A variety of antagonistic, diplomatic, and

lineage-based networks are evident in historical texts (Munson and Macri, 2009) and economic linkages are evident in the archeological record with patterned distributions of exotic materials (e.g., obsidian, McKillop, 1996a, Braswell et al., 2000, Nazaroff et al., 2010, Golitko et al., 2012 and Moholy-Nagy et al., 2013). Polities were largely autonomous entities (e.g., peer-polities; Schele and Freidel, 1990, Carmean and Sabloff, 1996 and Webster, 1997), but subordinate relationships between centers became more frequent in the Late Classic (e.g., Calakmul’s subordination of multiple centers, see yellow lines in Fig. 2) and some have argued for a small number of strongly centralized states by this time (Marcus, 1976, Selleckchem Crenolanib Chase and Chase, 1996, Martin and Grube, 1995 and Martin and Grube, 2000). Texts indicate that status rivalry and warfare played a critical role in the rise and fall of individual political centers (Martin and Grube, 2000), and the reverberating effects of political failure were experienced most strongly by other polities nearby. In the central portions of the Maya lowlands (e.g., Central Petén, Belize, Yucatan, and Usumacinta-Pasion) densely aggregated political centers were tightly packed

(25–30 km spacing) ZD1839 ic50 and interconnected as a result of economic spacing of Maya cities. Dynastic succession was largely, but not entirely, patrilineal (see Schele and Freidel, 1990 for examples), and the most successful dynasties persisted for centuries once they were established

(most between AD 300 and 500), but started to fail in rapid succession after AD 750. Dated stone monument production, a proxy for the voracity of kingship dropped precipitously at several large centers between AD 780 and 800 (see Fig. 4). This was followed VAV2 by a 50% drop (from 40 to 20) in the number of centers producing monuments between AD 800 and 820 and continued to decline into the early part of the 10th century. Building campaigns ceased at these locations and associated populations dispersed. Some regions were depopulated rapidly (e.g., inland southern Belize), whereas some populations persisted into the Early Postclassic (until ∼AD 1000–1100) and even into the historic period (e.g., Lamanai, Graham et al., 1989; Wild Cane Cay, McKillop, 1989 and McKillop, 2005). There was an overall shift toward peri-coastal settlement and seaborne transport (Turner and Sabloff, 2012) during the Postclassic Period. Classic Period economic, social and political networks failed within ∼100 years during the 9th century across much of the southern and central Maya Lowlands and did not recover (Turner, 1990 and Turner and Sabloff, 2012). Classic Maya polities were founded upon a diverse array of food production systems that developed in response to regional differences in topography, geology, and hydrology (Fedick and Ford, 1990, Dunning et al., 2002 and Luzzadder-Beach et al., 2012).
