Diorama of the siege of Kulmbach 1553. The battle is recreated in the German Tin Soldiers Museum in Kulmbach. Margrave Albrecht Alcibiades of Brandenburg-Kulmbach (1522-57) had tried to create a Franconian dukedom for himself at the expense of the Franconian prince-bishoprics Würzburg, Bamberg, Eichstätt and the imperial cities Schweinfurt and the rich and powerful Nuremberg. This meant war.
The prince-bishops and Nuremberg allied with the prince elector of Saxony and the duke of Braunschweig and fought against the margrave.
1553 the allied armies could enclose Kulmbach, the residence town of Albrecht Alcibiades and conquer the city. Kulmbach was completely destroyed, all male citizens killed, only the mighty Plassenburg could withstand for another eight months, but then had to capitulate too.
