  The history of human occupation in Mesoamerica is divided into stages or periods. These are known, with slight variation depending on region, as the Paleo-Indian, the Archaic, the Preclassic (or Formative), the Classic, and the Postclassic. The last three periods, representing the core of Mesoamerican cultural fluorescence, are further divided into two or three sub-phases. Most of the time following the arrival of the Spanish in the 16th century is classified as the Colonial period.
  
  The differentiation of early periods (i.e., up through the end of the Late Preclassic) generally reflects different configurations of socio-cultural organization that are characterized by increasing socio-political complexity, the adoption of new and different subsistence strategies, and changes in economic organization (including increased interregional interaction). The Classic period through the Postclassic are differentiated by the cyclical crystallization and fragmentation of the various political entities throughout Mesoamerica.
