Sui-Tang China and Its Turko-Mongol Neighbors challenges readers to reconsider China's relations with the rest of Eurasia. Investigating interstate competition and cooperation between the successive Sui and Tang dynasties and Turkic states of Mongolia from 580 to 800, Jonathan Skaff upends thenotion that inhabitants of China and Mongolia were irreconcilably different and hostile to each other. Rulers on both sides deployed strikingly similar diplomacy, warfare, ideologies of rulership, and patrimonial political networking to seek hegemony over each other and the peoples living in thepastoral borderlands between them. The book particularly disputes the supposed uniqueness of imperial China's tributary diplomacy by demonstrating that similar customary norms of interstate relations existed in a wide sphere in Eurasia as far west as Byzantium, India, and Iran. These previously unrecognized cultural connections,therefore, were arguably as much the work of Turko-Mongol pastoral nomads traversing the Eurasian steppe as the more commonly recognized Silk Road monks and merchants. This interdisciplinary and multi-perspective study will appeal to readers of comparative and world history, especially thoseinterested in medieval warfare, diplomacy, and cultural studies.
