Königsberg (now Kaliningrad), the most easterly city in the Prussian Empire, was a prominent cultural and economic hub in the eighteenth century. Its position as a Hanseatic League port, accessible during the winter from the Baltic Sea, had attracted significant trade and wealth particularly since the early modern period. Königsberg's original multi-ethnic population, consisting of Latvians, Lithuanians/Livonians, Polish, Old Prussians (Prußen), and Jews were joined by Scottish Presbyterians, Dutch Remonstrants, and Huguenots in the seventeenth century, as well as merchants and tradesmen. The plague of 1709–10 in East Prussia decimated the population, particularly Old Prussians. However, Elector Friedrich Wilhelm's drastic repopulation programme of East Prussia settled Swiss, Dutch, French, and Bohemian immigrants, as well as immigrants from the Palatinate, the Rhineland, Franconia, Swabia, and Nassau, making the province ethnically diverse yet disjointed. Magdalena Niedzielska highlights the different facets of patriotism in the period and region, which were divided between allegiance to the Prussian monarchy [Staatspatriotismus], regional patriotism (Warmia, Lithuania Minor), and the historical loyalties of the Old Prussians.
Königsberg was strategically placed between Berlin, St Petersburg, Riga, Reval, and the Duchy of Courland. The home of a prominent Protestant university, the Albertina, founded in 1544, it attracted scholars, students, and, in the eighteenth century, a vibrant publishing industry that produced the works of Kant, Herder Johann Georg Hamann (1730–88), and Theodor Gottlieb von Hippel (1741–96). Indeed, as Kant's biographer suggests, Königsberg was much more cosmopolitan than Berlin at the time.
