Classic Maya collapse

In archaeology, the classic Maya collapse is a model to describe the destabilization of Classic Maya civilization and the violent collapse and abandonment of many southern lowlands city-states between the 7th and 9th centuries CE. Modern scholars increasingly describe this period as a "rupture" or transformation rather than a true collapse, because a number of Maya cities survived even if they faced a period of instability. The Classic Period of Mesoamerican chronology is generally defined as the period from 250 to 900 CE, the last century of which is referred to as the Terminal Classic. The Classic Maya collapse is one of the greatest unsolved mysteries in archaeology. Urban centers of the southern lowlands, among them Palenque, Copán, Tikal, and Calakmul, went into decline during the 8th and 9th centuries and were abandoned shortly thereafter. Archaeologically, this decline is indicated by the cessation of monumental inscriptions and the reduction of large-scale architectural construction at the primary urban centers of the Classic Period. Although termed a collapse, it did not mark the end of the Maya civilization but rather a shift away from the Southern Lowlands as a power center; the Northern Yucatán in particular prospered afterwards, although with very different artistic and architectural styles, and with much less use of monumental hieroglyphic writing. In the Post-Classic Period following the collapse, the state of Chichén Itzá built an empire that briefly united much of the Maya region, and centers such as Mayapán and Uxmal flourished, as did the Highland states of the Kʼicheʼ and Kaqchikel Maya. Independent Maya civilization continued until 1697 when the Spanish conquered Nojpetén, the last independent city-state. Millions of Maya people still inhabit Guatemala and the Yucatán Peninsula today. Because parts of Maya civilization unambiguously continued, a number of scholars strongly dislike the term "collapse".
