Actually, it was the Portuguese who were the great sinners with regard to slavery. They found it in existence in Africa and Asia, but made it a lot worse by applying Roman law on slavery to that status.
The Spanish did likewise in the Americas, and when the Dutch and the British supplanted the Portuguese from many of their African and Oriental possessions, they took over the existing slave system.

The experience of the Canadian First Nations in boarding schools was much the same as that of the Australian Aborigines in the first half of the 20th century.
And even here in South Africa there has been a blending of cultures – with some extraordinary outcomes.
