In the ancient feudal dynasty, emperors generally had multiple wives, and few of them could dedicate themselves to each other. However, there are always exceptions. In the Ming Dynasty, an emperor practiced monogamy. This emperor is Zhu Shitang, the emperor of the Ming Dynasty.

I think that the reason why Zhu Shitang of Ming Xiaozong can follow monogamy is related to his own experience, that is, the tragic situation of his childhood made Ming Xiaozong hate harem fighting and refused to marry many concubines.

Zhu Shitang's childhood life was very bumpy. From his unborn to his accession to the throne, he was always shrouded in the shadow of Wan Guifei for eighteen years. During this period, because his father Ming Xianzong Zhu Jianshen was too weak to control Wan Guifei, Wan Guifei was unscrupulous in the harem and even dared to force his pregnant concubine to terminate her pregnancy.

It was under the control of Wan Guifei that many concubines in the harem could not give birth to a son and a half for Zhu Jianshen for many years. And Zhu Shitang's mother Jishi was not even a concubine at that time, but a shopkeeper. After learning that she was pregnant, Wan Guifei sent someone to kill Zhu Shitang twice.

Later, even though Zhu Shitang regained her birthright and was established as the Crown Prince, she was still persecuted by Wan Guifei. At the worst, his crown prince was almost abolished. If it weren't for the Taishan earthquake, Ming Xianzong was frightened, and Zhu Shitang couldn't even inherit the throne.

I believe these things have done great harm to Zhu Shitang's mind and made him unwilling to let his children live in such an environment again. So he didn't marry other concubines all his life, only one wife, his wife, Queen Zhang, and they respected guests until the death of Emperor Xiaozong of Ming Dynasty.

The practice of Emperor Xiaozong of Ming Dynasty seems to be devoted now, but it was very unfavorable to the Ming Dynasty at that time. It was also because of his persistence that the throne was not passed down in his branch. When Zhu Houzhao, the son of Emperor Xiaozong of Ming Dynasty, died of illness, he had to choose his cousin Zhu Houzong as his successor.

To sum up, it is my personal opinion on the implementation of "monogamy" in Ming Xiaozong, hoping to help you.
