Mesoamerica is a region and cultural area in the Americas, extending approximately from central Mexico to Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica, within which pre-Columbian societies flourished before the Spanish colonization of the Americas in the 15th and 16th centuries.here is extensive topographic variation in Mesoamerica, ranging from the high peaks circumscribing the Valley of Mexico and within the central Sierra Madre mountains to the low flatlands of the northern Yucatan YucatÃ¡n. peninsula
It was the initial emergence of the Olmec along the Gulf coast (1200 - 400 bce) that set many of the patterns of future civilization in Mesoamerica. Though isolated, it is clear that Mesoamerican civilization achieved some very impressive mathematical, architectural, engineering and calendrical advances.n addition, civilization in Mesoamerica did not have the cultural unity like that enjoyed by, for example, Egypt or China. There were several different societies in Mesoamaerica that rose and fell over time, (most widely known were the Olmec, Zapotec, Toltec, Mixtec, Mexica, Aztec, Inka).
