greater part of Central America, with one striking exception, the Zapotec, and as such must belong to an earlier movement of tribes than the actual Aztec migration from Aztlan. The Nahua-speaking tribes, including the Toltec, and the Michoacans, called themselves Chichimec, a term which, as mentioned above, possesses rather a cultural than a racial significance, and means wandering hunters. In fact the Aztec are shown in manuscripts as skin-clad archers on their migration, fighting with the inhabitants of the valley, who are represented as dressed in textiles and armed with the macquauitl, or wooden sword edged with obsidian. The first inroad of Chichimec after the destruction of Tulan (though no doubt that destruction was caused, at any rate in part, by the pressure of nomadic tribes from the north), is said to have taken place under the leadership of a chief called Xolotl, coming from a country named Amaquemacan via Chicomoztoc and Tulan. Xolotl established his court at Tenayocan, and proceeded to extend his power over the other cities round the lake, incorporating such of the Toltec as remained in his empire.

These chiefs allied themselves with Xolotl, and the first two were given his two daughters in marriage, receiving at the same time the towns of Azcapotzalco and Xaltocan respectively as residences.

Colhuacan at this time was ruled by Pochotl, a descendant of the last Toltec king, and Xolotl seems to have exercised a loose suzerainty over all. The invaders rapidly adopted the remains of civilization which they found in the valley,and applied themselves to agriculture; the old name of Chichimec was dropped, and
