Answer:
Social Contract.
Step-by-step explanation:
According to LockeĀ“s conception of the state, all humans are bounded to naturally form a state. This state is given the legitimacy by all the citizens to rule and protect their rights, freedom and property. This conception of the state is based on the Natural Law, which, according to Locke, eventually leads all human to bestow their prerogatives in exchange for protection and to keep the social order.
This conception of the Social Contract along with the work of Thomas Hobbes, influenced the ideas of Jean Jacques Rousseau and henceforth, the pillars of modern Liberalism.
