Explanation:

Teotihuacan is a city-state that existed in a sub-valley of the Valley of Mexico. It existed from around 150 BC, until the 7th or 8th century, though the end of this civilization is not really known. It was the biggest city in the Americas in its time, and one of the biggest cities in the world, having more then 125,000 inhabitants. This civilization was not a war-like one, but instead it seems to used diplomacy, knowledge, culture, trade, in order to be in good relations with the other civilizations and to prosper. The ethnicity of the inhabitants is not known, and it is believed that people of few different ethnic groups actually lived together. The city is known for its monumental buildings, as well as the cultural influence that it had in the region, especially with the Maya and Aztec civilizations.
