The desolation of Anáhuac as the Toltecs fell invited a foreign occupation, and a remote people called Chichimecs[833]—not to be confounded with the primitive barbarians which are often so called—poured down upon the country. Just how long after the Toltec downfall this happened, is in dispute;[834] but within a few years evidently, perhaps within not many months, came the rush of millions, if we may believe the big stories of the migration. They surged by the ruined capital of the Toltecs, came to the lake, founded Xoloc and Tenayocan, and encountered, as they spread over the country, what were left of the Toltecs, who secured peace by becoming vassals. Not quite so humble were the Colhuas of Colhuacan,—not to be confounded with the Acolhuas,—who were the most powerful section of the Toltecs yet left, and the Chichimecs set about crushing them, and succeeded in making them also vassals.[835] The Chichimec monarchs, if that term does not misrepresent them, soon formed alliances with the Tepanecs, the Otomis, and the Acolhuas, who had been prominent in the overthrow of the Toltecs, and all the invaders profited by the higher organizations and arts which these tribes had preserved and now imparted. The Chichimecs also sought to increase the stability of their power by marriages with the noble Toltecs still remaining. But all was not peace. There were rebellions from time to time to be put down; and a new people, whose future they did not then apprehend, had come in among them and settled at Chapultepec. These were the Aztecs, or Mexicans, a part of the great Nahua immigration, but as a tribe they had dallied behind the others on the way, but were now come, and the last to come.[836] Tezcuco soon grew into prominence as a vassal power,[837] and upon the capital city many embellishments were bestowed, so that the great lord of the Chichimecs preferred it to his own Tenayocan, which gave opportunity for rebellious plots to be formed in his proper capital; and here at Tezcuco the next succeeding ruler preferred to reign, and here he became isolated by the uprising of rebellious nobles. The ensuing war was not simply of side against side, but counter-revolutions led to a confusion of tumults, and petty chieftains set themselves up against others here and there. The result was that Quinantzin, who had lost the general headship of the country, recovered it, and finally consolidated his power to a degree surpassing all his predecessors.
