The Issue Correlates of War (ICOW) Project Supplementary Data Set: Colonial History Data Set

The ICOW colonial history data set attempts to identify colonial or other dependency relationships for each state over the past two centuries. This includes states that have ruled each state as a colony, dependency, League of Nations mandate, UN trust territory, or other type of possession, as well as states that have seceded from existing states and states that have merged into existing states. This should be most useful for analyses of a variety of possible propositions on the general impact of colonial rule on subsequent relations between the former colonizer and the former dependency, the impact of different countries' colonial policies on post-independence events (involving the former dependency and either internal problems or external relations with the former colonizer or with other states), and similar topics. It may also be useful in identifying cases for certain types of analysis (or perhaps \"relevant dyads\"), if former colonial powers are thought to have an interest in their former dependencies and their surroundings.

ICOW殖民史数据集（ICOW Colonial History Data Set）旨在识别近两个世纪以来每个主权国家的殖民或其他依附关系。该数据集涵盖将他国作为殖民地、依附领地、国际联盟委任统治地、联合国托管领土或其他类型属地进行统治的国家，以及从现有主权国家分离独立或并入现有主权国家的国家。本数据集可广泛应用于多类分析：包括检验关于殖民统治对前殖民宗主国与前依附领地后续关系普遍影响的各类命题、不同国家的殖民政策对前依附领地独立后事件（涉及该领地的内部问题，或是与前殖民宗主国、其他国家的对外关系）的影响，以及其他类似研究主题。若学界认为前殖民宗主国对其前依附领地及周边区域存在利益关联，本数据集还可用于为特定类型的分析（或所谓"相关二元组（relevant dyads）"）筛选研究案例。
