In the midst of other troubles came the news that Huehuetzin was marching at the head of the rebel forces towards Tollan, and was already most successful on the northern frontier. The other two lords from the gulf coasts, who had refused to acknowledge the power of Acxitl, were in league with Huehuetzin. Unable to resist this formidable army, the Toltec king was compelled to send ambassadors bearing rich presents to sue for peace,--according to the Spanish writers at the capitals of the distant rebellious provinces; but as Brasseur says to the headquarters of the hostile army not very far from Tollan. The presents were received, but no satisfactory agreement seems to have been made at first. Veytia and Ixtlilxochitl speak vaguely of a truce that was concluded as a result of this or a subsequent embassy, to the effect that the Toltecs should not be molested for ten years, an old military usage requiring that ten years should always intervene between the declaration of war and the commencement of hostilities; and the latter states that the army was withdrawn in the meantime, because sufficient supplies could not be obtained in the territory of the Toltecs. Brasseur, without referring to any other authorities than those named, tells us that after remaining a whole year near Tollan, Huehuetzin was forced to return to his own province to repel the invasions of hostile tribes, which tribes, it is implied, were induced to come southward and to harass the Toltec nations.[IV-67]
Taking advantage of the precarious condition of the Toltecs, many of the tribes even in and about Anáhuac shook off all allegiance to the empire, and became altogether independent; and at the same time numerous Chichimec tribes from abroad took advantage of the favorable opportunity to secure homes in the lake region. These foreign tribes are all reported to have come from the north, but it is extremely doubtful if any accurate information respecting the invaders has been preserved. For the conjecture that all or any of them came from the distant north, from California, Utah, or the Mississippi Valley, there are absolutely no grounds; although it is of course impossible to prove that all came from the region adjoining Anáhuac. By far the most reasonable conjecture is that the invaders were the numerous Nahua bands who had settled in the west and north-west, in Michoacan, Jalisco, and Zacatecas, about the same time that the nations called Toltecs had established themselves in and about Anáhuac. Brasseur finds in his authorities, the only ones that give any particulars of the invaders, that among the first Chichimec bands to arrive were the Acxotecas and Eztlepictin, both constituting together the Teotenancas. The Eztlepictin settled in the valley of Tenanco, south of the lakes, while the Acxotecas took possession of the fertile valleys about Tollan. A war between Nauhyotl II. of Culhuacan and the king of Tollan is then vaguely recorded, in which Acxitl was victorious, but is supposed to have suffered from the constant hostility of Culhuacan from that time forward, although that kingdom soon had enough to do to defend her own possessions. The Eztlepictin introduced a new divinity, and a new worship, which Acxitl, as successor of Quetzalcoatl made a desperate effort to overthrow. He marched with all the forces he could command to Tenanco, but was defeated in every battle. What was worse yet, during his absence on this campaign, the Acxoteca branch of the invaders were admitted, under their leader Xalliteuctli, by the partisans of Tezcatlipoca into Tollan itself. Civil strife ensued in the streets of the capital between the three rival sects, until Tollan with all her noble structures was well-nigh in ruins. At the same time wars were waged between the three allied kingdoms, and pest and famine came once more upon the land. These events occurred between 1040 and 1047.[IV-68]
