Peace and its correlates in the ancient world
本文构建并分析了公元前600年至30年地中海地区的战争数据库，首次对该时期战争进行深入统计，检验民主与霸权对和平的解释力，发现古希腊城邦间不存在民主和平论，挑战了主流政治理论。
In this paper, we construct and analyze a database of warfare around the Mediterranean from 600 to 30 BCE. We provide the first in-depth statistical summary of war in this period, examining variation across space, time, and belligerents. Then we evaluate two main explanations for international peace: democracy and hegemony, using both statistical analyses and case study comparisons. We find no democratic peace among Ancient Greek city-states and mixed results, both inside and outside of Greece, about how war relates to state power. Broadly, our results challenge prominent political theories of peace and suggest more exploration of alternatives.
