Although most accounts of Polish history show the two centuries after the end of the Jagiellon Dynasty as a time of decline leading to foreign domination, Poland-Lithuania remained an influential player in European politics and a vital cultural entity through most of the period.

The Elective Monarchy

The death of Sigismund II Augustus in 1572 was followed by a three-year Interregnum during which adjustments were made in the constitutional system. The lower nobility was now included in the selection process, and the power of the monarch was further circumscribed in favor of the expanded noble class. From that point, the king was effectively a partner with the noble class and constantly supervised by a group of senators. Once the Jagiellons passed from the scene, the fragile equilibrium of the commonwealth government began to go awry. The constitutional reforms made the monarchy electoral in fact as well as name. As more and more power went to the noble electors, it also eroded from the government's center.

In its periodic opportunities to fill the throne, the szlachta exhibited a preference for foreign candidates who would not found another strong dynasty. This policy produced monarchs who were either totally ineffective or in constant debilitating conflict with the nobility. Furthermore, aside from notable exceptions such as the able Transylvanian Stefan Batory (1576-86), the kings of alien origin were inclined to subordinate the interests of the commonwealth to those of their own country and ruling house. This tendency was most obvious in the prolonged military adventures waged by Sigismund III Vasa (1587-1632) against Russia and his native Sweden. On occasion, these campaigns brought Poland near to conquest of Muscovy and the Baltic coast, but they compounded the military burden imposed by the ongoing rivalry with the Turks, and the Swedes and Russians extracted heavy repayment a few decades later.
