I didn't mention Africa, but similar efforts were undertaken there, as well. They did not work forever, though, and many parts of Africa have rejected European influence and are attempting to re-exert their own ways. However, exploitation of raw materials for industrial nations is still a major factor in many parts of Africa. People are still being enslaved and "Christianized."

On the other hand, Islam is gaining headway in many parts of Africa, and is another foreign religion with a goal of dominating entire nations and replacing existing cultures. Christianity and Islam seem to be the most guilty of this of all foreign religions. Both are Abrahamic "religions of the book" Maybe there's something in that to stimulate the greed and conqueror attitudes.
