I read James Charles Roy's The Vanished Kingdom because I have German family who fled from East Prussia during the end of World War II, and wanted to learn more about their experience and Prussian history. Without question, this book taught me many things I didn't know about before: the Teutonic Knights, the Battle of Grunwald/Tannenberg, the Polish Corridor, etc. It also contained several personal accounts from Germans who lived in East Prussia through WWII, thereby giving me additional perspective on the stories I've been told about the evacuation. As there aren't many books about Prussia out there, I value The Vanished Kingdom for that knowledge, although I probably could have found it just as easily on Wikipedia.
The Vanished Kingdom unquestionably merits only one star, however, because of its painfully obvious slant -- its pro-Prussia/Junker and anti-Polish sentiment is simply appalling. Mr. Roy seems to believe that Prussia is inherently German, and deserves to be taken from Poland/Russia and returned to unified Germany. He talks about the pride the Junkers took in maintaining their land, while consistently portraying Polish citizens as drunk, mean, suspicious, and incapable. He talks about how Prussia is inherently German, while skimming over the historical periods in which it was Polish. Worst of all, he spends ample time sharing stories of Polish anti-Semitism, while not telling stories about German anti-Semitism to the same extent. While I don't doubt that Polish people did plenty of evil things during WWII, highlighting those atrocities while neglecting to portray those of the Prussian Germans is clearly selection bias.
Some of the more troubling statements in The Vanished Kingdom come from Germans Mr. Roy interviewed, not himself. One interviewee, for example, literally calls Polish people "sub-human." A Jewish person claims he feared the Poles more than the Germans. Now, I don't believe we should hide from statements such as these, and pretend that such attitudes do not exist. The problem with The Vanished Kingdom, however, is that Mr. Roy never challenges them or place them within any sort of context. He simply lets these statements stand, and never attempts to shine a critical light on them. Morally, I find that unacceptable.
Published in 1999, The Vanished Kingdom is also showing its age. Mr. Roy seems to be setting up a future where a conflict between Germany and Poland/Russia over the former East Prussia simmers and ultimately erupts. Of course, this was before 9/11 and before Vladimir Putin planned to hold World Cup games in Kaliningrad. Still, predictions of the future that do not account for international terrorism or Putin strike this reader as coming from a time of innocence and naivete, without much relevance for a contemporary reader. Furthermore, the areas Mr. Roy visited have also advanced considerably. Berlin is modern and has a thriving arts scene. In 2009, Poland was the only EU country that did not slip into recession. German family of mine who have visited Poland have expressed how delightful they found it.
The Vanished Kingdom does have merit. That merit, however, is limited to the historical facts and personal accounts it contains, even though the facts can be incomplete and the accounts distasteful. Any further worth, however, is its worth as an example of bias, selective reporting, and historical whitewashing. I'd even almost recommend it on that ground alone, as I believe it's important to learn how history can be spun. This one will leave you dizzy.
