A regional investigation of the ancient Maya settlement patterns of the Puuc suggests that this region was occupied by increasing numbers of people seeking to maximize control over prime agricultural soils during the Late Classic period. During the Late Classic the eastern Puuc region was controlled by numerous autonomous major centers that carried on the Classic Maya tradition of divine kingship. During the late ninth century a.d., the city of Uxmal briefly emerged as the politically dominant center of the region and was involved in an important relationship with the city of Chichen Itza. By a.d. 950, however, Uxmal and the other major centers of the Puuc had ceased all important elite activities.
