what was the position of the Catholic church in Portugal vis-á- vis slavery?

Question

Howard Zinn "A Peoples History Of The United States" Chapter 2

Answer 1

--Is Catholic--

I do not have the book so I do not know what the exact question is or the time period that you are interested in.

However, I think that if you read about Bartolomé de las Casas that you would find some great help for your question. http://www.newadvent.org/cathen/03397a.htm
