Monarchy was the most common form of government into the 19th century, but it is no longer prevalent, at least at the national level. Currently, 44 sovereign nations in the world have monarchs acting as heads of state, 16 of which are Commonwealth realms that recognize Queen Elizabeth II as their head of state. All European monarchies are constitutional ones, with the exception of the Vatican City, but sovereigns in the smaller states exercise greater political influence than in the larger. The monarchs of Cambodia, Japan, Jordan, Malaysia and Morocco "reign, but do not rule" although there is considerable variation in the amount of authority they wield. Although they reign under constitutions, the monarchs of Brunei, Oman, Qatar, Saudi Arabia and Swaziland appear to continue to exercise more political influence than any other single source of authority in their nations, either by constitutional mandate or by tradition.
