Answer:
A Social contract
Step-by-step explanation:
Social contract in political philosophy is a contract between the rulers and the subjects that defines the duties and rights of each. According to this theory, humans were born in an anarchic state of nature and later formed a society by means of a contract among themselves. This contacts can be trace back to Greek Sophists and is associated with philosophers Thomas Hobbes, John Locke and Jean Jacques Rousseau.
According to Hobbes in the state of nature there was no criteria of right and wrong and people could do whatever they wanted and the state of nature was a state of war. This state ended when the individuals agreed to surrender their freedom to a absolute sovereign and he safeguarded their lives with his sovereignty.
