Swidden agriculture,village longevity,and social relations in Formative central Tlaxcala: Towards an understanding of macroregional structure

Understanding social change within early village societies requires analysis at multiple scales. In this paper, we focus on macroregional structure in the Formative era of Central Mexico, based on excavations at village sites in Tlaxcala. A macroregional scale is particularly important for contextualizing developments in the study region. Rapid political evolution after 900 BC built on a legacy of organizational innovations in settled communities to the south. The earliest farmers in central Tlaxcala practiced a system of swidden agriculture developed at lower-lying elevations. Practiced on the erodible slopes of central Tlaxcala, that system led to the widespread degradation of farmland. Consequences at the village scale involved chronic instability of settlement and recurring localized stress on faunal resources.
