It seems the greatest skill of the Europeans was erasure of other culture and peoples , whilst at the same time claiming their knowledge as their own. May I suggest you include a couple of references for the facts you state, so others can turn to more in depth sources of alternative history than the colonising one? I have decided to start doing that - eg in my latest article on the British monarchy. This helps give visibility to silenced voices such as that of the great Walter Rodney, who was assassinated at such a young age... He is the author of 'How Europe Underdeveloped Africa'.
