Emperor Han Jing promised his younger brother Liang Wang to pass on the throne to him. Why did he back out later?

In feudal society, the sibling inheritance system is very dangerous, and the father-son inheritance system is more conducive to the stability of the empire. Therefore, no matter how Han Jingdi promised Liang Wang, he had to break his word if he wanted to achieve political stability in the Western Han Dynasty.

When Han Jing promised his younger brother Liang Wang to succeed to the throne, it coincided with the Seven Kingdoms Rebellion in the Western Han Dynasty. Emperor Jing of Han Dynasty did not expect that his separatist regime of Wu would cause a mutiny of the King of Wu. What he didn't expect was that Wu turned against six other vassal States. Due to the lack of preparation, the seven countries once again threatened, and the Western Han Dynasty was once in danger. At this time, Liang Wang led thousands of miles to escort his younger brother Emperor Han Jingdi, which was a timely help. Han Jingdi was very moved and promised his younger brother Liang. Han Jingdi was also very helpless. After all, in the early days of the Seven Kingdoms Rebellion, the Western Han Dynasty was at a disadvantage. Han Jing did not hesitate to kill Chao Cuo, who suggested that he cut off the vassals, in order to please the Seven Kingdoms and let them retreat. Unfortunately, the rebellion of the Seven Kingdoms remained, and the troops of the Central Court were losing ground. If Emperor Han Jingdi was really defeated by the Seven Kingdoms, he would not say that his children were young and unable to fight against the Seven Kingdoms. However, if an adult brother inherits his throne, it is still possible to set things right, so he will agree to Liang Wang's throne.

However, the rebellion of the Seven Kingdoms was later put down by the central government, and the central government of the Western Han Dynasty was stable again, and the emperor Han Jing remained the emperor. Although Liang Wang played an important role in the Seven-State Rebellion, if Liang Wang is still named as Chu Jun, the political situation in the Western Han Dynasty will be turbulent again. First of all, Liang Wang was a vassal king, and the Seven Kingdoms Rebellion was because the vassal king had too much power and wanted to replace the central government. In the case that Emperor Han Jing had children, if the king of San Francisco was also named Chu Jun, it would be ridiculous to quell the rebellion of the Seven Kingdoms, because the final result was the same, and the princes became the winners, then there would be a situation in which the throne could be inherited by the princes and all the princes in the world were eligible to inherit, and the system of establishing official positions and establishing the length would become a joke. The better result was the chaos in the Western Han Dynasty when the throne was handed over, and the almost result was that the Western Han Dynasty was chaotic at any time. In short, even if Han Jing wanted to pass on his throne to his younger brother Liang Wang, the ministers and people of the Western Han Dynasty would not allow such a thing to happen.

Moreover, Emperor Han Jingdi is also a father with children. Since ancient times, as the saying goes, ruthlessness is always in the emperor's house. For the throne, brothers often kill each other, let alone their nephews. If he passes the throne to his younger brother, will Liang Wang be able to accommodate his children when he becomes king one day? Maybe all his sons will be killed, and then he will really become an orphan. In ancient times, nothing was more sad than the death of a child. Even if Liang Wang can control his son, who can guarantee that his son has no intention of fighting? In the end, either all the children died or uncles killed each other. No matter how you look at it, it is a human tragedy. Whether in public or in private, Emperor Han Jing can't move to Liang Wang, so he has to go back on his word.
