Aztec Triple Alliance, Pre-colonial confederation in Central Mexico.
The Aztec Triple Alliance was a political union of three city-states in Central Mexico - Tenochtitlan, Texcoco, and Tlacopan - that ruled the Valley of Mexico. These states worked together to control territories and collect resources from subject peoples.
The alliance formed in 1428 following a successful revolt against Tepanec rule, which had previously dominated the region. After this turning point, the union rapidly expanded and became the dominant force in Mesoamerica until Spanish arrival in the 16th century.
The confederation shaped daily life through religious ceremonies held in temples that honored the gods and marked important moments. These practices were woven into festivals and rituals that brought communities together throughout the year.
Visitors explore today through archaeological sites and museums at places like Tenochtitlan in Mexico City, where remains and artifacts show the former power of these states. The best time is during dry months, and it helps to plan ahead since sites are spread across the city and surrounding areas.
The three partners divided tributes from conquered areas unequally, with Tenochtitlan receiving the largest share while the smaller city Tlacopan received considerably less. This unbalanced division later created tensions that contributed to the alliance's collapse when Spanish forces arrived.
