Government

Explanation:

John Locke was one of the philosophers who helped develop the idea of social contract during the Enlightenment. The idea of a social contract establishes that there is an implicit contract between the people and the government. The people have agreed to give up some of their freedom in order for the government to exist. In exchange, the government has the duty to act in a way that benefits the people. This theory also states that the sovereignty of the state lies with the people, and not with the government.
