Major arms imports and the onset of civil and ethnic wars in the postcolonial world, 1956–1998: A preliminary reassessment

This study examines the effects of states’ major arms imports from major powers on the likelihood of civil and ethnic wars in the postcolonial world. Focusing on civil and ethnic wars, respectively, in postcolonial states from 1956 through 1998, this investigation reveals that major arms imports from major powers have no statistically significant effect on either civil or ethnic war onset, considering political, economic, demographic, and geographic factors. The results also demonstrate that there are some different causal mechanisms between the onset of civil and ethnic wars. Finally, this article discusses policy implications and suggests some directions of the further research.
