Locke argued for the idea that the people are ultimately the source of authority in governing, Thus the people also have the right to unseat a government that is not properly serving the nation's people. John Locke was arguing the idea of a "social contract." According to his view, a government's power to govern comes from the consent of the people themselves -- those who are to be governed. This was a change from the previous ideas of "divine right monarchy" -- that a king ruled because God appointed him to be the ruler. Locke repudiated the views of divine right monarchy in his First Treatise on Civil Government.
