King Arthur, the Round Table and the Fight against War: At first sight it may seem like a contradiction to understand Arthurian epic as a medium against war. But this tendency manifests itself in some 20th century Arthuriana. The article's main focus lies on T.H. White's "The Once and Future King" (1958). In this novel young King Arthur learns to use chivalry and the round table as means of building a peaceful society and prevent war. But in the end, he must realize that his golden age of cuivalric values is doomed. Reflections of White's theme of prevention of war can also be found in Donald Barthelme's "The King" (1990).
