Long-continued civil wars, arising chiefly from dissensions between rival religious factions, resulting naturally in pestilence and famine, which in the aboriginal annals are attributed to the direct interposition of irate deities, gradually undermine the imperial thrones. Cities and nations previously held in subjection or overshadowed by the splendor and power of Tollan, take advantage of her civil troubles to enlarge their respective domains and to establish independent powers. Distant tribes, more or less barbarous, but strong and warlike, come and establish themselves in desirable localities within the limits of an empire whose rulers are now powerless to repel invasion. So the kings of Tollan, Culhuacan, and Otompan lose, year by year, their prestige, and finally, in the middle of the eleventh century, are completely overthrown, leaving the Mexican table-land to be ruled by new combinations of rising powers. Thus ends the Toltec period of ancient Anáhuac history.
The popular account pictures the whole Toltec population, or such part of it as had been spared by war, pestilence, and famine, as migrating en masse southward, and leaving Anáhuac desolate and unpeopled for nearly a half century, to be settled anew by tribes that crowded in from the north-west when they learned that this fair land had been so strangely abandoned. This account, like all other national migration-narratives pertaining to the Americans, has little foundation in fact or in probability.
The royal families and religious leaders of the Toltecs were doubtless driven into perpetual exile, and were accompanied by such of the nobility as preferred, rather than content themselves with subordinate positions at home, to try their fortunes in new lands, some of which were perhaps included in the southern parts of the empire concerning which so little is known. That there was any essential or immediate change in the population of the table-land beyond the irruption of a few tribes, is highly improbable. The exiled princes and priests, as I have said, went southward, where doubtless they played an important part in the subsequent history of the Maya-Quiché nations of Central America, a history less fully recorded than that of Anáhuac. That these exiles were the founders of the Central American civilization, a popular belief supported by many writers, I cannot but regard as another phase of that tendency above-mentioned to attribute all that is undefined and ill-understood to the great and wonderful Toltecs; nor do I believe that the evidence warrants such an hypothesis. If the pioneer civilizers of the south, the builders of Palenque, Copan, and other cities of the more ancient type, were imbued with or influenced by the Nahua culture, as is not improbable, it certainly was not that culture as carried southward in the eleventh century, but a development or phase of it long preceding that which took the name of Toltec on the Mexican plateaux. With the destruction of the empire the term Toltec, as applied to an existing people, disappeared. This disappearance of the name while the institutions of the nation continued to flourish, may indicate that the designation of the people—or possibly of the ruling family—of Tollan, was not applied contemporaneously to the whole empire, and that in the traditions and records of later times, it has incidentally acquired a fictitious importance. Of the Toltec cities, Culhuacan, on the lake border, recovered under the new political combinations something of her old prominence; the name Culhuas applied to its people appears much more ancient than that of Toltecs, and indeed the Mexican civilization as a whole might perhaps as appropriately be termed Culhua as Nahua.
THE CHICHIMEC EMPIRE.
The new era succeeding the Toltec rule is that of the Chichimec empire, which endured with some variations down to the coming of Cortés. The ordinary version of the early annals has it, that the Chichimecs, a wild tribe living far in the north-west, learning that the fertile regions of Central Mexico had been abandoned by the Toltecs, came down in immense hordes to occupy the land. Numerous other tribes came after them at short intervals, were kindly received and granted lands for settlement, and the more powerful of the new comers, in confederation with the original Chichimec settlers, developed into the so-called empire. Now, although this occupation of the central table-lands by successive migrations of foreign tribes cannot be accepted by the sober historian, and although we must conclude that very many of the so-called new comers were tribes that had occupied the country during the Toltec period,—their names now coming into notice with their increasing importance and power,—yet it is probable that some new tribes, sufficiently powerful to exercise a great if not a controlling influence in building up the new empire, did at this time enter Anáhuac from the immediately bordering regions, and play a prominent part, in conjunction with the rising nations within the valley, in the overthrow of the kings of Tollan. These in-coming nations, by alliance with the original inhabitants, infused fresh life and vigor into the worn-out monarchies, furnishing the strength by which new powers were built up on the ruins of the old, and receiving on the other hand the advantages of the more perfect Nahua culture.
If one, and the most powerful, of these new nations was, as the annals state, called the Chichimec, nothing whatever is known of its race or language. The Chichimecs, their identity, their idiom, and their institutions, if any such there were, their name even, as a national appellation, were merged into those of the Nahua nations that accompanied or followed them, and were there lost. The ease and rapidity with which this tribal fusion of tongue and culture is represented to have been accomplished would indicate at least that the Chichimecs, if a separate tribe, were of the same race and language as the Toltecs; but however this may be, it must be conceded that, while they can not have been the wild cave-dwelling barbarians painted by some of the historians, they did not introduce into Anáhuac any new element of civilization.
NO SUCH NATION AS THE CHICHIMEC.
The name Chichimec at the time of the Spanish conquest, and subsequently, was used with two significations, first, as applied to the line of kings that reigned at Tezcuco, and second, to all the wild hunting tribes, particularly in the broad and little-known regions of the north. Traditionally or historically the name has been applied to nearly every people mentioned in the ancient history of America. This has caused the greatest confusion among writers on the subject, a confusion which I believe can only be cleared up by the supposition that the name Chichimec, like that of Toltec, never was applied as a tribal or national designation proper to any people, while such people were living. It seems probable that among the Nahua peoples that occupied the country from the sixth to the eleventh centuries, a few of the leading powers appropriated to themselves the title Toltecs, which had been at first employed by the inhabitants of Tollan, whose artistic excellence soon rendered it a designation of honor. To the other Nahua peoples, by whom these leading powers were surrounded, whose institutions were identical but whose polish and elegance of manner were deemed by these self-constituted autocrats somewhat inferior, the term Chichimecs, barbarians, etymologically 'dogs,' was applied. After the convulsions that overthrew Tollan and reversed the condition of the Nahua nations, the 'dogs' in their turn assumed an air of superiority and retained their designation Chichimecs as a title of honor and nobility.
The names of the tribes represented as entering Anáhuac after the Chichimecs, but respecting the order of whose coming there is little agreement among authors, are the following: Matlaltzincas, Tepanecs, Acolhuas, Teo-Chichimecs (Tlascaltecs), Malinalcas, Cholultecs, Xochimilcas, Chalcas, Huexotzincas, Cuitlahuacs, Cuicatecs, Mizquicas, Tlahuicas, Cohuixcas, and Aztecs. Some of these, as I have said, may have entered the valley from the immediate north. Which these were I shall not attempt to decide, but they were nearly all of the same race and language, all lived under Nahua institutions, and their descendants were found living on and about the Aztec plateau in the sixteenth century, speaking, with one or two exceptions, the Aztec tongue.
In the new era of prosperity that now dawned on Anáhuac, Culhuacan, where some remnants even of the Toltec nobility remained, under Chichimec auspices regained to a great extent its old position as a centre of culture and power. Among the new nations whose name now first appears in history, the Acolhuas and Tepanecs soon rose to political prominence in the valley. The Acolhuas were the Chichimecs par excellence, or, as tradition has it, the Chichimec nation was absorbed by them, giving up its name, language, and institutions. The capitals which ruled the destinies of Anáhuac down to the fifteenth century, besides Culhuacan, were Tenayocan, Xaltocan, Coatlychan, Tezcuco, and Azcapuzalco. These capitals being governed for the most part by branches of the same royal Chichimec family, the era was one of civil intrigue for the balance of power and for succession to the throne, rather than one of foreign conquest. During the latter part of the period, Tezcuco, the Acolhua capital under the Chichimec kings proper, Azcapuzalco the capital of the Tepanecs, and Culhuacan held the country under their sway, sometimes allied to meet the forces of foreign foes, but oftener plotting against each other, each, by alliance with a second against the third, aiming at universal dominion. At last in this series of political manœuvres Culhuacan was permanently overthrown, and the Chichimec ruler at Tezcuco was driven from his possessions by the warlike chief of the Tepanecs, who thus for a short time was absolute master of Anáhuac.
