Résumé

A prominent explanation for Europe’s long history of political fragmentation and China’s tendency towards political unification is the fractured land hypothesis made famous by Diamond (1997a). We build a model to explore the effects of geography on political fragmentation. We find that topography, or fractured land, is necessary but not sufficient to account for China’s early political centralization and Europe’s persistent political fragmentation. The existence, or lack thereof, of a dominant core region of high land productivity also plays a critical role in explaining the political divergence at the two ends of Eurasia.
