Monarchy is a system of which a singular ruler governs and oversees the entire nation. The role of a monarch is often passed down from generations to generations.
Theocracy is a system of which a priest or a religious singular governs and oversees an entire body or nation. Often in the name of god.
In several cultures, the monarch is chosen by the god. This can be seen in the Mandate of Heaven in China or the caste system in India; and of course, European states. Religions plays a big role into the population submitting over to the monarch, but monarchy is often passed down from previous predecessors in a family sense. Absolute monarchy is when the monarch have total control of the ruining area and can do whatever he pleases. For theocracy, the priest governs from the point of god. This ruling system is entirely based on religious attributes and the ruler is often chosen as a representative. As the head of the population, the theocrat may speak as god and demand any necessary changes he wishes to bestow upon his ruling area. Theoretically, the theocrat may do whatever he wishes, but he can be opposed by religious skeptics or protests to dethrone the theocrat out of their position.
