[edit] Biography

Frederick entered early into the service of Austria and fought on the side of King Sigismund of Hungary. After he returned he divided the inheritance from his father with his brother John, who received Bayreuth while Frederick kept Ansbach. At first he tried to mediate in the imperial confusion between King Wenceslaus and the party of Rupert of the Palatinate, nevertheless he fought on the side of Rupert in September 1399.

He resumed his rule of Ansbach in 1409 and after heavy feuding entered into the service of King Sigismund. As a representative of Brandenburg he took part on 20 September 1410 in the election of Sigismund as Holy Roman Emperor in Frankfurt. In gratitude, King Sigismund made him Oberster Hauptmann and Verwalter der Marken (1411). With an iron hand Frederick fought against the rebellious nobility of the March of Brandenburg (in particular, the Quitzow family) and, in the end, restored security. Frederick also became a member of the Parakeet Society and of the League of Constance.

At the Council of Constance (30 April 1415) Sigismund granted Frederick the titles of Margrave and Prince-elector of Brandenburg. On 21 October 1415 the Brandenburg states meeting in a Landtag asked him to rule in Berlin. The king awarded him the formal enfeoffment of the margravate on 18 April 1417. As Frederick did not agree with the forcible action of Sigismund against the Hussites, relations between them cooled.

Constant feuding with the nobility of Brandenburg led Frederick to withdraw to his castle at Cadolzburg in 1425 and transferred the regency of the margravate to his son John in 1426 (Frederick, however, remained elector). After 1427 he organized the imperial war against the Hussites and helped on the occasion of the Council of Basel substantially in the mediation by the Prager Kompaktaten (30 November 1433).

Upon his death in 1440, Frederick was succeeded as Elector by his second-eldest son, Frederick II.
