The rapid growth in urban population at Teotihuacan initially resulted from a series of nearby volcanic eruptions that disrupted agriculture and forced rural villagers to relocate to the city. Later, as
the city elite increased their power, they forced additional farm families from the smaller villages in the region to relocate closer to the urban core. The elite organized these new labor resources to
bring marginal lands into production, drain swamps, construct irrigation canals, and build terraces into hillsides. They also expanded the use of chinampas, sometimes called "floating gardens."
