Elective monarchy

Monarchy ruled by an elected ruler

An elective monarchy is a monarchy ruled by a monarch who is elected, in contrast to a hereditary monarchy in which the office is automatically passed down as a family inheritance. The manner of election, the nature of candidate qualifications, and the electors vary from case to case. Historically, it was common for elective monarchies to transform into hereditary ones by repeated election of the previous rulers' children, or for hereditary monarchies to acquire elective or semi-elective succession laws, particularly following dynastic crises.
