In this article, we present the most up-to-date, fine-grained, global dataset on external support in armed conflicts: the UCDP External Support Dataset (ESD). The dataset encompasses data on states and non-state actors as both supporters and recipients and provides detailed information on the type of support provided to warring parties in armed conflicts between 1975 and 2017. We use it to highlight three broader trends in the provision of external support: (1) a dramatic increase in the number of external supporters, (2) a larger share of pro-government interventions, and (3) the rise of direct military intervention as the predominant mode of external support. In conclusion, we identify several avenues worthy of future inquiry that could significantly improve our understanding of external support in armed conflicts.

在本文中，我们介绍了有关武装冲突中外部支持的最新、细粒度的全球数据集：UCDP 外部支持数据集 (ESD)。该数据集包含作为支持者和接受者的国家和非国家行为者的数据，并提供了有关 1975 年至 2017 年期间在武装冲突中向交战方提供的支持类型的详细信息。我们用它来强调提供外部援助的三个更广泛的趋势支持：（1）外部支持者的数量急剧增加，（2）亲政府干预的比例更大，以及（3）直接军事干预作为外部支持的主要方式兴起。总之，我们确定了一些值得未来研究的途径，这些途径可以显着提高我们对武装冲突中外部支持的理解。
