Teotihuacan was an aggressive mercancile empire during Early Classic times. The Teotihuacan empire was larger, and lasted centuries longer, than the area controlled by either the later Toltecs or Aztecs (both of whose cultures borrowed extensively from Teotihuacan traditions). F.L.A.A.R. has devoted many years of research to learning more about Teotihuacan, the art of the imperial home city, and the art of its farflung provinces. Check out any of the directories of links of this or other F.L.A.A.R. web sites for Tiquisate, the largest Teotihuacan province outside of Central Mexico (Tiquisate was in the Costa Sur region of Guatemala).
