whom they found in possession, a large extent of territory, which as we have seen they were finally forced to yield up to their Zapotec conquerors.
Crossing now to the Atlantic or Gulf shores we have from the past nothing but a confused account of Olmecs, Xicalancas, and Nonohualcas, who may have been distinct peoples, or the same people under different names at different epochs, and who at some time inhabited the lowlands of Tehuantepec and Vera Cruz, as well as those of Tabasco farther south. At the time of the conquest we know that this region was thickly inhabited by a people scarcely less advanced than those of Anáhuac, and dotted with flourishing towns devoted to commerce. But neither in the sixteenth nor immediately preceding centuries can any one civilized nation be definitely named as occupying this Anáhuac Xicalanco. We know, however, that this country north of the Goazacoalco River formed a portion of the Aztec empire, and that its inhabitants spoke for the most part the Aztec tongue. These provinces, known as Cuetlachtlan and Goazacoalco, were conquered, chiefly with a view to the extension of the Aztec commerce, as early as the middle of the fifteenth century, notwithstanding the assistance rendered by the armies of Tlascala.
THE TLASCALTECS.
The plateau east of Anáhuac sometimes known as Huitzilapan was found by the Spaniards in the possession of the independent republics, or cities, of Tlascala, Huexotzinco, and Cholula. The people who occupied this part of the table-land were the Teo-Chichimecs, of the same language and of the same traditional north-western origin as the Aztecs, whom they preceded in Anáhuac. Late in the thirteenth century they left the valley of Mexico, and in several detachments established themselves on the eastern plateau, where they successfully maintained their independence of all foreign powers. As allies of the Chichimec king of Tezcuco they aided in overturning the Tepanec tyrant of Azcapuzalco; but after the subsequent dangerous
