From this time to the date of the Spanish conquest in 1520, the confederate tribes were almost constantly at war with the surrounding Indians, and particularly with the feeble village Indians southward from the valley of Mexico to the Pacific, and thence eastward well towards Guatemala. They began with those nearest in position, whom they overcame, through superior numbers, and concentrated action, and subjected to tribute. These forays were continued from time to time for the avowed object of gathering spoil, imposing tribute and capturing prisoners for sacrifice, until the principal tribes within the area named, with some exceptions, were subdued and made tributary.26

The territory of these tribes, thus subject to tribute, constitutes what is generally known as the Mexican Empire.27 But, manifestly, it is an abuse of language to so designate this territory. No attempt was made for the formation of a State which would include the various groups of aborigines settled in the area tributary to the confederacy. “No common or mutual tie connected these numerous and diverse tribes,” excepting hatred of the Mexican confederacy. The tribes were left independent under their own chiefs. They well knew the tribute must be forthcoming, or else they would feel the weight of their conquerors’ displeasure. But such a domination of the strong over the weak, for no other reason than to enforce an unwilling tribute, can never form a nation, or an empire.28 These subject tribes, held down by heavy burdens—inspired by enmity, ever ready to revolt—gave no new strength to the confederacy: they were rather an element of weakness. The Spaniards were not slow to take advantage of this state of affairs. The tribes of Vera Cruz, who could have imposed an almost impassable barrier to their advance through that section, were ready to welcome them as deliverers.29 The Tlascaltecans, though never made tributary to the Mexicans, had to wage almost unceasing war for fifty years preceding the coming of the Spaniards. Without their assistance, Cortez would never have passed into history as the conqueror of Mexico.

A word as to the real power of the Mexicans. Their strength lay more in their defensive position than any thing else. As we have just stated, the entire forces of the confederacy were unable to subject the Tlascaltecans, the Tarasca of Michhuacan were fully their equal in wealth and power. The most disastrous defeat that ever befell the forces of the confederacy was on the occasion of their attack upon this last-named people in 1479. They fled from the battle-field in consternation, and never cared to renew the attempt. As to the actual population of the Pueblo of Mexico, the accounts are very much at variance. Mr. Morgan, after taking account of their barbarous condition of life—without flocks and herds, and without field agriculture, but also considering the amount of tribute received from other tribes—considers that an estimate of two hundred and fifty thousand inhabitants in the entire valley would be an excessive number. Of these he would assign thirty thousand to the Pueblo of Mexico.30

This is but an estimate. In this connection we are informed, that, when the forces of the confederacy marched against Michhuacan, as just stated, they counted their forces, and found them to be twenty-four thousand men. This includes the forces of the three confederate tribes, and their allies in the valley, and would indicate a population below Mr. Morgan’s estimate. The Spanish writers have left statements as to the population of Mexico which are, evidently, gross exaggerations. The most moderate estimate is sixty thousand inhabitants; but the majority of the writers increase this number to three hundred thousand.

The main occupation of the Aztecs, then, was to enforce the payment of tribute. From the limited expanse of territory at the disposal of the Mexicans, and the unusually large number of inhabitants for an aboriginal settlement, as well as the natural inclination of the Mexicans, they were obliged to draw their main supplies from tributary tribes. It is human for the strong to compel the weak to serve them. The inhabitants of North America were not behind in this respect.31 This is especially true of the civilized tribes of Mexico and Central America. The confederacy of the three most powerful tribes of Mexico was but a copartnership for the avowed purpose of compelling tribute from the surrounding tribes, and they were cruel and merciless in exacting the same.

Our information in regard to this tribute is derived almost entirely from a collection of picture writings, known as the Mendoza collection, which will be described more particularly when we describe their picture writings. The confederacy was never at a loss for an excuse to pounce upon a tribe and reduce them to tribute. Sometimes the tribe marked out for a prey, knowing their case to be hopeless, submitted at once when the demand was made; but, whether they yielded with or without a struggle, the result was the same—that is, a certain amount of tribute was imposed on them. This tribute consisted of articles which the tribe either manufactured, or was in situation to acquire by means of trade or war; but, in addition to this, it also included the products of their limited agriculture.

The same distribution of land obtained among all the civilized tribes that we have already sketched among the Mexicans. So, a portion of the territory of each conquered tribe would be set aside to be cultivated for the use of the confederacy. But, as the tribe did not have any land of its own, except for some official purpose, this implies that each gens would have to set aside a small part of its territory for such purpose. Such lots Mr. Bandelier calls tribute lots. These were worked by the gentes for the benefit of the Mexicans. It is to be noticed right here, that the Mexicans did not claim to own or control the land; this right remained in the gentes of the conquered tribe.

The miscellaneous articles demanded were generally such that they bore some relation to the natural resources of the pueblo. For instance: pueblos along the coast, in the warm region of country, had to furnish cotton cloth, many thousand bundles of fine feathers, sacks of cocoa, tiger-skins, etc. In other, and favorable locations for such products, the pueblos had to furnish such articles as sacks of lime, reeds for building purposes, smaller reeds for the manufacture of darts.
