Question: is teotihuacan the same as tenochtitlan?
Answer: Yes. Teotihuacan (150 B.C. - A.D. 750) is an older city than Tenochtitlan (approximately A.D. 1325–1521), in a completely different place and inhabited by totally separate people. Tenochtitlan was where present-day Mexico City is. It was the home of the “Aztecs” (Mexica).
