This study examines the centralization and territorialization of state power in early China by analyzing the long-term developments in the sociopolitical structures, spatial organization, and political economy of the Qi 齊 state in present-day Shandong Province. It argues that the rise of the centralized and autocratic territorial states of Warring States China (453–221 BCE) was underpinned by the emergence of a particular matrix of sociopolitical and economic institutions that were, in a departure from the lineage- and kin-based power structures prevalent in the early first millennium BCE, predicated on certain principles of territoriality including direct infrastructural and administrative control over lands, populations, and resources. To demonstrate this shift, this study synthesizes a wide range of paleographic, archaeological, received textual, and numismatic evidence to offer a fundamental reassessment of the spatial and institutional dynamics of state power in Qi over the course of the first millennium BCE. Chapter 1 broadly examines the longue durée changes in the organization of the power structures and state institutions most prevalent across the Zhou world. It focuses especially on two main institutions: (1) the Zhou lineage system upon which the sociopolitical order of the Zhou ecumene was based until it lapsed into obsolescence toward the final few centuries of the Zhou period, and (2) the land tenure systems based upon the Zhou lineage order that correspondingly transitioned from one in which state lands were partitioned on the basis of aristocratic lineage settlements to one in which they were centrally reorganized into standardized and multi-tiered territorial-administrative units. Chapter 2 interrogates bronze inscriptions, archaeological data, and received texts to establish the geographic parameters of Qi territorial expansion from the initial Qi core region in present-day Zibo first across northern Shandong and then eventually into adjacent regions in eastern and southern Shandong.
