Historical Acoma economic practices are described as socialistic or communal. Labor was shared and produce was distributed equally. Trading networks were extensive, spreading thousands of miles throughout the region. During fixed times in the summer and fall, trading fairs were held. The largest fair was held in Taos by the Comanche. Nomadic traders would exchange slaves, buckskins, buffalo hide, jerky, and horses. Pueblo people would trade for copper and shell ornaments, macaw feathers, and turquoise. The Acoma would trade via the Santa Fe Trail starting in 1821, and with the arrival of railroads in the 1880s, the Acoma became dependent on American-made goods. This dependency would cause traditional arts such as weaving and pottery making to decline.
