John, nicknamed the Alchemist (German: Johann der Alchimist; 1406 – 16 November 1464) was a Margrave of Brandenburg-Kulmbach and served as the peace-loving Margrave of Brandenburg after the abdication of his father, Frederick I, the first member of the House of Hohenzollern to rule Brandenburg.
John was the eldest son of Frederick I, Margrave of Brandenburg (1371–1440) and Elisabeth of Bavaria-Landshut (1383–1442), daughter of Frederick, Duke of Bavaria, and his second wife Maddalena Visconti.
After marrying Barbara of Saxe-Wittenberg (1405–1465), daughter of Rudolf III, Duke of Saxe-Wittenberg, John hoped to eventually succeed to Saxe-Wittenberg once its line of Ascanian dukes died out. When this happened in November 1422, however, Emperor Sigismund was on poorer terms with the Hohenzollerns and was only willing to compensate John with a money payment.
John began participating in governmental affairs in Brandenburg in 1424. Frustrated by disputes with the feudal nobility, Frederick I retired to his castle at Cadolzburg in Franconia in 1425, granting the regency of Brandenburg to John at a Landtag in Rathenow on January 13, 1426, while retaining the electoral dignity for himself.
