How is it possible that in 1521 five-hundred Spanish soldiers defeated the most powerful military force in Middle America? The answer lies not in western firearms, as we have been taught, but rather in the differences between the Aztec and Spanish cultures. Differing concepts of warfare and diplomacy, reinforced by tensions and stresses within the Aztec political system and its supporting religious beliefs, allowed Cortés to systematically gain and hold the military and diplomatic advantages that gave the Spaniards the day, the war, and the continent.
