Why did the rulers in ancient China have three wives and four concubines, while European countries could only have one wife?

Ancient rulers could marry many women around them, and later there was a saying that they had three wives and four concubines. The marriage system in most countries is monogamous, which is fair to both men and women.

Since ancient times, many men have wanted to have wives and concubines. The idiom used to say that men have wives in groups is three wives and four concubines. For many people, three wives and four concubines are just a wish, and they are often talked about by many people. Ancient people married three wives and four concubines in order to carry on the family line. Because the living conditions in ancient times were not very good, the fertility rate and survival rate were relatively low. There were three wives and four concubines because men were superior to women in the social system at that time, which made the grades of men and women even different. Later, there were more men, and women could only live a lifetime.

Three wives and four concubines in ancient times were mainly a marriage system in feudal times. This is very unfair to women. It's normal for men to remarry, and it's a disgrace for women to remarry. Both men and women are very humble, and women can only rely on men, which is the result of the social system. Among the three wives and four concubines, the third wife has the final say in daily life, and the fourth concubine only helps the third wife. They used to be a very friendly family, but they should be treated differently because of their status. There should be no problem for mistresses, but for concubines, they can't feel the warmth of family.

In ancient Europe, even if men were romantic, there were countless mistresses, and even mistresses gave birth to children for themselves, but in law, concubinage was never allowed. In other words, people in ancient Europe have strictly observed monogamy, and there is no possibility of concubinage at all. The emergence of monogamy in Europe was stipulated by the rulers in order to safeguard their inheritance rights and property. In short, monogamy in Europe is an agreement between rulers and religions, and the system of checks and balances between them continues to exist.
