In practice, however, Imperial Rome was a monarchy. 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 classical Roman and Byzantine. In the ancient Roman Kingdom the kings were elected by the Roman assemblies. Military service often was linked with citizenship among the male members of the royal house. The kings of Macedon and of Epirus were elected by the army, which was similar in composition to the Ecclesia of the Demos, the assembly of all free Athenian citizens. Historical examples Europe Ancient Greece 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. 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. Many, if not most, kingdoms were officially elective historically, though the candidates were typically only from the family of the deceased monarch. 2.1.12 Sovereign Military Order of Malta.2.1.10 Poland (Polish-Lithuanian Commonwealth).
