The term 'MONARCH's Rule' refers to the REIGN of a MONARCH, which is a person who holds the highest position in a monarchy. A monarchy is a form of government in which a single individual, usually a king or queen, holds supreme authority over a state. The MONARCH's rule is typically absolute and hereditary, meaning that it is passed down from one generation to the next. The MONARCH's power is usually limited by law and tradition, and they are often subject to the will of the people.
