Joseph Berry Keenan Digital Collection The Joseph Berry Keenan Digital Collection—comprising manuscript materials and photographs—offers researchers invaluable insight into the Japanese War Crimes Trial—one of the most important trials of the twentieth century. The struggles of World War II did not end after the Japanese and German surrender to the Allied Powers; they merely shifted from land, air and sea battlefields to court rooms around the world. Thousands of defendants would be tried on various charges of conventional – and non-conventional - war crimes. The most famous of these trials were those held in Nuremberg and Tokyo. It was at these two trials, more than at any other, that a new chapter in international law would be written.
