International Crisis Behavior Project

The International Crisis Behavior Project (ICB) gathers and analyzes data on international crises and crisis actors since the end of the First World War.  The ICB Version 11 datasets are now available. With the addition of 15 crises between 2008 and 2013, the ICB data now cover 1918 to 2013. This consists of 470 crises and 1,036 crisis actors.

The new data also incorporate a number of changes to previous crises, based on a systematic cleaning process aimed to improve the consistency of coding across cases. These changes are detailed in the release notes that can be downloaded from the data collections page. The previous versions of the data remain available for replication purposes.

After decades of tremendous stewardship by founders Michael Brecher and Jonathan Wilkenfeld, the leadership of the ICB project has transitioned. The new co-directors are Patrick James, of the University of Southern California, and Kyle Beardsley, of Duke University. Professors Brecher and Wilkenfeld are assuming the roles of senior advisors on the project. David Quinn has served as the ICB Project Manager throughout this transition.
The ICB Data Viewer is still in the process of being updated. It remains useful to explore the content of the crises in the previous version of the dataset (Version 10). The crisis summaries for the 15 new crises can be found on the data collections page, linked above.
