The early history of these tribes is very difficult to elucidate from the tangled mass of migration myths, often contradictory, which have survived. What may be termed the historical period starts only with the election of the first Aztec king, some years after the settlement of the tribe at Tenochtitlan, and this takes us back only to about 1376, or not much more than a century before the Spanish conquest. The Aztec, when they arrived, found a number of Nahua-speaking “Chichimec” in occupation of the valley, and these “Chichimec” had themselves found the remains of a culture far above their own, to which they gave the name of Toltec. Now the “Toltec question” has been hotly debated from early times; to the Mexicans the Toltec were the people of a golden age, and their state was the prototype of peaceful civilization. Some writers have gone so far as to deny them actual existence at all, regarding them as a purely mythical people to whom the Mexicans conveniently attributed the invention of all useful arts of which they could not readily explain the evolution otherwise. Others have exalted their culture to a pitch far above, one might almost say, the human, and have credited them with a knowledge transcending that of latter-day civilization. I do not propose to plunge into the welter of controversial theories, but to regard the matter from a strictly practical point of view, which seems to me to be as follows. The Aztec and their immediate fore-runners the “Chichimec” were merely nomadic hunters when they settled in the valley, and their knowledge of arts and crafts, which need a settled life for development, had not advanced beyond a very primitive stage. They found the remains of a people who had for years been living as settled agriculturists, and ruined cities which their untutored minds regarded as something bordering on the marvellous. The agricultural population whom they subdued, more cultured but less warlike than they, told them stories of a powerful empire, stories which no doubt lost nothing in the telling. To this empire they gave the name of Toltec, from the city of Tulan (or Tollan) which was its reputed centre. Modern research has proved conclusively the existence, at those very localities especially associated with the Toltec, of pre-Aztec ruins, and of a relatively high culture which prevailed throughout the valley (and beyond) for a period considerably longer than that which elapsed between the Aztec immigration and the Spanish conquest. As a mere matter of evidence I cannot see that any name can be given to this pre-Aztec culture other than that of Toltec, and, further, that it is possible to deny at least a foundation in fact to the myths connected with this people. However, even so, the difficulties connected with the question are not entirely solved; Sahagun states definitely that the Toltec spoke Nahua, and relates a migration myth which brings them into contact with the Nahua peoples before their settlement in Tulan.
