Among the princes of the Qing Dynasty, the most famous one was Dourgen. Dourgen made outstanding achievements in his life and was in power in the ruling and opposition parties. He took over the position of regent from the then prince.

Dourgen's road to power was not smooth, and there were many competitors in the middle that embarrassed Dourgen, so I won't list them one by one.

Here I mainly mention the representative figures. The representative here is the eldest son of Qing Taizong, Hao Ge. He followed his father, Huang Taiji, and moved to Mongolia, Chahar, Erdos and other departments, and made many military achievements.

In AD 1636, after Huang Taiji proclaimed himself emperor, he made Haug the prince of Heshuo Su, in charge of family affairs. Soon after, he was demoted to Baylor because he revealed his feud with Yue Tuo to Huang Taiji.

Later, he followed Huang Taiji to attack North Korea. Haug led the army to pursue the remnants of the king of Korea. He traveled all night and finally caught up with him and defeated the North Korean army in one fell swoop.

In A.D. 1642, Haug made great contributions in the Jin Song War, and Huang Taiji restored Haug's original title.

Huang taiji, who died in a.d. 1643, died suddenly. Because of his sudden death, he left no testamentary edict before his death, not to mention the issue of heirs.

The battle for the throne has also entered a white-hot state. The objects of the Eight Banners are divided into two factions. Both the original yellow flag and the yellow flag following Huang Taiji advocated the establishment of Haoge. First of all, because Hao Ge is the eldest son of Huang Taiji, he has certain military exploits.

Zheng Qinwang Gilhallang, who has mastered the blue flag, also tends to recommend Haug to the throne, and Haug also has his own blue flag.

In addition, Dai Shan, who was respected in the Eight Banners at that time and was in charge of the red flag and flag-setting ceremony, also tended to inherit the throne from Hogg.

Haug has the support of six banners, and Haug has an absolute advantage in military strength. Dourgen was highly valued by Huang Taiji when he was alive because of his outstanding military exploits and outstanding ability. There are also many royal families who support Dourgen in the Eight Banners.
