Atotoztli I

Atotoztli I was a Colhua princess of Culhuacan, a daughter of King Coxcoxtli and sister of King Huehue Acamapichtli. She married Opochtli Iztahuatzin, a Mexica leader, in one of the unions between the two peoples at Tizaapan. The Colhua nobility claimed descent from the Toltecs of Tula.

After Tenoch's death, the Mexica elders sought a ruler who could strengthen their new city's ties to powerful neighbours. They chose her son Acamapichtli, who became the first tlatoani of Tenochtitlan and founded its royal dynasty. The Codex Aubin dates his accession to 1376, while other chronicles differ.
