Thomas Carlyle wrote that he might have been in the real Waldemar's employ, where he could have learned his master's manners.
He posed as a representative of the ancestral Ascanian princely house, which he promised to help against the foreign and unpopular Bavaria.
Emperor Charles IV, on the defensive, invested the Wrong Waldemar on 2 October 1348 with the Margraviate of Brandenburg.
Only a few towns held on to the Wittelsbach, including Treuenbrietzen, which during this period gained its prefix treu- meaning 'faithful'.
Thomas Carlyle in his History of Friedrich II of Prussia called False Waldemar "the wickedest and worst trouble of their [Ascanian] raising",[1] "a new goblin, where already there were plenty, in the dance round poor Ludwig [Louis the Bavarian]".
