Why do Turkish harem only want lean black people to be eunuchs?

Everyone has heard of the Ottoman Turkish Empire, an ancient civilization that once flourished. So, do you know that only thin black people in Turkish harem are eunuchs? Why is this?

The first reason is to ensure the purity of blood. If there is a black child in the harem, then the child's pedigree must be impure, and it is very convenient to find out which child's pedigree is impure. That's a good idea, too, but what if women's genes are bigger and they are not inherited from men's skin color genes? This is a semi-probability, so, will this be muddled through? Is this what the monarch wants?

The second reason is that there were some mistakes in the previous castration. One reason is that the medicine in Turkey was not as developed as ours at that time, which led to some people's incomplete phenomenon, and therefore the phenomenon of improper bloodline appeared. To make up for this result, I came up with the idea of using black people as eunuchs. Do you think this monarch has foresight? The idea of this monarch is also drunk. The purpose of many concubines is not to have children. Of course they are willing to have children with the monarch, but the monarch is often unlucky. What should I do? Women also have physiological needs! Find slaves to solve their desires, as long as they are not born.

It is conceivable how chaotic the harem would be at that time, but the monarch's mind was still very broad. As long as there are no children, I won't bother you. You mean concubines It seems that the relationship at that time was a bit similar to some of our wedding stars now, each playing his own game, but there were nominally husband and wife. Of course, it is still possible for two people to play together.

Do you think there will be dark-skinned children in Turkish harem?
