The best books on medieval Baltic history

This wide-ranging, erudite, and witty account remains the most enjoyable survey of the era. His explanations of complex ideas and events cut through many of the difficulties involved in understanding a very different time and different places than our own. I especiallly liked the way he could  tie the crusades in the Baltic to what was happening elsewhere in Europe and in the Holy Land, and to show how contemporaries wrestled with difficult, even contradictory, ideas.

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.
