The International Crisis Behavior (ICB) Project is a project that collates interstate crisis data from 1918 (the end of World War I) onward to 2019.
[1] The project was created in 1975 by Michael Brecher and Jonathan Wilkenfeld.
The data for this version extends through 2019 and includes 496 international crises and 1,100 crisis actors.
[1] Data from the ICB has been referenced in a number of academic papers studying the patterns of conflicts and international crises.
[6] The Forecasting Principles website lists the ICB Project as an important data resource in the analysis of conflict and terror.
