International Crisis Behavior Project, 1918-2004

This data collection was produced as part of the International Crisis Behavior Project, a research effort aimed at investigating 20th-century interstate crises and the behavior of states under externally generated stress. To this end, the data describe, over a 86-year period, the sources, processes, and outcomes of all military-security crises involving states. Variables were collected at both the micro/state actor level and the macro/international system level. At the macro level, seven dimensions of crisis were measured: crisis setting, crisis breakpoint-exitpoint, crisis management technique, great power/superpower activity, international organization involvement, crisis outcome, and crisis severity. Additional macro-level variables indicate various aspects of geography, polarity, system level, conflict type, power discrepancy, and involvement by powers. At the state actor level, variables measuring five dimensions of crisis were compiled: crisis trigger, state actor behavior, great power/superpower activity, international organization involvement, and crisis outcome. Additional micro-level variables indicate the role of war in each crisis. Others measure several kinds of state attributes: age, territory, regime characteristics, state capability, state values, and social, economic, and political conditions.

本数据集系国际危机行为项目（International Crisis Behavior Project）的研究产出之一，该项目旨在探究20世纪国家间危机及外部压力下的国家行为。为此，本数据集记录了86年时间跨度内所有涉及主权国家的军事安全危机的缘起、进程与结果。数据集同时采集了微观/国家行为体与宏观/国际体系两个层面的变量。在宏观层面，共从七个维度对危机进行测度：危机背景、危机断点-终结点、危机管控手段、大国/超级大国行为、国际组织介入、危机结果与危机严重程度。额外的宏观层面变量涵盖地理特征、极格局、体系层级、冲突类型、权力差距以及大国介入等多个维度。在国家行为体层面，共整合了五个维度的危机测度变量：危机诱因、国家行为体行为、大国/超级大国行为、国际组织介入以及危机结果。额外的微观层面变量用于表征每场危机中的战争角色；其余变量则涵盖多项国家属性：国家存续时长、领土规模、政权特征、国家实力、国家价值观以及社会、经济与政治状况。
