In 1457, he sent an expedition against the Cotastese, and took 6,200 prisoners, whom he sacrificed to his god. He also took signal vengeance again on the Chalchese, who had rebelled, and had sought to make one of his brothers king in his stead. The brother pretended to comply; but mounting a scaffold which he ordered to be erected, and taking a bunch of flowers in his hand, then urging his attendant Mexicans to be faithful to their king, he threw himself from the scaffold. This enraged the Chalchese so much that they put the Mexicans to death, for which Montezuma made war against them till he had almost exterminated them. He finally, however, proclaimed a general amnesty. He constructed a dike, nine miles long and eleven cubits broad, to prevent the recurrence of an inundation which had happened, and which was followed by a famine. He died in 1464. Montezuma the First was succeeded by Axayacatl, who pursued the conquests so successfully begun by the late king. A war broke out between the Mexicans and Tlatelolcos, which ended in the final subjection of the latter. Their king was killed, and carried to the Mexican monarch, who, with his own hand, cut open his breast, and tore out his heart. He also fought the Otomies, and gained a complete victory, making 11,060 prisoners, among whom were three chiefs. He died in 1477, and was succeeded by his oldest brother, Tizoc, who was probably cut off by poison. Tizoc was succeeded by another brother, named Ahuitzotl, who finished the great temple begun by his predecessor, and, having reserved the prisoners taken in his wars for this purpose, he sacrificed, at its dedication, as Torquemada asserts, 72,344; others say, 64,060. This was in the year 1486. He carried on his conquests even as far as Guatemala, 900 miles south of Mexico. He was only once defeated; this was in 1496, by Toltecatl, a Huexotzincan chief. He died in 1502, in consequence of striking his head against a door. Two years previous to his death there was an inundation, which was followed by a famine, proceeding, it is said, from the decay of the grain.
