Mazovia (with Warsaw) Joins Poland

From Poland: The First Thousand Years, by Patrice M. Dabrowski (Cornell University Press, 2014), Kindle pp. 146-149:

Zygmunt’s reign did bring many positive developments, however. One important accomplishment was the ultimate incorporation of Mazovia (with its ducal capital of Warsaw) into the Crown of Poland. Regardless how odd this may seem to contemporary readers, Warsaw—despite its central location and later claims to fame—was not yet fully a part of the realm. Since the fourteenth century, Mazovia had been a fief of Poland, controlled by a branch of the old Piast princely dynasty. Bit by bit, the Crown of Poland had acquired pieces of that territory; yet it was only after the death of the last Mazovian prince, Janusz III, in 1526 that the process of incorporation was completed.

For a Polish province, Mazovia was in many ways atypical. The duchy had long eschewed battle with the Teutonic Knights to its immediate north and even maintained good trade relations with them. As of the late fourteenth century, Mazovians had played an important role in facilitating the trade of timber and naval stores coming to Baltic ports via the Narew, Bug, and Vistula Rivers. The duchy likewise assisted the transit trade of furs, wax, and honey from Lithuania as well as cattle from Volhynia. After 1500, Mazovians expanded their activities to include the grain trade. As for the social composition of the duchy, it boasted a preponderance of nobles—certainly vis-à-vis Poland-Lithuania as a whole. Some 20 percent of the population claimed a noble patent—quite a large number, though to be sure most of these were impoverished soldier-nobles. Warsaw had a provincial feel, although in the sixteenth century it was beginning its ascent, in part thanks to trade.

Although King Zygmunt managed to incorporate the remaining pieces of Mazovia into the Crown, he was less successful in pressing state and dynastic interests in the region of the Baltic Sea, this despite a very real occasion to do so. For a war fought against the Teutonic Order in 1519–1521 brought the Knights to their knees—literally. One of the most famous images in Polish history dates from 1525, the so-called Prussian Homage. A triumphant view of this grand event was painted in 1882 by the nineteenth-century Polish artist Jan Matejko, whose colorful brushstrokes lavishly rendered the scene of the former grand master of the Teutonic Knights, Albrecht von Hohenzollern, kneeling before the Polish king and publicly swearing his fealty.

Yet such a rosy view of the event—although attractive to Matejko’s contemporaries, who took especial pleasure in seeing Prussians bowing down before the Poles, even if only in the deep historical past—was misleading. Much more could have been achieved than simply having Albrecht von Hohenzollern kneel before the Polish king (who was, after all, his uncle) and resign himself to the status of subordinate. What could have marked the end of Prussia as an independent entity—had Zygmunt pursued the fight further—instead gave little Prussia a new lease on life. Recall that part of Prussia had already been incorporated into the Crown by Zygmunt’s father. This was the so-called Royal Prussia, which had sought to break away from the hold of the Teutonic Knights and turned to the Polish king for help.

What went wrong, then? Although it was a Polish fief, in this moment Prussia was permitted to undergo a notable change. No longer to be run by the Teutonic Knights, it was transformed by Albrecht von Hohenzollern-Ansbach (the aforementioned nephew of Zygmunt) into a secular state. Henceforth the last grand master of the Teutonic Order would be known as Duke of Prussia, and his successors would have hereditary rights in the lands formerly held by the Order. Not only that: the Prussia of Albrecht von Hohenzollern simultaneously embraced the views promulgated by Martin Luther, who by nailing his ninety-five theses to the door of a church in Wittenberg in 1517 initiated a movement that would forever change the face of Christian Europe. This was the Protestant Reformation. Close to Martin Luther himself, Albrecht became—with Zygmunt’s permission—the first territorial Lutheran ruler and Prussia became the first Protestant state in Europe.

That this should occur without bloodshed or upheaval was in part due to Zygmunt the Old’s willingness to approve this amazing transformation of the former arch-Catholic polity—in part to keep Ducal Prussia from moving into the orbit of the Holy Roman Empire. To be sure, in the Treaty of Kraków of 1525—the first European treaty between a Catholic and a Protestant state—Zygmunt and Albrecht agreed that Ducal Prussia would come fully under Polish control on the extinction of Albrecht of Hohenzollern’s line. That only a generation later a different king would, in a pinch, exchange his hereditary rights to succession for military assistance is but one of the fateful missteps that would haunt Polish history for centuries to come, even if it could not be foreseen in 1525.
