In premodern China, Korea, Japan, and Vietnam, just as in the far less
culturally cohesive countries composing the West of the Middle Ages,
enslavement was an assumed condition of servitude warranting little
examination, as the power and profits it afforded to the slaver made it
a convention pursued unreflectively. Slavery in medieval East Asia
shared with the West the commonplace assumption that nearly all humans
were potential chattel, that once they had become owned beings, they
could then be either sold or inherited. Yet, despite being
representative of perhaps the most universalizable human practice of
that age, slavery in medieval East Asia was also endowed with its own
distinctive traits and traditions. Our awareness of these features of
distinction contributes immeasurably to a more nuanced understanding of
slavery as the ubiquitous and openly practiced institution that it once
was and the now illicit and surreptitious one that it intractably
remains.
