By the time the Spanish arrived, the Aztec Empire wasn’t “Tribes” but a highly organized militaristic brutal despotic state that controlled the lives of perhaps 15 million people — more than that of Spain. By comparison, the contemporary population of France, the largest country in Europe at the time, was around 20 million. Among the more notorious actions of the Aztecs were the burning of all historical records, human sacrifice, and cannibalism.
