a monarchy is a form of government in which one person has the hereditary right to rule as head of state during his or her lifetime. this means that the nation's leader is born into this position. the queen of england is an example of a monarch. the president of the united states is not a monarch, though sometimes people refer to a president's family as american royalty.
in an absolute monarchy, the monarch has unlimited power due to his or her position. at times, monarchs have been thought to rule by the grace of god, believing that god granted them the power to rule. this idea is known as ruling by divine right.
today, many monarchies are constitutional monarchies. this means the monarch shares power with other branches of government. in a constitutional monarchy, for example, the monarch is only the head of state rather than being the head of government. for example, in england, the monarch shares power with the parliament. a constitutional monarchy is usually also a parliamentary democracy. the united kingdom is an example of a constitutional monarchy.
