popular sovereignty means that the power of a government comes from the consent of whom
Popular sovereignty Popular sovereignty, or sovereignty of the peoples' rule, is the principle that the authority of a state and its government is created and sustained by the consent of its people, through their elected representatives (Rule by the People), who are the source of all political power. It is closely associated with social contract philosophers such as Thomas Hobbes, John Locke and Jean-Jacques Rousseau. Popular sovereignty expresses a concept and does not necessarily reflect or describe a political reality.[a] The people have the final say in government decisions. Benjamin Franklin expressed the concept when he wrote, "In free governments, the rulers are the servants and the people their superiors and sovereigns".[1]
Republic A republic (Latin: res publica) is a form of government in which the country is considered a "public matter", not the private concern or property of the rulers. The primary positions of power within a republic are not inherited, but are attained through elections expressing the consent of the governed. Such leadership positions are therefore expected to fairly represent the citizen body. It is a form of government under which the head of state is not a monarch.[1][2][3] In American English, the definition of a republic can also refer specifically to a government in which elected individuals represent the citizen body, known elsewhere as a representative democracy (a democratic republic)[4] and exercise power according to the rule of law (a constitutional republic).[5][6][2]
