development of Aztec ambition, the Tlascaltec armies aided in nearly every attempt of other nations to arrest the progress of the Mexicans toward universal dominion. Their assistance, as we have seen, was unavailing except in the final successful alliance with the forces of Cortés; for, although secure in their small domain against foreign invasion, their armies were often defeated abroad. Tlascala has retained very nearly its original bounds, and the details of its history from the foundation of the city are, by the writings of the native historian Camargo, more fully known than those of most other nations outside of Anáhuac. This author, however, gives us the annals of his own and the surrounding peoples from a Tlascaltec stand-point only. Before the Teo-Chichimec invasion of Huitzilapan, Cholula had already acquired great prominence as a Toltec city, and as the residence of the great Nahua apostle Quetzalcoatl, of which era, or a preceding one, the famous pyramid remains as a memento. Outside of Cholula, however, the ancient history of this region presents but a blank page, or one vaguely filled with tales of giants, its first reputed inhabitants, and of the mysterious Olmecs, from some remaining fragments of which people the Tlascaltecs are said to have won their new homes. These Olmecs seem to have been a very ancient people who occupied the whole eastern region, bordering on or mixed with the Xicalancas in the south; or rather the name Olmec seems to have been the designation of a phase or era of the Nahua civilization preceding that known as the Toltec. It is impossible to determine accurately whether the Xicalancas should be classed with the Nahua or Maya element, although probably with the former.
The coast region east of Tlascala, comprising the northern half of the state of Vera Cruz, was the home of the Totonacs, whose capital was the famous Cempoala, and who were conquered by the Aztecs at the close of the fifteenth century. They were probably
one of the ancient pre-Toltec peoples like the Otomís and Olmecs, and they claimed to have occupied in former times Anáhuac and the adjoining territory, where they erected the pyramids of the sun and moon at Teotihuacan. Their institutions when first observed by Europeans seem to have been essentially Nahua, and the abundant architectural remains found in Totonac territory, as at Papantla, Misantla, and Tusapan, show no well-defined differences from Aztec constructions proper. Whether this Nahua
