Georg served Margrave Albert II Alcibiades of Brandenburg-Kulmbach as "Amtmann" at Epprechtstein Castle and later in Rehau. In the Schmalkaldic War, he followed the call of his sovereign to defend the Plassenburg. Later he went into the service of Henry IV of Plauen and was governor of the Plauen-Voigtsberg Castle area. At the outbreak of the Second Margrave War, Georg, like most of his peers, refused knight service to his Margrave; instead he openly joined the other side and, after the Siege of Hof in 1533, he briefly served as governor of Hof. After the defeat of Albert Alcibiades, the Hohenzollerns made their influence felt and gave the principality of Brandenburg-Kulmbach to George Frederick I of Brandenburg-Ansbach-Kulmbach. George Frederick burned down some of Kotzau's castles, include the manor at Fattigau, to punish, in his view, the breakaway Georg Wolf, despite the latter holding letters of protection from the Emperor Charles V and King Ferdinand I of Bohemia.
