Excerpt of letter from King of Kongo, Nzinga Mbemba, to Portuguese King João III

“Sir, Your Highness should know how our Kingdom is being lost in so many ways that it is convenient to provide for the necessary remedy, since this is caused by the excessive freedom given by your agents and officials to the men and merchants who are allowed to come to this kingdom to set up shops with goods and many things which have been prohibited by us, and which they spread through our Kingdoms and Domains in such an abundance that many of our vassals, whom we had in obedience, do not comply because they have the things in greater abundance than we ourselves; and it was with these things that we had them content and subjected under our vassalage and jurisdiction, so it is doing a great harm not only to the service of God, but the security and peace of our Kingdoms and State as well. 

And we cannot reckon how great the damage is, since the mentioned merchants are taking every day our natives, sons of the land and the sons of our noblemen and vassals and our relatives, because the thieves and men of bad conscience grab them wishing to have the things and wares of this Kingdom which they are ambitious of, they grab them and get them to be sold; and so great, Sir, is the corruption and licentiousness that our country is being completely depopulated, and Your Highness should not agree with this nor accept it as in your service. And to avoid it we need from those Kingdoms no more than some priests and a few people to reach in schools, and no other goods except wine and flour for the holy sacrament. 

That is why we beg of Your Highness to help and assist us in this matter, commanding your factors that they should nor send here either merchants or wares, because it is our will that in these Kingdoms there should not be any trade of slaves nor outlet for them. Concerning what is referred to above, again we beg of Your Highness to agree with it, since otherwise we cannot remedy such an obvious damage, Pray Our Lord in His mercy to have Your Highness under His guard and let you do forever the things of His service, I kiss your hands many times. 

Many of our people, keenly desirous as they are of the wares and things of your Kingdoms, which are brought here by your people, and in order to satisfy their voracious appetite, seize many of our people, freed and exempt men, and very often it happens that they kidnap even noblemen and the sons of noblemen, and our relatives, and take them to be sold to the white men who are in our Kingdoms; and for this purpose they have concealed them; and others are brought during the night so that they might not be recognized. And as soon as they are taken by the white men they are immediately ironed and branded with fire, and when they are carried to be embarked, if they are caught by our guards’ men the whites allege that they have bought them but they cannot say from whom, so that it is our duty to do justice and to restore to the freemen their freedmen, but it cannot be done if your subjects feel offended, as they claim to be.”
