Mexico City is built on the same site as Tenochtitlán, which was the grand capital city the Aztecs built. It was divided into quarters, within which were separate districts for each group.
In 1500, the Aztec empire consisted of more than 10 million citizens. But in 1519-21, Hernan Cortes and his 500 Spanish troops destroyed the Aztec empire.
