inherited the claims upon Hungary and Bohemia of her mother, a granddaughter of Emperor Sigismund. The attempt to secure these thrones for the Hohenzollerns through this marriage failed, and a similar fate befell Albrecht's efforts to revive in his own favour the disused title of duke of Franconia. The sharp dissensions which existed among the princes over the question of reform culminated in the Bavarian War from 1459 to 1463, when Albrecht was confronted with a league under the leadership of Elector Palatine Frederick I and his Wittelsbach cousin Duke Louis IX of Bavaria-Landshut. Though defeated in the struggle, Albrecht continued fighting against Prince-bishop Rudolf II of Würzburg and even forged an alliance with his former enemy, the Bohemian king George of Poděbrady, a step which caused Pope Paul II to place him under the ban. Albrecht permanently resided at Ansbach from 1460; he also inherited the Principality of Kulmbach upon the death of his brother John in 1464. Brandenburg elector In 1471, Albrecht became Elector of Brandenburg, owing to the abdication of his remaining brother, Elector Frederick II, the year before. Now sole ruler over the entire Hohenzollern estates, he was soon actively engaged in their administration. By the 1472 Treaty of Prenzlau he ended the War of the Succession of Stettin, bringing the Duchy of Pomerania also under his supremacy. Having established his right to levy a tonnage on wines in the mark, he issued in February 1473 the Dispositio Achillea, which decreed that the Margraviate of Brandenburg should descend in its entirety to the eldest son, while the younger sons should receive the Franconian possessions of the family. After treating in vain for a marriage between one of his sons and Princess Mary of Burgundy, daughter and heiress of Duke Charles the Bold, Albrecht handed over the government of Brandenburg to his eldest son John Cicero, and returned to his Franconian possessions. Albrecht's main attention afterwards was claimed by the business of the empire. Seriously ill, he took part in the imperial election of 1486 which selected Maximilian of Habsburg as King of the Romans at Frankfurt Cathedral. A few weeks later, in March, Albrecht died while still staying in Frankfurt; he was buried in the Heilsbronn Abbey church near Ansbach. He left a considerable amount of treasure. Family and children Albrecht was married twice. First, he married 12 November 1446 Margaret of Baden, daughter of Margrave
