He is credited with the expansion and consolidation of the Aztec Empire (though he is often mistaken for his popular descendant Motecuhzoma II, who ruled during the Spanish conquest nearly a century later).
"[2] Under Motecuhzoma I's rule, Tenochtitlan began to solidify its place as the capital city of the Aztec (Mexica) Empire.
Motecuhzoma I's rule and military expeditions also coincided with a rise in ritual human sacrifice, reflected in the sacrificial well on the top of the monolith.
[3] The Stone of Motecuhzoma I was discovered in July 1988 under the colonial Archbishop's palace, or Palacio del Arzobispado, on Moneda Street in modern-day Mexico City.
The Palacio del Arzobispado was built in 1530 under the direction of Spanish Friar Juan de Zumárraga on the base of the destroyed Temple of Tezcatlipoca.
This placement was intentional — on the side panels of the stone, Motecuhzoma I is dressed as Tezcatlipoca dominating his enemies in battle.
[5] Surrounding the carving of Toniatuh is a band of concentric circles, representing the precious green stone, or jade.
On the outer band, there is an alternating pattern of jade and cuauhxicalli, or "eagle-box," the stone receptacles used to house human hearts after sacrifice.
In order, these kingdoms include Culhuacan, Tenayuca, Xochimilco, Chalco, Tamazulapan, Acolhuacan, Texaxic o Tepanoaya, Tlatelolco, Tonatiuhco, Mixtlan, and Cuetlaxtlan.
In his Historia de las Indias, Durán writes: "it was ordered that around [the stone] it should be depicted, as a border or frieze, every war they had fought up until then where the sun, with its protection and help, had granted them victories.
"[8] Friar Diego Durán seconds this account, writing that the Tlaltoani Motecuhzoma I invited common people from all over the valley of Mexico to attend the ceremonies.
