“Slаvery, thоugh impоsed аnd mаintained by viоlence, was a negotiated relationship.... First, even as they confronted one another, master and slave had to concede, however grudgingly, a degree of legitimacy to the other.... [T]he web of interconnections between master and slave necessitated a coexistence that fostered cooperation as well as contestation. Second, because the circumstances of such contestation and cooperation continually changed, slavery itself continually changed. . . .
