Which was more important in helping
the Spanish conquistadors defeat the Incas: Spanish
weapons, the Inca civil war, or the smallpox epidemic?
The technology of Spanish crossbows
and horses against Inca spear-throwers and cotton armor,
the five-year civil war in the Inca Empire, and the
devastating effects of the smallpox epidemic all played
a part in the Spanish Conquest of the Incas.
