Jared Diamond’s journey of discovery began on the island of Papua New Guinea

On November 15th 1532, 168 Spanish conquistadors arrive in the holy city of Cajamarca, at the heart of the Inca Empire, in Peru. They are exhausted, outnumbered and terrified – ahead of them are camped 80,000 Inca troops and the entourage of the Emperor himself. Yet, within just 24 hours, more than 7,000 Inca warriors lie slaughtered; the Emperor languishes in chains; and the victorious Europeans begin a reign of colonial terror which will sweep through the entire American continent.

So far, Jared Diamond has demonstrated how geography favoured one group of people – Europeans – endowing them with agents of conquest ahead of their rivals around the world.
