Theory of Divine Right: This theory claims that God created the state, and He gave the right to govern to some specific people. Ex. European monarchies in the Middle Ages.
Evolutionary Theory: Argues that the state develop from primitive families. As the families grew, the organizations turned into clans, and then into tribes. Ex. some Native American clans.
Force Theory: One individual or a group of individual exert force over another group, imposing their rule. Ex. wars of conquest.
Social Contract: It argues that the community has a contract with the government, in which they will give uo some of their liberties in exchange for protection or the preservation of the common good. Ex. Rousseau’s political philosophy.
The two theories that best predict the rise of a dictator are Force Theory and the Theory of Divine Right.
