The Black Cross: A History of the Baltic Crusades
A wide-ranging new history of the Baltic Crusades and their legacy
Between the twelfth and fifteenth centuries, crusading armies unleashed a relentless holy war against the last pagan societies in northern Europe, particularly in the Baltic Sea region. Led by Catholic rulers, churchmen, and, most importantly of all, the warrior monks of the Teutonic Order, they sought to expand Christendom through conquest and conversion. In the process they forged a new world with a profound legacy that resonates into the present.
Aleksander Pluskowski traces the broader story of the Baltic Crusades. Pluskowski explores how the construction of castles and towns, and the introduction of new languages, technology, monetary economies, and religion transformed the conquered societies. Moving through the years, we see how the history of the crusades was reinvented in the twentieth century to serve nationalist aims, including those of the Third Reich. This is a fascinating study that provides a fresh look at the impact of centuries of religious warfare across northern Europe.

This should have been right up my alley but I found this book to be a disjointed slog - clear the author is an archeologist, not a historian, and not necessarily a compelling writer either. Tons of in depth scholarship here but so much felt like a dumping of facts and details - no sense of the narrative or life or impact or the northern crusades in general. The final section, connecting it to recent history, I also didn’t find landed particularly well.
Was very excited to read this but this was not for me, and is not for general audiences. This is a purely academic book.

I feel like I'm being harsh here but 3.5/5 rounding down for Goodreads. Two caveats - (1) Medieval Eastern Europe is something I've read very little on (this is my first read about the Baltic Crusades) and (2) I paid full hardcover price (this is a very recent release) and I'm a bit annoyed I didn't enjoy the book that much.
Basically it's an in-depth history of the Baltic Crusades and Catholic vs Pagan warfare starting in the 770s with the Frankish conquest of the Saxons. There's a mix of political and military history (the wars, diplomacy etc) and the broader social cultural history (the German settlement of the Baltic and the economic changes it brought as well as the relations between the settlers and the natives). It's easier to describe my feelings on the book by splitting it into strengths and weaknesses:
Strengths: It's very detailed and well researched, the notes and bibliography at the end are quite long and have loads of things in different languages. Pluskowski clearly knows what he's talking about. When he's talking in broad strokes the book is quite good. I enjoyed the sections on trade, settlement and conversion. There's an interesting chapter later on about the survival of pagan practices and how they combined with Christian beliefs, especially in the countryside. I also liked the chapter on warfare in Lithuania during the 14th century, as it was done in broad detail and talked about how knights from all over Europe (especially England and France during the breaks in the Hundred Years War) would come to the Lithuanian frontier.
Negatives - The reason for only giving it 3.5/5 (and 3 stars on Goodreads) is that a lot of the book felt like a slog. A lot of the book felt like lists of various lords invading a place and bishops establishing random dioceses. There was quite a few times I felt myself skipping words and just glancing at the page to see if there was anything important. The last 2 chapters about the longterm legacy of the Baltic Crusades and how each ethnic and national group's academics and political leaders in the 19th and 20th centuries tried to claim the symbolism of the conflict for their own goals was particularly bad for me. I really felt like I was forcing myself to finish the book just to get it over with.
The reviews on the cover by academics and historians who know way more than me say that this is probably going to be considered the new standard work on the subject in English. Despite my problem with the book that is probably true. It's up to date, there's not a lot of other options in English, and it's not stupidly expensive like the specialist books. So if you are specifically interested in learning about the Baltic Crusades it might be worth a read, but if like me you prefer to jump between topics I'd say skip it

The Black Cross, by Professor Aleks Pluskowski is a major work of non-fiction, being a comprehensive history of the Baltic Crusades.
Throughout much of the English-speaking world, the term "Crusade" is identified with events in the Middle-East, largely focused on attempts to control Jerusalem, however there were crusades in other areas, such as those targeting people perceived as heretics in southern France.
The Baltic Crusades took place across Northern Europe from the 11th to the 15th century, and it could be argued that they have never fully received the attention they deserved, not least because of the lasting impact which they have had on the subsequent history of the nation states involved. Their legacy today can be clearly seen in tangible areas such as religion, political boundaries and, of course, the splendid castles documented by Professor Pluskowski. There are lasting effects which are less obvious but equally important. From the Hanseatic League to the Third Reich, and the Cold War the politics, economics and mentalities of northern and Eastern Europe have been shaped by the actions of those who led the Baltic Crusades.
Professor Pluskowski's new work deserves to be seen as a major scholarly advance in this field.

This review commends The Black Cross as a comprehensive and engaging study of the Baltic Crusades. It highlights Pluskowski’s balanced approach – blending archaeological evidence with chronicles to show how Teutonic knights, merchants, settlers and pagan communities interacted. The review concludes that the book illuminates the profound impact of these “holy wars” on northern Europe’s history, making The Black Cross essential reading for medieval history fans.
