Constant feuding with the nobility of Brandenburg led Frederick to withdraw to his castle at Cadolzburg in 1425 and transfer the regency of the mark to his son John in 1426 (Frederick, however, remained elector). After 1427 he organized the imperial war against the Hussites. He is best known for joining the papal legate Julian Cesarini in August 1431 to attack the Hussites in the disastrous Battle of Domažlice. He subsequently provided substantial assistance in the mediation of the Compacta of Prague at the Council of Basel (30 November 1433).
