“Hostis humani generis” is a Latin phrase that means “enemy of all mankind” in English. This phrase is often used in legal and international contexts to refer to individuals or entities that have committed acts which are so heinous and universally condemned that they are seen as enemies of humanity as a whole. This term is often associated with piracy, war criminals, and individuals or organizations involved in acts of terrorism or genocide. Such entities are considered threats not just to specific nations or groups, but to all of humanity.
