Political Events Project, 1948-1965

This study contains data on 6,754 political instability events in 84 selected nations in the period 1948-1965. These data, which permit measurement of political instability and the correlates of internal conflict behavior, are concerned with conflict directed by groups and individuals in the prevailing political system against other groups or persons, and with uncovering the determinants of stability within all national political systems. The variables in the dataset are divided into four basic types: variables that identify events, classify events, describe events, and evaluate events. The study provides a conflict intensity rating for each event. Political instability events are classified from low to high and include institutionally prescribed elections, the fall of cabinets, martial laws, assassinations of significant group leaders, mass arrests, coup d'etats, and civil wars.

本研究涵盖了1948年至1965年间84个选定国家中6,754起政治不稳定事件的详细数据。这些数据允许对政治不稳定及其与内部冲突行为的关联进行测量，主要关注于现有政治体系内由团体和个人发起的对其他团体或个人的冲突，以及揭示所有国家政治体系内稳定性的决定因素。数据集中的变量被划分为四种基本类型：识别事件、分类事件、描述事件以及评估事件。研究为每个事件提供了冲突强度评级。政治不稳定事件按照从低到高的顺序进行分类，包括制度规定的选举、内阁垮台、军事管制、重要团体领导人的暗杀、大规模逮捕、政变以及内战。
