The Aztecs were few in numbers when they first came to the shores of the lake, but they increased rapidly in population and in power. Nearby were other Indian tribes, and, as there was much warfare between them, the Aztecs united themselves with the King of the Tezcucans in order to aid him against a tribe called the Tepanics, who had invaded his territory. The allies won, and, as a result, an agreement was made between the states of Mexico, Tezcuco, and Tlacopan, that they should support one another in the wars and divide all the spoils between them. This alliance remained unbroken for over a hundred years. Although fond of warfare and cruel in their tortures to prisoners, the Aztecs had many wise laws and institutions, and were, in some respects, highly civilized. They were governed by an Emperor, and, when he died, another one was chosen by four nobles from among his sons or nephews. The one preferred was obliged to have distinguished himself in war, and he was not crowned until he had waged a successful campaign, had captured large numbers of the enemy, and thus provided enough captives to grace his entry into the capital. The Aztecs worshiped thirteen principal gods, and more than two hundred of less importance, whose temples were everywhere to be seen. At the head of all the gods was the great Huitzilopochtli, whose temples were in every city of the empire, and whose image was always loaded with costly ornaments. They also had a legend that there had once dwelt upon the earth the great god, Quetzalcoatl, god of the air, under whose sway the Aztec people had flourished and there had been peace and prosperity among all men. He was said to have been tall in stature, with a white skin, long, dark hair, and a flowing beard. He had, in fact, quite resembled a Spaniard, and this led to the success which Cortés had with the Mexicans, as you will presently see. Quetzalcoatl, it was said, had in some way incurred the wrath of the principal gods, so that he had been forced to leave the country. He had turned towards the Gulf of Mexico, had stopped at the city of Cholula, and had then departed in a magic boat, made of serpent’s skins, to the fabled land of Tlapallan. Tradition had it that as he was leaving, he had turned to the faithful ones who had followed him saying: “Watch and wait for me, I shall come again.” For this reason the Aztecs were ever on the lookout for the great and benevolent god of the white skin and flowing beard.
