Itzcoatl, with the greatest skill, calmed their agitation, and summoned them to another combat, which should decide the fate of the still youthful monarchy of the Mexicans. A great battle was fought against the Tepanecs with Maxtla at their head. Opposite him were arranged the united forces of the Mexicans, the Chichimecs, and their allies, of the neighboring little state of Tlatelolco, as well as a great body of auxiliary troops, which ranged themselves on the side of justice and against the terrible tyrant. The allied army sallied forth to the encounter, but was driven back, and the city of Tenochtitlan was about to fall into the hands of Maxtla, when the three chiefs, Nezahualcoyotl, Itzcoatl and Motecuhzoma, followed by their bravest warriors, plunged into the thickest of the fray, and by the fury of their attack caused the Tepanecs to flee with all haste. The battle was continued the next day, victory declaring itself for the allies, who pursued the Tepanecs even into their own capital Atzcapotzalco, where they set fire to the houses, sacking them first, and killing the inhabitants. The king Maxtla himself fell under the stroke of Nezahualcoyotl, who thus avenged the murder of his father. The taking of the capital city was the end of the kingdom of the Tepanecs. This took place in 1428. By the downfall of this monarchy, Nezahualcoyotl was reinstated upon the throne of his ancestors, at Texcuco, henceforth called the kingdom of Acolhuacan; a small new kingdom arose, upon the ruins of the old, called that of the Tepanecs of Tlacopan; these two formed with the Mexicans a triple alliance which lasted for more than a century. This alliance is called that of the "Valley Confederates," who by their united strength could crush the surrounding isolated tribes with perfect success. Itzcoatl died in 1440, much lamented by his people. His obsequies were performed with great solemnity. He was justly celebrated for his great gifts, and the services he rendered his country. An old author says of him that he was "a man so excellent that there is no language sufficient for his praises." On the death of this ruler, the Mexicans again came together to choose a king, and unanimously selected Motecuhzoma Ilhuicamina, brother of the late king, and son of the first one. His election was received with enthusiasm, because he was a great general, who had filled the minds of the people with his brilliant deeds in emancipating them from the tyrant control of the Tepanecs. Under this king the fortunes of the Mexicans reached their height. He was a great warrior, and by force of arms he subdued many surrounding tribes, and extended the power of his kingdom. He was an intense fanatic in religion, and a true despot, and carried his convictions to an extreme which, while it extended his power, alienated the other peoples of Anahuac, so that in the dark days of the future, they were ready rather to be against the Mexicans than for them.
