Prussian Tribut
During the
Reformation endemic religious upheavals and wars occurred, and in
1525, the last Grand Master of the
Teutonic Knights,
Albert of Prussia, a member of a cadet branch of the house of
Hohenzollern, resigned his position, became a
Protestant and received the title "
Duke of Prussia" from
Sigismund I King of Poland, Great Duke of Lithuania and imperial duke of Silesia in the act called
Prussian Tribut. In a deal partially brokered by
Martin Luther (under imperial
ban since
1521), Ducal Prussia became the first
Protestant state, along the lines of the later religious
Peace of Augsburg.
