Indeed, the entire coastal region of Pomerania, Warmia, and Mazury is an integral part of modern Polish national identity. But prior to the mid-20th century, this region had a remarkably fluid and varied history, to which the Polish people and state was only one of many crucial contributors.
The traditional geographical coastal regions of Pomerania and Prussia, together extending from modern north-central Germany through Poland and the Kaliningrad Oblast to the southern coast of Lithuania, have been at the center of some of the most significant historical moments and events of the last millennium. During the last two centuries, their centrality to world history has been especially grave. Their role in the Partitions of Poland, German Unification, and both World Wars was practically paramount.Polish people, institutions, and states have been integral to that entire history. But throughout the last millennium, they have never been alone there, and only rarely have they been dominant. Rather the region also has been shaped by people, institutions, and states identifying alternately as Pomeranian, Prussian, German, Lithuanian, Dutch, Swedish, and Russian, among others. Indeed, the modern subregions of Pomerania, Kuyavia, Warmia, Mazury, and Kaliningrad have been – for all intents and purposes – at various times Pomeranian, Prussian, Polish, German, Prussian (again, albeit quite different), and Russian.
