The Aztecs founded Tenochtitlan in 1325 CE, guided by a prophecy of an eagle on a cactus. This vision became a powerful symbol, later appearing on Mexico's flag. The city's location in Lake Texcoco presented unique challenges and opportunities for settlement.
Innovative agricultural techniques, like chinampas, revolutionized farming in the lake environment. These artificial islands supported intensive crop cultivation, allowing for population growth and urbanization. The first tlatoani, Acamapichtli, established the ruling dynasty and strengthened Tenochtitlan's power.
