Why did the Aztecs build the capital city?

The Aztecs built their capital city, Tenochtitlán, in the early 14th century primarily for strategic and agricultural reasons. Located on an island in Lake Texcoco, it offered natural defense against enemies and abundant resources for farming through chinampas, or floating gardens. The city's central location also facilitated trade and political control over the surrounding regions, allowing the Aztecs to expand their empire effectively. Additionally, Tenochtitlán became a religious and cultural hub, symbolizing the Aztec's power and identity.
