Reichsacht
After in 1541 the ambitious Margrave Albert Alcibiades assumed the rule over Kulmbach-Bayreuth, he barged onto the battlegrounds of the Schmalkaldic War, several times switching sides between Emperor Charles V and the Lutheran princes of the Schmalkaldic League. In 1552 he sparked the Second Margrave War against Nuremberg and the neighbouring Prince-bishoprics of Würzburg and Bamberg. His soaring plans to re-establish the medieval Duchy of Franconia under his rule ended with his utter defeat and an Imperial ban in 1554.
