A eunuch is a man who has been castrated, often early in life, typically for specific social or political purposes. Historically, eunuchs were commonly employed in royal courts as guards, servants, or advisors, particularly in ancient civilizations such as China, Persia, and the Byzantine Empire. Their status often exempted them from certain societal norms, allowing them to hold positions of influence while remaining outside the competition for power through traditional means. In some cultures, eunuchs were also believed to possess unique qualities, such as loyalty and trustworthiness.
