How did eunuchs become Eunuchs?

Eunuchs were typically created through castration, which was often performed on young boys, either as a punishment, for the purpose of serving in royal courts, or to fulfill specific societal roles. In many cultures, eunuchs were valued for their loyalty and ability to hold positions of trust, particularly in harems or as guardians of women. The practice dates back thousands of years and was prevalent in various civilizations, including ancient China, Persia, and the Byzantine Empire. The motivations for becoming eunuchs varied, ranging from forced castration to voluntary submission for social advancement and stability.
