Economic Integration and Obsidian Consumption in the Late Postclassic Period K'iche' Region.

Although much research has been conducted on the Late Postclassic period Maya, there has been relatively less study of the role of economic activities in political management during this period. Many such studies focused on obsidian analysis and technology as proxies for trade and exchange. This article builds on that research, using a legacy collection of obsidian implements collected during archaeological surveys in the 1970s to examine Late Postclassic period (AD 1200–1524) economic networks in the K'iche' region. Obsidian collections from the site of Q'umarkaj and the surrounding region were examined through technological and geochemical analyses. I find that during the Late Postclassic period, K'iche' elites had more access to nonlocal obsidian sources than did non-elites, but that access to locally available sources was managed through independent and diverse acquisition networks. Thus, the K'iche' elite were not dependent on local economies as a main source of political power. [ABSTRACT FROM AUTHOR]
