This is a fine collection of articles by outstanding scholars from various disciplines (law, history, theology and philosophy) and various continents (Asia, America and Europe). This work deals with interesting topics about universality and continuity in international law, ranging from universal validity to islamic international law. The work shows that research in the history of public international law cannot be limited to the development of modern public international law in a European perspective. It should cover the cultural traditions of other regions and traditions as well that tend to be increasingly integrated into current public international law.
