, so there would be no civil unrest in the Sui Dynasty. However, the incident slapped Emperor Wen of Sui four times, and it turned out that the struggle of the Sui Dynasty royal family was more intense, and before Emperor Wen of Sui's death, the four sons were involved in the struggle for the throne. Later, none of Emperor Wen of Sui's five sons actually died well! So how did these five sons of Emperor Wen of Sui die?
Eldest son Yang Yong. As the eldest son of Emperor Wen of Sui, Yang Yong was naturally made crown prince, and he was "generous and generous, willing to be kind, and unpretentious." However, Yang Yong has a problem, his life is more luxurious, it is no wonder, after all, he was born in a rich family since he was a child. At the same time, there were also many concubines in Yang Yong's mansion. It is reasonable to say that this is not a big problem, but in the eyes of Emperor Wen of Sui and Dugu Jialuo, this has become Yang Yong's "evil deeds".
The second son, Yang Guang, saw this opportunity and tried his best to express himself in front of his mother, and at the same time, he co-opted the courtier Yang Su and actively competed for the throne. Under the frame of Yang Guang and Yang Su, Emperor Wen of Sui deposed Yang Yong as crown prince. In 604, Emperor Wen of Sui died violently, and Yang Guangbi did not mourn, and in the name of Emperor Wen of Sui, he ordered that the deposed prince Yang Yong be executed. Yang Yong's ten sons were exiled to Lingnan, the eldest son Yang Yu was poisoned halfway through, and the rest of the sons were executed by local officials.
Second son Yang Guang. Yang Guang deliberately sat on the emperor's throne, but because he was so happy and did not know how to cherish the people's strength, the world was in chaos, and peasant uprisings and rebellions broke out in various places. In 616, Yang Guang left Luoyang and came to Jiangdu. At that time, the situation in the world was out of control, and he planned to divide Jiangnan and maintain half of the country. However, in 618, the Sui Dynasty broke out in the Jiangdu Rebellion, and the Sui Emperor was strangled to death by his subordinates.
The third son, Yang Jun. At the beginning, Yang Jian still liked his third son Yang Jun, "Gao Zu smelled and was very happy, and the next book rewarded Yan." However, it did not take long for Yang Jun to begin to live an extravagant and lavish life, and even "violated the system and paid for interest", which made the people's resentment boil. At the same time, Yang Jun, because he liked other concubines, was poisoned by his own princess Cui Shi. In 600, Yang Jun was poisoned and died, and Yang Jian symbolically cried a few times, while categorically refusing to erect a monument for Yang Jun.
The fourth son, Yang Xiu. Yang Xiu's appearance was dignified, "beautiful beard, multi-martial arts", and the civil and military officials of the imperial court were very much in awe of him. Yang Jian once said to Dugu Jia luo: "Xiu will end in evil." I am free to worry, and even my brother will rebel. But Yang Jian thought wrongly, during his reign, Yang Xiu began to recruit soldiers and buy horses, "the carriage and horses were served, and they were intended to be the son of heaven." In 602, Yang Xiu's witchcraft was exposed, and Emperor Wen of Sui was so angry that he even wanted to execute Yang Xiu, and finally deposed him as a Shuren. During the change of Jiangdu, Yang Xiu was also killed.
The fifth son, Yang Yu. As the youngest son of Emperor Wen of Sui, Yang Yu was deeply favored by his parents, so he was named the King of Han and ruled over the original Northern Qi homeland. Yang Yu witnessed the struggle between several brothers, and in order to protect himself, he began to accumulate strength. After the death of Emperor Wen of Sui, Yang Guang recruited Yang Yu in the name of his father, but Yang Yu categorically refused and directly raised an army to rebel. However, Yang Yu's ability was limited, and the rebellion was eventually put down. In 605, Yang Yu was imprisoned by his second brother and died, and finally Chinese New Year's Eve years old.
