Even despite his involvement in enslavement of the natives

When and where did that happen?

[Verginius Rufus]

If I remember correctly, Columbus took back a few natives from Hispaniola on his first voyage to be able to show he had really reached a new land, but then on the second voyage captured hundreds of natives to be slaves, but Queen Isabella freed them. Unfortunately some of them had already died.
