Mexico was formerly an empire of no great extent, but numerously peopled, and covered with towns; it was surrounded by several other states, either in alliance with it, or under its dominion. Of these the most noted were the Michuacan, Tlacopan, and the Acolhuacan kingdoms, the Cholollan, Huexotzincan, and Tlaxcallan republics, with several others of inferior note.

The boundaries of the Mexican kingdom were the small state of Quauhtemallan on the south-east; on the east, part of the above states and the Mexican gulf; on the north Huaxtecas, a country inhabited by a tribe of that name; Tlacopan, and a savage tribe, called the Chichemicas, were on the north-west; Michuacan on the west; and on the south and south-west the Pacific. This kingdom was therefore situated between the fourteenth and twenty-first degrees of north latitude, and between the ninety-seventh and the hundred and fifth degrees of west longitude. Of this extent, the most fertile and best cultivated portion was the vale of Anahuac, or of Waters, which embraced a beautiful district, comprised within mountains, the circuit of whose basis occupied 120 miles. From the name of this vale, the whole country received afterwards the appellation of Anahuac, previously to its settlement by the Spaniards, who called it New Spain; which title has since been given to the dominions of Spain, in North America, occupying the whole extent from the northern boundaries, to the kingdom of Guatimala, and often embracing that territory also. In the centre of the vale of Anahuac are the lakes of Tezcuco and Chalco, on whose banks were the cities of Mexico, Acolhuacan, Tlacopan, Tezcuco, and forty others, with innumerable small towns.

Michuacan, the westerly kingdom, had its capital on a lake, called Pascuaro, with four other cities. Tlacopan lay between Mexico and Michuacan, and its capital was Tezcuco, four miles west of Mexico. Acolhuacan, which was very extensive, as well as the most ancient of the kingdoms, had its capital on the eastern shore of Lake Tezcuco, at about fourteen miles from Mexico; this kingdom was powerful, populous, and contained many cities; it was amongst the most civilized of the territories of Anahuac. Tlaxcallan or Tlascala was on the south of Mexico, and the chief of the republics; it was not large, and its capital was situated seventy miles east of Mexico. The republics of Cholollan and Huexotzinco lay to the south of Tlaxcallan.

The origin of the Mexican nations, or the nations of Anahuac is very obscure, but it is supposed that the Toltecas, who inhabited a country to the north of Mexico were the most ancient inhabitants, of whom any trace could be found; and they had a tradition that they came from the north. A tribe of this nation being banished from the country where they dwelt, journeyed to the southward in search of a favourable spot whereon to fix their residence; it is asserted they commenced their migration in the year 596 A.D., but not finding a place which had charms enough to fix them, for any great length of time, they still kept removing to the south for the space of 104 years, when they came to a spot which pleased them. Here they erected a city, fifty miles eastward of the spot where Mexico the capital was afterwards founded. They rested twenty years in this place, when they again removed and settled forty miles farther west, building another city.

They appear to have been an industrious people, well skilled in many arts, and living under the government of their kings in a peaceable manner; but, unfortunately in the year 1052, suffered from a dearth and want of water, which pervaded their land; and a great part of their people died of famine. Those who remained, dispersed themselves into Guatimala, Mexico, &c. For the space of 100 years the Toltecan country was nearly a desert, very few having been left behind; after this interval the Cachemecas, another race from the north arrived, whose manners were not so cultivated, and their way of living more savage than the Toltecans. They established themselves in a place about six miles from the present city of Mexico, and were governed by kings, who encouraged their people to cultivate the friendship of the poor Toltecans who remained; in return for which they instructed them in all the arts they knew. This monarchy lasted till the year 1520, or nearly five centuries; the Toltecan monarchy having endured nearly four. Some other tribes from the north, of which the Acolhuans, and the Otomies were the principal, entered into alliance with the Cachemecas. After them the Tarascas and the Nahuatlacas, also from the north, settled in Anahuac. The Aztecas, or Mexicans, were the last; they came from a country beyond the gulf of California; this is said to have taken place in the year 1160, when they moved southward, and traces of the buildings they left, are said to exist on the banks of the Rio Colorado, and on the Rio Gila, &c. They stopped for some time at a place in New Biscay, about 250 miles north-north-west of Chihuahua, and there raised some large buildings, from which the place is now called Casas Grandes, which signifies large houses, and is in 29° north latitude. This large building is constructed with three floors, and crowned by a terrace; the lower floor has no door, and the upper is accessible only by a ladder, which is still the manner in which the buildings of New Mexico are constructed. This house, or fort, has been surrounded by a wall, seven feet thick, and in which enormous stones were used; the beams of pine are said still to exist. In the centre is a keep or mound; the whole has had a ditch about it, and earthen pots, jars, &c. with mirrors of the itzli stone, have been dug up in the neighbourhood. On leaving this spot, they crossed the mountains of Taraumara, and rested three years at Culiacan.

