100 books like Northern Crusades, the Baltic and the Catholic Frontier, 1100-1525

This is a provocative book. Its very title suggests how difficult it is to understand Polish history than other that a divine joke. Yet his scholarship is excellent and his insights enlightening.

This is especially true for the first volume, which deals with the emergence of the Polish kingdom from rude barbarism to a political and cultural force so powerful that, after its union with Lithuania, dominated East Central Europe for generations. The total collapse of the kingdom in the 18th century—largely to defects in the constitution that allowed foreign interference in the election of the king—has blinded us to what Poland achieved in those forgotten centuries.

The history of the Baltic Crusade cannot be understood in isolation from the Polish kingdom. This is the era when Poland recovers from the disasters begun by the Mongol invasions of the 1240s and begins its own eastward expansion.

As the title indicates, this is really the story of Casimir III, whose father arranged a Lithuanian marriage that brought peace on the eastern frontiers and later allowed him to expand toward Rus’ (especially Ukraine) when the minor states there collapsed. Casimir succeeded in everything except siring a legitimate male heir, even though that was the one task expected of every monarch in this era. He did leave behind a flourishing state, a powerful church, and a national goal of driving back those Germans (especially the Teutonic Knights) who had made great inroads into areas claimed as the national patrimony.

The Germans and Poles moved into a land inhabited by flourishing native tribes that have previously been understood only through the observations of German and Polish chroniclers.

Pluskowski shows that the native peoples had a sophisticated local economy that was hardly changed by the German conquerors. That is, wherever the Teutonic Order and its associated bishops and abbots brought in German or Dutch colonists, the farming practices reflected those of the immigrants’ homelands; however, the three-field system required farmers to work together, while the original inhabitants preferred to retain individual farms worked on the two-field system. The three-field system produced more food, but the Native Prussians valued their freedom more.

This is a very detailed study, with abundant information on what people ate, how they lived, and how they were buried.

This is a look at the evolving Lithuanian state at a key moment in its efforts to fight off western crusaders, expand to the east against Russians and south against Mongols, and accommodate its society and religious practices to its allies and subject peoples.

This was the era when the modern states of Belarus and Ukraine were forming under Lithuanian rule or protection. The cities of those regions, as well as the princes, were all Orthodox Christians, but they preferred being governed by tolerant pagans who lived among them than being heavily taxed by Muslim nomads who despised them.

In the decades to follow, Lithuanians would be deeply influenced by Polish culture and religious thought, so the conversion to Roman Catholicism in 1387 came as no surprise.

When we say the word Crusades, most of us think of Jerusalem, and the many Christian efforts to wrest control of what was called the Holy Land from Islamic control -- six separate expeditions from 1095-1291. The foundation of Prussia is found in the lesser-known, but equally sanguinary campaigns of conquest undertaken by a religious order of Germanic origin, the Teutonic Knights. Their aim was to wrest lands along the Baltic Sea, east of the Oder, Vistula, and Nieman Rivers, from non-Christian Slavic tribes, a process that surged back and forth for over four centuries, until the Order was secularized in 1525 by its last grandmaster, a Hohenzollern. Christiansen's impressive, chronological narrative gives a comprehensive overview, and has the additional quality of being very well written. The Teutonic Order is the foundation story of Prussia, along with the emergence of the Hohenzollern dynasty.

A solid grasp of crusading geography is essential for anyone who wishes to understand these complex holy wars, and this book is unsurpassed in providing such information in a clear and comprehensible manner. Its many maps and charts, each beautifully drawn and accompanied by insightful commentary and, in most cases, relevant illustrations and excerpts from primary sources, make this an indispensable resource that belongs in every crusade historian’s library. If you can find a used copy of this out-of-print treasure, buy it without hesitation. Be careful, there is another so-called atlas of the crusades out there by someone who is not a crusade historian, and it is filled with numerous errors.   

A classic. Originally published in 1956, it was one of the first retorts to the dominant strain of military history that emphasized decisive battle, as seen through the eyes of 19th-century theory. Instead, Smail advances the notion—now widely held—that medieval warfare deemphasized risky battles and instead utilized a range of effective operational approaches (raiding, ravaging, sieging, and skirmishing) in a coherent, positional fashion. Similarly in opposition to older approaches, Smail examines not only western warfare through the activities of crusader and crusader-state armies but also how Muslim forces were organized, sustained, and fought. While his sections on military organization, fortifications, and technology have been greatly updated by newer studies, this remains a standard text for anyone interested in the general subject.

A great insight informs every aspect of this excellent book. While few historians today would put the crusades down to mere fanaticism, too many uninformed people still think of the crusades in absurdly simplistic terms of clashing civilizations, cultures, and religions. This book takes aim at that sort of ignorance by telling the history of one of the world’s great historical phenomena in a very accessible way from the perspective with which most readers will be least familiar.

I stumbled on this book in Raven secondhand bookstore in Cambridge, Massachusetts.

I was researching for my 12th-century trilogy, Conquest, and this book is a brilliant critical study of the Anglo-Norman chronicler, Orderic Vitalis. The book is wonderfully written and conveys the astonishing beauty of Orderic’s own work.

Orderic, as he writes, ranged far and wide across the Anglo-Norman kingdom in his imagination and then returned to his ‘black-clad life’ as a monk.

Raven and Shakespeare and Co. Bookshop in Paris are amongst my top favourites. I love to visit Shakespeare for its cramped unevenly floored labyrinth and intelligent array of books.

I greatly enjoy a bookshop – these two and Victoria Bookshop in Haverfordwest spring to mind – where the staff is obviously as lovestruck by books as I am.

There are numerous excellent books of every length (one runs more than 900 pages) that survey the crusades across the centuries and in their multiple theaters of operation. And several books are more recent, but this little book of fewer than two hundred pages is a gem. Written in clear prose and incorporating biographies of important individuals, key documents, and a glossary, it is tailor-made for students and general readers, and its price is modest.
