I call 'government' or supreme administration the legitimate exercise of executive power; I call 'prince' or magistrate the man or body charged with that administration.
Gist of Idea
I call the executive power the 'government', which is the 'prince' - a single person, or a group
Jean-Jacques Rousseau (The Social Contract (tr Cress) , III.01)
Whether the prince is one person or many is left up to the legislative body, which is the general will. Rousseau has no view on the matter.