When the Aztecas left their native country, they consisted of six tribes, viz. the Mexicans, Tepanecas, Chalcese, Tlahuicas, Tlascans, and Xochimilcans. At Culiacan they constructed the image of the deity Huitzilopochtli, with a throne to carry it on the shoulders of four priests. The Mexicans were deserted by the five other tribes on quitting Culiacan, and journeying with their image, arrived at Tula, the capital which the Toltecans had built, erecting altars at all their resting places on the road. They stayed here, and in the vicinity, twenty years; and in 1216 they came to Zumpanco, a large town in the vale of Anahuac; here they were kindly received, and one of their chief women married Ilhuicatl, the son of the chief; from which marriage the race of Mexican emperors descended. They roamed about the borders of the lake Tezcuco, settling in different places, and at last engaged in wars with the Cachemicas and Acolhuans, and were obliged to take refuge in some islands called Acocolo, in the southern part of the Mexican lakes. Here they existed fifty-two years, in great poverty, and were finally enslaved by the chief of a small state called Colhuacan.

A few years after a war commenced between the Xochimilcans, one of the tribes who had separated from the Mexicans at Caliacan, and the Cholhuans, in which the Mexicans assisted their enslavers, and behaved so valorously as to gain their liberty. Their conduct was however stained by the cruelty they committed in the action, by cutting off their prisonersʼ ears, and by a human sacrifice, which they made to their divinity after the battle, which consisted of four of the prisoners whom they had reserved. The chief of the Cholhuans commanded them to quit his territory, being disgusted at their barbarity; they moved therefore to a place near the junction of Lakes Chalco and Tezcuco, which place they named Mexicaltzinco; they removed however from this to Iztacalo, nearer the place where Mexico was soon after built. Here they rejoiced for their victory and subsequent liberation, and remained two years, when wandering about, they discovered on an island, in the lake, a sign which their oracles had declared to be the mark of their future resting place; here they accordingly built some miserable huts of reeds, and having taken a Cholhuan prisoner, sacrificed him to their deity, built an altar, and prepared permanently to fix their residence. To this town and island they gave the name of Tenochtitlan, and afterwards building their huts round the altar of Huitzilopochtli or Mexitli, they gave the town the name of Mexico, or the city of Mexitli, their god of war. This took place in the year 1825.

The situation of their new town, chosen solely from the omen, was as uncomfortable and as ill-placed, as they could have found on a small island, in a lake without ground for cultivation, or much space for building. There they lived long in a very wretched manner, till at last, impelled by necessity, they drove stakes and made dykes to the neighbouring islets; by which means they shut out the water, and connected the islands, so as to gain considerable space from the lake. By industry they attained sufficient quantities of materials from the neighbouring settlements to erect their habitations and furnish themselves with necessaries, and constructed floating gardens on the water, with the mud of the lake and branches of trees, on which they raised vegetables, &c. Struggling with great distress and difficulties, they remained unanimous and constant in their exertions for thirteen years, when an old quarrel was renewed amongst themselves, and they divided into two factions, who separated, one remaining on the spot, the other going to an island in the vicinity, which they named Tlatelolco, and which was afterwards united to the other by mounds. The original town was now divided into four quarters, and in the centre was built the temple of Mexitli.

They remained in great barbarism for some time, and sacrificed a daughter of the king of Cholhuacan, whom they had invited into their town, under a specious pretext; on which the king declared war against them, but they were now as powerful as himself. Their government had been hitherto an aristocracy; the nation obeying a council of their great chieftain. At this era they found that a monarchy was best suited to their views, as well because their neighbours had mostly adopted that form of government, as because their territories consisting only of the city, one person was better able to perform the duties of the kingly office than several. They therefore elected Acampatzin for their king and leader, who was descended from the race above mentioned.

This prince took a daughter of Acolmiztli, king of Coatlican, for his consort; their rival brothers, the Tlatelolcos also chose a king, the son of the king of the Tepanecans, and in consequence of their choosing the son of this prince, who had hitherto received tribute from both parties, they endeavoured to instigate him to make war on the Mexicans; he however, only doubled their tribute, and otherwise oppressed them very much, for fifty years; during thirty-seven of which, Acamapitzin governed Mexico. He took another wife, and had by her a son Huitzilihiutl, and by his concubines several children, of whom Itzcoatl was afterwards one of the most renowned.
