• Formation of the Aztec Empire
In 1428, after its successful conquest of Azcapotzalco, Tlacopan allied with the neighbouring city-states of Tenochtitlan and Texcoco, thus becoming a member of the Aztec Triple Alliance and resulting in the subsequent birth of the Aztec Empire.:xxxviii
Aculnahuacatl Tzaqualcatl, the son of the Tepanec ruler, Tezozomoc, was installed as tlatoani of Tlacopan until his death in c.1430. Throughout its existence, Tlacopan was to remain a minor polity within the Triple Alliance. It received only a fifth of tribute earnt from joint campaigns with its more powerful allies.
In 1521, The Aztec Empire collapsed as a result of the Spanish conquest of Mexico, led by Hernán Cortés and his native Tlaxcallan allies. Over the next few centuries, Tlacopan has been assimilated into the sprawling mega-metropolis of Mexico City. The archæological site of Tlacopan is located in Tacuba, within the present-day municipality of Miguel Hidalgo.
