Xolotl divided his dominions into three states, namely, Azcapozalco, eighteen miles west of Tezcuco, Xaltocan, and Coatlichan, which he conferred, in fief, on his three sons-in-law. As was natural, various civil wars afterwards occurred during the reigns of the sovereigns who succeeded Xolotl. Nopaltzin reigned thirty-two years, and is said to have died at the advanced age of ninety-two. After him came Tlotzin, who reigned thirty-six years, and was a good prince. He was succeeded by Quinatzin, a luxurious tyrant, who, on the removal of his court from Tenayuca to Tezcuco, caused himself to be borne thither in a litter by four lords, while a fifth held an umbrella over him to keep off the sun; he is said to have reigned sixty years. In his reign, there were many rebellions, and on his death he was succeeded by a prince named Techotlala. In the year 1160, the Mexicans, Aztecas, or Aztecs made their appearance. They are said to have come from the region north of the Gulf of California, and were induced to migrate from the country where they lived by the persuasion of Huitziton, a man of great influence among them. He is said to have observed a little singing-bird, whose notes sounded like _Tihui_, which in their language meant, _Let us go_. He led another person, also a man of influence, to observe this, and they persuaded the people to obey the suggestion, as they said, of the secret divinity. This was no difficult matter in a partially civilized and superstitious community. They proceeded, as their tradition relates, to the River Gila, where they stopped for a time, and where, it is affirmed, remains have been found at a somewhat recent date. They then removed to a place about 250 miles from Chihuahua, toward the north-northwest, now called in Spanish _Casas Grandes_, on account of a large building found there, on the plan of those in New Mexico, having three floors with a terrace above them, the door for entrance opening on the second floor, to which the ascent was by a ladder. Other remains, also, of a fortress, and various utensils, have been found there. From this spot they proceeded southward, crossed the mountains, and stopped at Culiacan, a place on the Gulf of California in Lat. 24° N. Here they made a wooden image, called Huitzilopochtli, which they carried on a chair of reeds, and appointed priests for its service. When they left their country, on their migration, they consisted of seven different tribes; but here the Mexicans were left with their god by the others, called the Xochimilcas, Tepanecas, Chalchese, Colhuas, Tlahuicas, and Tlascalans, who proceeded onwards. The reason of this separation is not mentioned, except that it was at the command of the god, from which it may be conjectured that some quarrel had arisen with respect to his worship.
