The second episode travels to South America and the site of the Spanish conquistadors' near-extermination of the Inca culture in the early 1500s. Brought to life through vivid re-enactments, the episode dramatically depicts conquistador Francisco Pizarro's epic battle with the Inca king Atahualpa. The Inca people quickly proved no match for the conquistadors' formidable arsenal of technologically advanced weaponry and killer germs. The sheer domination of the conquistadors over the Inca served as yet another powerful example of the impact that geography, weapons and disease had in shaping the course of human history.
