Chichén Itzá dominated the political landscape of the northern Yucatán during the Terminal Classic Period (AD 800-1000). Chronological details of the rise and fall of this important polity are obscure because of the limited corpus of dated hieroglyphic records and by a restricted set of radiocarbon dates for the site. Here we compile these and review data and evaluate them within the context of political and climatic change in northern Yucatán at the end of the Classic period. The available data point to the end of elite activity at Chichén Itzá around AD 1000, a century after the collapse of Puuc Maya cities and other interior centers. Evidence supports a population shift in the eleventh century towards some coastal locations during a time associated with the end of monumental construction and art at Chichén Itzá. Our results suggest that regional political disintegration came in two waves. The first was the asynchronous collapse of multiple polities between AD 850 and 925 associated with a regional drying trend and punctuated by a series of multi-decadal droughts in the ninth and tenth centuries. The second wave was the political collapse at Chichén Itzá that coincides with the longest and most severe drought recorded in regional climate records between AD 1000 and 1100. This is a time that some scholars have characterized as a "dark age" across the northern Maya lowlands. Political developments during the Postclassic period (AD 1000-1517) correspond with a return to higher rainfall. These patterns support a strong relationship between political disintegration and climatic stress in the Maya lowlands. This research employs Bayesian radiocarbon models in conjunction with calendar dates on carved monuments and climate proxies to evaluate the rise and fall of Maya political centers and serves as an example of the impact of climate change on rainfall-dependent societies in Mesoamerica.

Exploring the long-term use of accounting practices and currencies by literate and numerate authorities contributes new information regarding the complexity of the political economy of ancient Maya society. Two forms of indirect, yet compelling, lines of evidence for accounting practices and currencies are presented in this article. First, we identify potential accounting devices (counting sticks and tokens) found in the tombs of royal scribes and nobles, based on the contextual associations and depicted uses of similar objects in Maya art such as polychrome vases and murals. Second, we argue that the long-term use and significant standardization of specific shell objects suggests their role as all-purpose monies, in addition to their complementary status as counting devices or numerical symbols. This paper addresses the intricate relationships between symbolism, value and multiple modes of exchange that have long been of interest to cross-cultural studies in anthropology.
