What we call Teotihuacan culture is the material expression of the society that emerged in the valley of Teotihuacan in central Mexico between 100 BC and 600 AD. For nearly 700 years the people of Teotihuacan transformed the environment to build one of the most complex cities of the ancient world. From this site departed caravans of traders and travelers to all corners of Mesoamerica, taking and bringing back goods, knowledge, information and raw materials, among many other things. The strategic location of the city made it possible for the people of Teotihuacan to obtain natural resources and to access the territorial corridors necessary for expansion and for contacting the other societies of their era, such as the Zapotecs and the Maya, with whom they shared a world view that included particularly powerful gods of land and water.
Furthermore they controlled the obsidian deposits close to the city, as may be seen in the vicinity of Otumba and Sierra de las Navajas in the present day state of Hidalgo. Thanks to these, they managed to control the exchange of objects vital to everyday living such as knives and cutting and pointed tools used in homes and craft workshops. In this way they consolidated a power base that lasted more than half a millennium.
