Answer:
A monarch.
Step-by-step explanation:
A monarchy is originally a form of government in which power rests with one person, the monarch. Monarchies are divided into absolute monarchies and constitutional monarchies. In an absolute monarchy, the monarch's power is "absolute", that is, he has unlimited ruling power. Today there are seven absolute monarchies: Brunei, Oman, Saudi Arabia, Swaziland, Vatican City, United Arab Emirates and Qatar. In a constitutional monarchy, the role of the monarch is defined in the constitution, which generally means that legislative power rests with parliament and the monarch only has executive power. Sometimes the monarch still has an important role, in other cases, for example in Sweden, he has only a ceremonial role.
