Bogislaw IV, Duke of Pomerania

Bogislaw IV (died 19 February 1309 or 24 February 1309), of the Griffins dynasty, was Duke of Pomerania for thirty years. Bogislaw was the eldest son of Duke Barnim I by his second wife, sometimes said to be a daughter of King Eric X of Sweden. He was an adult at his father's death in 1278, having been co-ruler since 1276. His half-brothers Barnim II and Otto I were still very young and so he was sole ruler in Pomerania during their minority.
