Cuicuilco Dominates the Basin
A thriving city of pyramids and plazas rises on the southwestern shore of the lake. Its round pyramid, built without metal tools, becomes the religious heart of the valley until the volcano Xitle erupts around 100 BCE, burying it in lava and shifting power northward. The smell of sulfur and the sight of blackened fields would haunt local memory for centuries.

Founding of Tenochtitlan
According to legend, the Mexica see an eagle perched on a cactus devouring a snake on a small island in Lake Texcoco. They drive wooden piles into the mud and begin building what will become one of the world's largest cities. Within two centuries its population swells to between 100,000 and 200,000, crisscrossed by canals and connected by four great causeways.

Birth of the Triple Alliance
Tenochtitlan, Texcoco, and Tlacopan form a military and economic pact that rapidly expands into an empire stretching across central Mexico. Tribute flows into the island capital: jade, feathers, cacao, and captives for the gods. The city grows richer and more stratified with every campaign.

Templo Mayor Rededication
Emperor Ahuízotl inaugurates the final enlargement of the Great Temple with the sacrifice of thousands of captives. The twin shrines to Huitzilopochtli and Tlaloc tower over the sacred precinct. Their stepped silhouette against the lake remains the most potent image of Aztec imperial power.
