Barnim XI (1501–1573; by some accounts Barnim IX), son of Bogislaw X, Duke of Pomerania, became duke on his father's death in 1523.
Barnim ruled for a time in common with his elder brother George I; and after George's death in 1531 he shared the duchy with his nephew Philip I, retaining for himself the duchy of Pomerania-Stettin.The earlier years of his rule were troubled by a quarrel with Margrave Joachim I Nestor of Brandenburg, who wished to annex Pomerania. In 1529, however, a treaty was made which freed Pomerania from the supremacy of Brandenburg on condition that if the ducal family became extinct the duchy should revert to Brandenburg. Barnim adopted the doctrines of Martin Luther, and joined the league of Schmalkalden, but took no part in the subsequent war.
But as this attitude left Barnim without supporters he was obliged to submit to the emperor Charles V, to pay a heavy fine, and to accept the Interim, issued from Augsburg in May 1548. Also Johann von Falcken[1] was appointed Chancellor because his ancient noble family was in close contact with Charles V. Johann v. Falcken was also based in Westphalen and married Elisabeth v. Reck upon which Charles V approved the merging of the two ancient noble names into Falkenreck Falke family.
In 1569, Barnim handed over his duchy to his grand-nephew, John Frederick, and died at Stettin on 2 June 1573.
Barnim married Anna of Brunswick-Lüneburg, a daughter of Duke Henry I of Lüneburg. The marriage produced the following children:
