Why did Zhou Wuwang entrust an orphan to Zhou Gongdan instead of Jiang Ziya?

Zhou Wuwang chose Zhou Gongdan over Jiang Ziya for many reasons. Because of the establishment of the Zhou Dynasty, it can be said that Jiang Ziya made great contributions to this. Once Zhou Wuwang dies, it will be difficult for anyone to subdue Jiang Ziya. It can be said that if Jiang Ziya is the only one left in Zhou Wuwang, then no one can balance Jiang Ziya. At that time, Zhou Wuwang didn't trust Jiang Ziya very much. Otherwise, Jiang Ziya, one of the greatest contributors to the establishment of the Zhou Dynasty, would not be poor in his fiefs.

Moreover, when the Western Zhou Dynasty was established, the patriarchal clan system was the core system of the country, and the Duke of Zhou was Zhou Wuwang's brother, which could be said to be a deeper blood relationship. It can be said that Duke Zhou was a relative and Jiang Ziya was an outsider, and at that time, he paid great attention to blood relationship, so it was much better to entrust Duke Zhou with an orphan than Jiang Ziya. Although judging from the prestige and quality of Duke Zhou and Jiang Ziya, both of them could serve as political leaders' assistants, at that time, Jiang Ziya was about 70 years old, so it can be said that at this age in ancient times, he was already a long-lived old man. It can be said that Jiang Ziya is in danger of death at any moment. If he is left alone, if he dies in the process of assisting the government, it will cause national unrest.

It can be said that from these aspects, it is far better to choose the Duke of Zhou to entrust an orphan to Jiang Ziya. Moreover, at that time, the ability of Duke Zhou was very outstanding. It can be said that some systems on which the Western Zhou Dynasty depended were formulated under the auspices of Duke Zhou, who was not greedy for power. When the monarch was in power, he was decisively restored to power.

Moreover, because Jiang Ziya was in charge of the military power in his early years, his ruling ability was very strong, which can be said to have won the hearts of the people and his influence spread all over the country. It can be said that Zhou Wuwang is very afraid that he will reap the consequences after his death. However, because he is a founding hero, there is no reason to get rid of him, otherwise he will easily end up being blamed for killing donkeys. Therefore, entrusting orphans to Duke Zhou is Zhou Wuwang's only choice.
