NAHUATLACA MIGRATION.

The original home of the Nahuatlacas was Aztlan, the location of which has been the subject of much discussion.[V-39] The causes that led to their exodus from that country can only be conjectured;[V-40] but they may be supposed, however, to have been driven out by their enemies, for Aztlan is described as a land too fair and bounteous to be left willingly in the mere hope of finding a better.[V-41] The native tradition relates that a bird was heard for several days constantly repeating the word tihui, tihui, meaning 'let us go,' 'let us go.' This, Huitziton, foremost and wisest among the Nahuatlaca chiefs, took to be a message from the gods directing the people to seek a new home. In making a declaration of such moment he needed the support of another influential man. He accordingly persuaded another chief called Tecpatzin, who at first seemed sceptical, that the bird's note was nothing less than a divine message, and the two announced it as such to the people.[V-42]

Whether all the numerous tribes into which the Nahuatlacas were divided, left Aztlan at the same time, or, if not, in what order they left, it is impossible to tell. It seems, however, that after several years' wandering, a number of them were together at a place called Chicomoztoc, the famous 'seven caves.'[V-43] The little that is known of their wanderings before reaching this point will be found in the next chapter, in connection with the Aztec migration.

The list of tribes settled at Chicomoztoc at this time comprises only seven according to most authors. They are named for the most part after the locality in which they subsequently settled in and about Anáhuac, and are as follows: the Xochimilcas, Chalcas, Tepanecs, Acolhuas, Tlahuicas, Tlascaltecs, and Aztecs or Mexicans; to which some writers add the Tarascos, Matlaltzincas, Malinalcas, Cholultecs, Huexotzincas, Cuitlahuacs, Mizquicas, and Cohuixcas.[V-44] Some authors do not include the Acolhuas and Tepanecs; no importance is, however, to be attached to the traditional tribal divisions of the invading hordes before they settled in Anáhuac.

It was at Chicomoztoc that the separation of the Aztecs from the rest of the Nahuatlacas took place. The tradition relates that while the people were seated beneath a great tree partaking of a meal, a terrible noise was suddenly heard to issue from the summit of the tree; the idol which stood upon the altar at its foot then called the chiefs of the Aztec tribe aside and commanded them to order the other tribes to depart in advance, leaving the Aztecs at Chicomoztoc. The number of tribes that were thus sent in advance is not known; Torquemada says eight, Acosta and Duran say six,[V-45] and others greater or smaller numbers.

ACOLHUAS AND TEPANECS.

From the time of the separation we hear little more of the Nahuatlaca tribes until we find them coming into Anáhuac and settling in various parts of the country. In this manner we hear of the Xochimilcas, 'cultivators of flowers,' coming into the valley and occupying a district south of Tezcuco Lake, where they founded Xochimilco; but all we know of their former history is that they left Aquilazco, their original home, which we may suppose to have been a district of Aztlan, under a chief named Huetzalin,[V-46] who, dying on the journey, was succeeded by Acatonal, who conducted the tribe as far as the ruined city of Tollan and there died, after having ruled twenty-three years. The tribe then proceeded under the conduct of Tlahuil Tecuhtli[V-47] to the Culhuacan territory and attempted to settle there, one year after the accession of Huetzin.[V-48] But the people of Culhuacan were suspicious of the new comers and drove them to the other side of the lake to a place called Teyahualco, at the same time forbidding them to settle on any part of the lands belonging to the capital. For some years the Xochimilcas remained quietly at Teyahualco, but in 1141 Tlahuil Tecuhtli pounced suddenly upon Culhuacan, and before its defenders could gain their arms he penetrated into the heart of the city and sacked it remorselessly. The inhabitants soon rallied, however, and not only drove the marauders out of the city, but pursued them as far as the site of the ancient city of Ocopetlayuca. Here Tlahuil Tecuhtli resolved to establish himself and, with the permission of the king of Culhuacan, he forthwith founded the city of Xochimilco, which subsequently became one of the principal places in Anáhuac.[V-49] The Chalcas settled on the east side of the lake of Chalco and founded a number of towns of which the principal was Chalco. For the Tlahuicas no room could be found about the lake; they therefore proceeded to a district south of Mexico, where before long a number of settlements rose around their capital Quauhnahuac.[V-50] Of the other tribes included by some authors among the Nahuatlacas, we find the Tarascos settled in Michoacan, the Matlaltzincas in the province of that name, and extending towards Michoacan; the Malinalcas in the province of Malinalco; the Cuitlahuacs in the province of Cuitlahuac; the Mizquicas in Mizquic; the Cohuixcas in Guerrero.[V-51]

ACOLHUAS AND TEPANECS.

The Tepanecs and Acolhuas become prominent in the affairs of Anáhuac at this period, that is, during the reign of the Chichimec emperor Xolotl II. They were among the numerous bands that contributed to the overthrow of the Toltec empire, and are classed by several writers among the Nahuatlaca tribes.[V-52] One of their chiefs, Tzontecoma of Coatlichan, was, as we have seen, the grandfather of Huetzin, the present king of Culhuacan. The event that brings them into prominent notice at this time is their tendering allegiance to Xolotl II. In doing this they claimed descent from the Citin,[V-53] illustrious for nobility of race and for heroic deeds. According to many of the Spanish writers the Otomís came into Anáhuac and tendered their allegiance to Xolotl II. in company with the Acolhuas and Tepanecs. We have already seen, however, that the Otomís were one of the most ancient nations of Anáhuac, and were there long before the Toltecs; this reputed entry of theirs was perhaps nothing more than their coming in from the mountains and adopting, to a certain extent, a civilized life.[V-54] The story goes that Xolotl II. and his son Nopaltzin were flattered by the propositions of these powerful chiefs and entertained their guests right royally. Nor did the Chichimec monarch delay to confer upon the three principal chiefs substantial marks of his favor and consideration. To the lord Acolhua with the Tepanecs he assigned several districts south of Tenayocan, with Azcapuzalco for a capital, and gave him the hand of his eldest daughter, Cuetlaxochitl, in marriage; the lord of the Otomís received the emperor's second daughter, and a district four or five leagues north of Azcapuzalco, with Xaltocan for its capital; Tzontecoma, the third chief, a young man, was awarded for the Acolhua home a district one league south of Tezcuco, with Coatlichan for a capital, and, as Xolotl had no more daughters, he was given for a wife the princess next in rank.[V-55] It was in compensation for this inferior marriage that Xolotl afterwards obtained the throne of Culhuacan for Tzontecoma's grandson, Huetzin, according to Torquemada's account given on a preceding page. The three marriages were celebrated at Tenayocan with extraordinary pomp, and were followed by a succession of public games, gladiatorial exhibitions, and amusements of all sorts, which lasted sixty days.

It is difficult to say in what relation the Acolhua and Tepanec princes stood towards the Chichimec emperor. According to most of the Spanish authorities, they swore allegiance to Xolotl, and took rank as the first vassals of the empire, though they were exempted from payment of tribute. It is Brasseur's opinion, however, that this statement must not be accepted too literally. Nothing was more jealously guarded by all these peoples than their independence and sovereign rights in the land they occupied. At the same time, the right of first occupation being held sacred by them, it was natural that the tribes that came in after the Chichimecs, should address themselves to Xolotl, before attempting any formal settlement. The act of the new tribes was, therefore, an observance of international etiquette rather than an acknowledgment of vassalage.[V-56]
