  General Description   The Basin or Valley of Mexico is a highlands plateau in central Mexico roughly corresponding to modern-day Mexico City. Here, we are interested in the phase of its prehistory known as the Middle Postclassic (c. 1200-1426 CE). By this time, Tula no longer held sway over the region, and had been replaced by several city-states (altepetl). Documents written much later record the dynastic histories and conflicts between these city-states; toward the very end of this period, they came to form growing confederations, paving the way for the Aztec empire. [1] Major centres such as Azcapotzalco, Texcoco, or Cholula likely had between 20,000 and 30,000 inhabitants. [2] Each altepetl was ruled by a king (tlatoani) and a council of nobles. [3]
