China's first emperor by vote, creating a generation of prosperity, becoming an emperor in ancient times, the emperor generally adopted a hereditary system, if the father is the emperor, then after the death, the emperor will pass to the prince, and generally are the eldest son. But problems are easy, and there are many people in history who have often had fratricide for sanitation.
But in fact, there are still many unexpected situations in history, for example, if an emperor has no descendants, then it will be passed on to the eldest son of his brother, but in the Han Dynasty, there was a special situation, that is, after Liu Bang died, Lü Yan monopolized power, it can be said that all the emperors at this time are puppets.
At this time, all the people of the Lü family became kings with different surnames. But at that time no one dared, I looked at this order, so at this time there were three puppet emperors, and after Liu Zhi died, the good days of this family also came to an end. The final outcome of the Lü family was very tragic, but at this time no one could inherit the throne, because at that time the emperors were all fathers and sons, but at this time there were three puppet emperors, and none of them had descendants, so at this time it was recommended to take a vote to solve the problem.
So at this time, there was the first emperor, who was elected by vote, and this emperor was Liu Heng. Although Lü Zhi helped Liu Bang at that time, because at that time Liu Bang was only a very small official, at this time Lü Zhi had been helping, Liu Bang could be said to be a very good xiannei helper, but after the establishment of the Han Dynasty, what liu Bang lacked was a confidant.
Therefore, Liu Zhi also knew Liu Bang's bitter feelings, so he joined forces with others to kill Han Xin, in fact, if Liu Bang did not agree to this matter, they did not dare to do so at all, so Han Xin's death must be related to Liu Bang. So there were a total of 4 candidates, the first of which was Liu Bang's brother, but he obviously could not become the emperor, because his ideas were very similar to Liu Bang's, if he became the emperor, then all the people of the Lü family would be killed and would face many problems.
The second person was Liu Xiang, who was the eldest grandson of Liu Bang. In fact, according to the general principle, he is the most qualified person. The third person is Liu Hao, who is Liu Bang's nephew, and the fourth person is Liu Heng. Of these four, Liu Hao was eliminated first because Liu Bang had both sons and grandsons, and it was impossible for his nephew to succeed to the throne.
So let's look at Liu Bang's younger brother, at this time he is very old, if he becomes emperor, I am afraid that he will die in two years, which is also not OK, so now there are only two people left, so he voted again. Liu Ze became a judge at this time, and the reason why he did this was because after doing so, other Han Dynasty projects would not have any ideas. Liu Xiang imprisoned Liu Ze and also took away his military power, so after receiving such humiliation, he certainly could not give up, so in the end Chen Ping proposed that Liu Heng succeed to the throne.
