Men’s and women’s work fueled the increasingly sophisticated goods Aztecs produced and the large amounts of trade conducted and tribute paid by Aztecs. While much labor was performed at the household level, workshops grew in number. Craft production became more complex as population increased, political organization became more elaborate, and demand for goods increased. The increasing output of producers and growing number of commercial endeavors by merchants underwrote an increasingly rigid hierarchy. Women’s cooking and weaving fed and clothed ordinary families, Aztec armies, and royal palaces. The special province of women of all social levels, weaving created the most common and among the most valuable of tribute items, woven cloth. Other important forms of production included mining obsidian and making it into tools. Pottery production was crucial for cooking, eating, and carrying and using water among other uses. Both food producers and craftspeople, often one and the same, sold their wares in local markets. Economic descriptions often focus on long-distance trading by the pochteca and oztomeca (long-distance and spying merchants), but trading ranged from producer-sellers, selling goods in local marketplaces to the more illustrious pochteca and oztomeca. Those merchants traveled to distant regions to obtain luxury goods.
