Answer 2

In political philosophy, the phrase consent of the governed refers to the idea that a government's legitimacy and moral right to use state power is only justified and legal when consented to by the people or society over which that political power is exercised. This theory of consent is historically contrasted to the divine right of kings and has often been invoked against the legitimacy of colonialism. Article 21 of the United Nation's 1948 Universal Declaration of Human Rights states that "The will of the people shall be the basis of the authority of government".
