Albert of Brandenburg-Ansbach
First Duke of Prussia, born in 1490 in Ansbach, Bavaria; died in 1568 in Tapinu, East Prussia.
Elected grand-master of the Teutonic Order, 1510, he seized Church property to defray the expenses of a disastrous war with Poland (1519-1521).
He met Luther (1522-1523), on whose advice he secularized the order, and with the entire chapter and a majority of the knights adopted Lutheranism.
By the Treaty of Cracow in 1525, with Sigismund, King of Poland, the lands of the order became a fief of Poland vested in Albert, on whom Sigismund conferred the title of Duke of Prussia.
