A general term referring to the period of time when a culture or civilization reaches its highest point of complexity and achievement. In a broader sense, the term often describes the whole period of Greek and Roman antiquity with the following breakdown: Early Classical Period 500-450 BC, High Classical Period 450-400 BC, and Late Classical 400-323 BC. Specifically, the term describes, in New World chronology, the period between the Formative (Pre-Classic) and the Post-Classic, which was characterized by the emergence of city-states. During the Classic stage, civilized life in pre-Columbian America reached its fullest flowering, with large temple centers, advanced art styles, writing, etc. It was originally coined for the Maya civilization, initially defined by the earliest and most recent Long Count dates found on Maya stelae, 300-900 AD. A division between Early and Late Classic was arbitrarily set at 600 AD, but since in some areas, e.g. Teothihuacan, great civilizations had already collapsed, some scholars regard this date as marking the end of the Classic Period. By extension, the word came to be used for other Mexican cultures with a similar level of excellence (Teotihuacán, Monte Albán, El Tajín). In these areas the cultural climax was roughly contemporary with that of the Maya, and the term Classic took on a chronological meaning as well. The full Maya artistic, architectural, and calendric-hieroglyphic traditions took place during the Early Classic. Tikal, Uaxactún, and Copán all attained their glory then. In the Late Classic, between 600-900 AD, ceremonial centers in the Maya Lowlands grew in number, as did the making of the inscribed, dated stelae and monuments. The breakdown of the Classic Period civilizations began with the destruction of the city of Teotihuacán in about 700 AD. Some date the Classic period to 300-900 AD.
