Prima Nocta is a word used to describe the act by rulers of a country, religion, or empire who demanded from his people the right to sleep with women on her wedding night.
This historically occurred in many cultures, including ancient Rome. It contributed towards the tradition of rape as one centred around Muslim men (the Hijra) who would abduct women and force them into prostitution. Today some historians have gone so far as to argue that it was this first rape from which Rome got its idea for marriage.
