<P> Chichen Itza rose to regional prominence towards the end of the Early Classic period (roughly 600 AD). It was, however, towards the end of the Late Classic and into the early part of the Terminal Classic that the site became a major regional capital, centralizing and dominating political, sociocultural, economic, and ideological life in the northern Maya lowlands . The ascension of Chichen Itza roughly correlates with the decline and fragmentation of the major centers of the southern Maya lowlands . </P> <P> As Chichen Itza rose to prominence, the cities of Yaxuna (to the south) and Coba (to the east) were suffering decline . These two cities had been mutual allies, with Yaxuna dependent upon Coba . At some point in the 10th century Coba lost a significant portion of its territory, isolating Yaxuna, and Chichen Itza may have directly contributed to the collapse of both cities . </P> <Table> <Tr> <Td> </Td> </Tr> <Tr> <Th> Maya civilization </Th> </Tr> <Tr> <Td> <Ul> <Li> People </Li> <Li> Society </Li> <Li> Languages </Li> <Li> Writing </Li> <Li> Religion </Li> <Li> Mythology </Li> <Li> Sacrifice </Li> <Li> Cities </Li> <Li> Architecture </Li> <Li> Astronomy </Li> <Li> Calendar </Li> <Li> Stelae </Li> <Li> Art </Li> <Li> Textiles </Li> <Li> Trade </Li> <Li> Music </Li> <Li> Dance </Li> <Li> Medicine </Li> <Li> Cuisine </Li> </Ul> </Td> </Tr> <Tr> <Th> History </Th> </Tr> <Tr> <Td> Preclassic Maya </Td> </Tr> <Tr> <Td> Classic Maya collapse </Td> </Tr> <Tr> <Th> Spanish conquest of the Maya </Th> </Tr> <Tr> <Td> <Ul> <Li> Yucatán </Li> <Li> Chiapas </Li> <Li> Guatemala </Li> <Li> Petén </Li> </Ul> </Td> </Tr> <Tr> <Td> <Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> </Td> </Tr> </Table> <Tr> <Th> Maya civilization </Th> </Tr>
