A reign is the term used to describe the period of a person's or dynasty's occupation of the office of monarch of a nation (e.g. Canada, Saudi Arabia, Andorra, Tonga) or of a people KwaZulu-Natal, Belgium. In most hereditary monarchies and some elective monarchies (e.g. Holy Roman Empire, Kingdom of Poland) there have been no limits on the duration of a sovereign's reign or incumbency, nor is there a term of office. Thus a reign usually lasts until the monarch dies, unless the monarchy itself is abolished or the monarch abdicates or is deposed.
