Not only because of lewdness, but also because of concubinage of ancient dignitaries.

In ancient times, dignitaries took concubines not only because of lewdness, but also to carry on the family line and increase the population of the country. We all know that three wives and four concubines were allowed in ancient times, because men were superior to women in ancient society, and women could not get enough respect. Many people think that the reason why ancient dignitaries took concubines was simply because of lewdness, but in fact, lewdness is just one aspect. I think men are lewd, only some. Monogamy was really rare in ancient times.

In fact, the most important thing in ancient times was to carry on the family line. The medical conditions in ancient times were far less good than ours now, so it was difficult to give birth in ancient times. Not all children could be born smoothly, even if they were born, they might die of congenital malnutrition, and there were many women who died during childbirth. Since the survival rate of children was low, the best way was to marry more concubines and have more children. Due to the difficult living conditions in ancient times, it is difficult for ordinary families to take good care of pregnant women after giving birth, and they are prone to many gynecological diseases and may not be able to have children in the future.

So ordinary families may be willing to have children, but they can't have three wives and four concubines, because life is not very rich, and there is no extra money to marry concubines. But the country needs people, because the society was still in turmoil at that time, and wars often occurred. In order to have enough people, the best way is to have children. There is another reason for dignitaries to take concubines, which is to strengthen the family's power, the so-called strong alliance.

These are the reasons why dignitaries take concubines. Now that our living conditions are good, society is progressing, and men and women have become equal, we have abandoned the tradition of three wives and four concubines for men.
