Albert II was the margrave of Brandenburg-Kulmbach (Brandenburg-Bayreuth) from 1527 to 1553. He was a member of the Franconian branch of the House of Hohenzollern. Because of his bellicose nature, Albert was given the cognomen Bellator during his lifetime. Posthumously, he became known as Alcibiades.

The Principality of Bayreuth or Margraviate of Brandenburg-Bayreuth was an immediate territory of the Holy Roman Empire, ruled by a Franconian branch of the Hohenzollern dynasty. Since Burgrave Frederick VI of Nuremberg was enfeoffed with the Margraviate of Brandenburg in 1415/17, the Hohenzollern princes transferred the margravial title to their Franconian possessions, though the principality never had been a march. Until 1604 they used Plassenburg Castle in Kulmbach as their residence, hence their territory was officially called the Principality of Kulmbach or Margraviate of Brandenburg-Kulmbach until the Empire's dissolution in 1806.
