“Conquest is not the victory itself; but the acquisition, by victory, of a right over the persons of men. He therefore that is slain is overcome, but not conquered: he that is taken and put into prison or chains is not conquered, though overcome; for he is still an enemy, and may save himself if he can: but he that upon promise of obedience hath his life and liberty allowed him, is then conquered and a subject; and not before.”

-- Thomas Hobbes, Leviathan
