The present study aims at assessing the role of parliament in preventing, managing and resolving conflict. The assessment builds on field research conducted in four selected countries: Iraq, Lebanon, Sudan and Yemen. The selected countries have suffered from conflicts of either short or longer periods of time. In addition to the four cases of field research, the role of parliament in Algeria, a country that has faced internal instability for more than a decade, has been included to demonstrate the effectiveness of parliament in preventing, addressing and resolving the conflict.
