Relations Between the Jin, Liaos and Song Empires: Institutionalization of New Interaction Forms

This article examines the complex interplay between the Song, Liao, and Jin empires during the X– XIII-th centuries, focusing on the institutionalization of new forms of economic and political interaction. The study highlights the transformative processes of this era, including the economic revolution under the Song Dynasty, characterized by market development, monetary innovations, and technological advancements. The author challenges traditional Sinocentric narratives by demonstrating that the exchange between sedentary Chinese and nomadic societies was bidirectional: while the Liao and Jin adopted Chinese administrative and economic practices, the Song, in turn, incorporated elements of nomadic governance and production methods. A pivotal moment was the Treaty of Chanyuan (1005), which established unprecedented parity between the Song and Liao, marking a diplomatic revolution in Chinese history. The article also explores the role of trade – both official and illicit – as a stabilizing force in regional relations, despite strict state regulations that inadvertently fueled smuggling networks. The discussion extends to the concept of "international public goods", applied here to the tributary system, which provided stability and mutual benefits despite its hierarchical structure. The author critically evaluates the debate surrounding the "Sinicization" of the Jin Empire, questioning whether the adoption of Chinese institutions contributed to its decline or if internal strife and external pressures were more decisive. The geopolitical miscalculations of the Song, particularly its alliance with the Jin against the Liao, are analyzed as cautionary examples of short-term gains undermining long-term stability. By integrating institutional theory, the study reveals how path dependence, formal and informal rules, and external shocks shaped the evolution of East Asian polities. Ultimately, this research underscores the hybrid institutional innovations emerging from the interaction of sedentary and nomadic societies, offering insights into the dynamics of historical and modern international systems.
