The appearance of regional city-states in pre-Hispanic Central Mexico corresponds with the disruption of socioeconomic relationships throughout Teotihuacán's political domain after 650 A.D. Surface reconnaissance and mapping at Xochicalco provided information on the growth and organization of one of these urban centers. The data indicate that Xochicalco was a well-planned urban center and capital of a regional city-state that extended its domain throughout western Morelos by military conquest.
