HIIK
The Heidelberg Institute for International Conflict Research (HIIK) at the Department of Political Science at the University of Heidelberg is a non-profit registered association that was established in 1991. It is dedicated to the distribution of knowledge over the emergence, course, and settlement of interstate and intrastate political conflicts. Its research outcomes have been published since 1991 in the Conflict Barometer as an annual analysis of the global conflict events and can be called up via a publicly accessible database. It lists intra-state and international political conflicts as of the year 1853 and distinguishes five levels of intensity. The first two levels of conflict, dispute and non-violent crisis, deal with non-violent conflict. The next three levels, violent crisis, limited war and war describe violent conflict. All conflicts are related to one or more conflict issues, such as the conflict issue "natural resources."
