Barnim XI (1501–1573; by some accounts Barnim IX), son ofBogislaw X, Duke of Pomerania, becameduke on his father's death in 1523.

Barnim ruled for a time in common with his elder brotherGeorge I; and after George's death in 1531 he shared the duchy with his nephewPhilip I, retaining for himself the duchy ofPomerania-Stettin.The earlier years of his rule were troubled by a quarrel with MargraveJoachim I Nestor of Brandenburg, who wished to annexPomerania. 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 ofMartin Luther, and joined theleague 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 emperorCharles V, to pay a heavy fine, and to accept theInterim, 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 FalkenreckFalke family.

In 1569, Barnim handed over his duchy to his grand-nephew,John Frederick, and died atStettin on 2 June 1573.^[2]
