Prussian royalty, the last Grand Master of the Teutonic Knights, who after converting to Lutheranism, became the first monarch of the Duchy of Prussia, the secularized state that emerged from the former Monastic State of the Teutonic Knights.
Albert was the first European ruler to establish Protestantism as the official state religion of his lands. He proved instrumental in the political spread of Protestantism in its early stage, ruling the Prussian lands for nearly six decades (1510–1568).
Albert was the third son of Frederick I, Margrave of Brandenburg-Ansbach. His mother was Sophia, daughter of Casimir IV Jagiellon, Grand Duke of Lithuania and King of Poland, and his wife Elisabeth of Austria.
Albert married first, to Princess Dorothea (1 August 1504 - 11 April 1547), daughter of King Frederick I of Denmark, in 1526. They had six children. He married secondly to Anna Maria (1532–20 March 1568), daughter of Eric I, Duke of Brunswick-Lüneburg, in 1550. The couple had two children.
He died at Tapiau (now Gvardeysk, Russia) on 20 March 1568.
