North America's Arizona-Mexico border represented the outer rim of Mesoamerican civilization in the pre-Columbian period, and later became the northern frontier of Spanish-Indian exchange following the European conquest of Mexico. The Arizona State Museum recently opened a long-term exhibition centering around the region, entitled Many Mexicos: Vistas de la Frontera, which strives to interpret the broad sweep of Mexican history from the pre-Columbian epoch to the political disputes of today, all through the particular lens of Arizona and its borderlands.
