Why did the Aztecs build their capital city of tenochitlan in the middle of a lake?

The Aztecs built their capital city of Tenochtitlan in the middle of Lake Texcoco primarily for strategic and defensive purposes. The lake provided natural protection against invaders and allowed for easier control of trade routes. Additionally, the location facilitated the development of agriculture through chinampas, or floating gardens, which enhanced food production. This unique setting contributed to Tenochtitlan’s growth into a thriving urban center.
