The Chronology of Conquest: Implications of New Radiocarbon Analyses from the Cañada de Cuicatlán, Oaxaca

Abstract

Recently obtained radiocarbon determinations from the Cañada de Cuicatlán, Oaxaca, Mexico, have made it possible to revise the chronological placement of the Perdido phase (from 600-200 B. C. to 750-300 B. C.) and the Lomas phase (from 200 B. C.-A. D. 200 to 300 B. C.-A. D. 200), the latter being the phase for which substantial evidence of a Zapotec conquest of the Cañada has been recovered. The revised chronology brings the Lomas phase into close alignment with the Late Monte Albán I (300-100 B. C.) and the Monte Albán II (100 B. C.-A. D. 200) phases, during which the early Zapotec state emerged with its capital at Monte Albán in the Oaxaca Valley. The new Cañada dates support the proposition that territorial expansion outside the Oaxaca Valley played a major role very early in the process of Zapotec primary state formation. This strategy of extra-Valley expansion appears to have been initiated before all areas within the Oaxaca Valley were fully integrated into the Zapotec state.
