Religion generally plays a major role in the partner countries of German development cooperation. However, religion does not always seem to be favorable for development and peace. Conflicts in countries such as Afghanistan, Iraq, Mali, Myanmar, Nigeria and Syria are often fought out between religious groups. Terrorist attacks by religious extremists are shaking Western countries and claiming even more victims in the Global South. This project investigates the causal relationships between religion, conflict, and peace and formulates recommendations for German development cooperation.
