School of Salamanca
A parallel development of a theory of popular sovereignty can be found among the School of Salamanca (see e.g. Francisco de Vitoria (1483–1546) or Francisco Suarez (1548–1617)), who (like the theorists of the divine right of kings and Locke) saw sovereignty as emanating originally from God, but (unlike divine right theorists, and in agreement with Locke) passing from God to all people equally, not only to monarchs.
