If you want to know what the British – the educated British – thought of the Germans in 1914 here’s your answer:
The chief importance of the Zabern incidents, of the Strassburg trials, and of the exhibition of reactionary and particularist passion which has followed them in Prussia, is not in themselves. It lies in their significance as symptoms of the obstacles which still impede the moral unity of Germany. They reveal the persistence of not only of a profound division between the conquered provinces and Prussia, but of such a division between the whole legal and constitutional conceptions of South Germany and those that prevail amongst the Prussian aristocracy. These divisions are not new. They go back to the annexation of Alsace-Lorraine and to the establishment of modern States and the introduction of modern ideas by NAPOLEON in the south…
But the feudal nobility, and especially the nobility beyond the Elbe, have always set their faces against it and striven to shut their eyes to the change… Their devotion to the Throne and to the country, their lofty sense of public duty, their zeal, and their professional attainments are undoubted. But many of them inherit also the narrowness and the arrogance of a military caste.
Is it accurate? I think so, primarily because it explains the Zabern Incident so well.
Was it the cause of the war? It was certainly a cause. It wouldn’t be the first time that an unpopular regime that found itself cornered attempted to prop itself by starting a war. Milosevic’s Yugoslavia springs to mind as another example.
What it doesn’t explain is how such a divided nation was able to keep going for so long.
