I've got a copy of The Conquest of Mexico by Hugh Thomas on my book shelf and I tell myself I will eventually finish reading the tome!
This article might help me reinspire myself with this history.
I sometimes like to wonder what if, and wonder how vastly different world history could have been. If the Catholic conquistadors had managed to overcome superstition and fear of the devil to try Teonanácatl, Peyotl, Cohoba and Ayahuasca.
