A monarchy is a form of government in which a group, usually a family called the royalty, embodies the country’s national identity and one of its members, called the monarch, exercises a role of sovereignty.

The word “monarch” (Latin: monarcha) comes from the Greek language word μονάρχης, monárkhēs (from μόνος monos, “one, singular”, and ἄρχω árkhō, “to rule” (compare ἄρχων arkhon, “leader, ruler, chief”)) which referred to a single, at least nominally absolute ruler. In current usage the word monarchy usually refers to a traditional system of hereditary rule, as elective monarchies are rare nowadays.

Through a monarchy leaders known as monarch were put into place, some of the monarchs derived their status from the royal lineage of the kings throne, and their governance stretched as far as the colonies that they colonised.

A Monarchy ruled and governed their colonised colonies through their colonial masters, after granting independence to the people they colonised, then a president was put in place (office of executive) to replace the colonial master.

The monarch of England uses the system of commonwealth to design constitutions which governs their colonised colony.

For example, the monarch and the president are recognized as their respective heads of state, while the prime-minister and the chancellor are recognized as the heads of government.

Monarchy and it’s vision is that which lines up with the mandate of heaven (all authority is authorised and mandated from heaven, and on earth human beings are given power to exercise it).

A Monarchy is mandated from heaven: 

According to this belief, heaven bestows its mandate to a just ruler, the son of heaven. The Mandate of Heaven depends on whether an emperor is sufficiently virtuous to rule; if he does not fulfill his obligations as emperor, then he loses the Mandate and thus the right to be emperor. 

The Mandate of Heaven would then transfer to those who would rule best. The fact that a ruler was overthrown was taken by itself as an indication that the ruler had lost the Mandate of Heaven. In addition, it was also common belief that natural disasters such as famine and flood were other signs of heaven’s displeasure with the current ruler, so there would often be revolts following major environmental events as citizens saw these as signs of heaven’s displeasure.
