The problem of the justness of Indian slavery was a key issue for the Casti
lle Crown. It was Charles V who gave a definite answer to this complicated
and delicate matter. To that end he based himself on the arguments given by
the best Spanish theologists and jurists who were unanimous in the condemn
ation of such slavery as unjust; they declared it illegitimate and outlawed
it from America-not just the slavery of Spaniards over Indians, but also t
he type of slavery practised among the Indians themselves.
