Elected monarch

An elective monarchy is a monarchy ruled by an elected monarch, 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 is not uncommon for elective monarchies to transform into hereditary ones over time, or for hereditary ones to acquire at least occasional elective aspects.

Many, if not most, kingdoms were officially elective historically, though the candidates were typically only from the family of the deceased monarch. Eventually, however, most elected monarchies introduced hereditary succession, guaranteeing that the title and office stayed within the royal family and specifying, more or less precisely, the order of succession.

Today, almost all monarchies are hereditary monarchies in which the monarchs come from one royal family with the office of sovereign being passed from one family member to another upon the death or abdication of the incumbent.

The kings of Macedon and of Epirus were elected by the army, which was similar in composition to the ecclesia of democracies, the council of all free citizens. Military service often was linked with citizenship among the male members of the royal house.

In the ancient Kingdom of Rome, the kings were elected by the Assemblies. Once the Roman kings were overthrown, there remained an absolute prohibition for royal establishment in the Roman constitution, a prohibition which formally remained in place during imperial times, both Roman and Byzantine, although in practice the empire was an absolute monarchy. Therefore, the office of Roman and Byzantine emperor remained vaguely elective (albeit with the election procedure never strictly defined, but generally understood to be a matter for the Senate) and heredity never was, and could never be, formally established in law. In order to bypass this prohibition and ensure dynastic continuity, many reigning Byzantine emperors had their heirs crowned co-emperor so that the throne could not be considered vacant at their own death and thus the need for succession by election would not arise.
