Aztecs forge the Triple Alliance with Texcoco and Tlacopan
1345
The Mexica of Tenochtitlan joined with two lakeside city-states to overthrow their Tepanec overlords at Azcapotzalco. The resulting Triple Alliance would become the engine of Aztec imperial expansion, dividing tribute and conquered territories among three capitals on the shores of Lake Texcoco. Mesoamerica's last great empire was taking shape in the volcanic basin of central Mexico.
