ALBERT (1522-1557), prince of Bayreuth, surnamed THE WARLIKE, and also ALCIBIADES, was a member of the Franconian branch of the Hohenzollern family. His restless and turbulent nature marked him out for a military career; and having collected a small band of soldiers, he assisted the emperor Charles V. in his war with France in 1543. Sharing in the attack on the Saxon electorate, Albert was taken prisoner at Rochlitz in March 1547 by John Frederick, elector of Saxony, but was released as a result of the emperor's victory at Muhlberg in the succeeding April. He then followed the fortunes of his friend Maurice, the new elector of Saxony, deserted Charles, and joined the league which pro posed to overthrow the emperor by an alliance with Henry II. of France. Having extorted a large sum of money from the burghers of Nuremberg, he quarrelled with his supporter, the French king, and offered his services to the emperor. Charles, anxious to secure such a famous fighter, gladly assented to Al bert's demands and gave the imperial sanction to his possession of the lands taken from the bishops of Wurzburg and Bamberg. After Albert had been placed under the imperial ban in Dec. on account of his depredations in Franconia, he was defeated by Henry II., duke of Brunswick, and compelled to fly to France. He there entered the service of Henry II., and had undertaken a campaign to regain his lands when he died at Pforzheim Jan. 8, See J.
