The Union of Lublin 1569: Poland and Lithuania Join

In 1569, the Polish-Lithuanian Commonwealth was born at the Union of Lublin, creating one of the largest and most unusual states in early modern Europe. This episode explores the negotiations between King Zygmunt II August and the Lithuanian nobility, the fierce debates over territory and sovereignty, and the final Act of Union that merged two realms into a single Commonwealth with a shared monarch, parliament, and currency—but separate laws, armies, and treasuries. We trace the path from the personal union first forged at Krewo in 1385 through long centuries of cooperation and conflict, leading to the pivotal moment when Lithuania's need for military aid against Muscovy forced their hand. Along the way, we meet key figures like the Polish king Zygmunt II August and the Lithuanian magnate Mikołaj "the Black" Radziwiłł, and we examine the cultural and political forces that made the Union possible. The episode also touches on the controversial incorporation of Podlasie, Volhynia, and Kyiv into the Kingdom of Poland—a move that provoked Lithuanian outrage but ultimately secured the Union's passage. This is the story of how two proud nations chose to stand together, shaping the fate of Eastern Europe for centuries to come. #UnionOfLublin #PolishLithuanianCommonwealth #ZygmuntIIAugust #MikolajRadziwill #Podlasie #Volhynia #Kyiv #Sejm #Lublin #Krewo #UniaLubelska #EasternEurope #16thCentury #JagiellonianDynasty #Muscovy #History #FexingoHistory #EarlyModern Keep every episode free: buymeacoffee.com/fexingo
