We examine the long-term pattern of state formation and the mythical historical Chinese unity under one single political regime based on the compilation of a large geocoded annual data series of political regimes and incidences of warfare between 221 BC and 1911 AD. Guided by a carefully constructed historical framework and narrative, we classify our data sets into two types of regimes – agrarian and nomadic – and three types of warfare– agrarian/nomadic, agrarian/agrarian and internal rebellions – and applying an Autoregressive Distributed Lag (ARDL) model, we find that nomadic-agrarian warfare and internal rebellion strengthens unification but agrarian/agrarian warfare entrenches fragmentation. Our paper offers a comprehensive analysis on both the historical processes and driving force leading to China’s eventual unity in a comparative and global context.
