Describing the horrors and ravages of the slave-trade, he declared that the provinces of Guatemala and Nicaragua had been depopulated, while in the provinces of Jalisco, Yucatan, and Panuco, similar outrages had been perpetrated, adding that the Germans in Venezuela were even more adroit than the Spaniards in the nefarious art of raiding Indian villages to carry off the inhabitants into slavery. “Your Majesty will see that I do not exaggerate when I affirm that more than four million men have been reduced to slavery, all of which has been accomplished in defiance of your Majesty’s royal instructions.” Throughout this treatise, Las Casas supports his contentions on citations from Scripture, and in the second article, dealing with the obligations of the King towards his Indian subjects, he defines in very plain language the sanctions on which the royal claims to obedience rest: “The law of God imposes on the king the obligation to administer his kingdoms in such wise that small and great, poor and rich, the weak and the powerful, shall all be treated with equal justice”;—such is his Statement of the King’s duty and he supports it with quotations from Deuteronomy, Leviticus, the prophet Isaias, and St. Jerome, concluding with these words: “In fact, history furnishes examples of God chastising the nations and kingdoms which have refused justice to the poor and the orphan. Who shall venture to say that such may not be the fate of Spain, if the King denies the poor Indians their just dues and fails to give them the liberty, to which they have an incontestable right?” Nor does he limit the King’s responsibility to his personal acts in cases which may come directly to his knowledge; he is obliged also to see that his subjects observe one another’s rights and live according to the laws of civil order and public morality. The object for which society and rulers exist is to insure the common weal of all, and no sovereign can secure this, who does not base his government on the principles of virtue and justice. The Spanish king is therefore not only obliged to secure the liberty of the Indians because justice exacts this of him, but also because he is bound to prevent his Spanish subjects from acts of usurpation of the rights of others. Christian kings have greater duties than those which weigh upon heathen or heretical rulers, for they are bound to protect religion, favour its ministers, and spread the faith for the sanctification of the whole world. By securing liberty to the Indians, their conversion would be assured and, all causes of enmity and hatred against Spaniards being removed, the natives would eagerly welcome the missionaries and receive their teaching.
