Hans Ulrik Gyldenløve (10 March 1615 – 31 January 1645) was the illegitimate son of King Christian IV of Denmark and his mistress, Karen Andersdatter. He was also a Danish-Norwegian Navy officer and lensmann bailiff. Childhood Hans Ulrik was born at the Kronborg castle in Helsingør, Denmark, on 10 March 1615. He was given Gyldenløve [Golden Lion] as his surname by his father. It was the traditional surname for the illegitimate children of the kings of Denmark–Norway in the 17th century. The King also appointed Ernst Normand as the guardian of his son. Hans Ulrik was educated, along with his older half-brother Christian Ulrik, with Jens Dinesen Jersin as their teacher and, for a time, in Sorø in Zealand, Denmark. In 1629 Hans went with another half-brother, Duke Frederik, the future King Frederick III of Denmark, to France. He was also given the royal estate of Vindinge (now Fuirendal, not far from Sorø) in Zealand. Career While the King was making a courtier and diplomat out of Christian Ulrik, he thought that the future for his other son would be in the Royal Navy. So Hans Ulrik was sent in 1634 to Karen Andersdatter's brother-in-law in Copenhagen, Laurits Andersen Hammer, the grocer, for his apprenticeship in the shipping yards. In 1635 he was made a Hofjunker [Gentleman of the Court]. In 1636, he was sent on one ship to Ireland and another ship to the Weser River in Germany. When he came back, he was appointed to the Kammerjunker [Gentleman of the Chambers]. Hans lived at the Frederiksborg until 1640, when its elderly commander died, and he had to move out. On his way to the Kronborg, he visited numerous inns and brothels, where he virtually “robbed” them of women, food and drink. Ten days later, his father received from a certain innkeeper a bill totaling almost two thousand rigsdaler, which had not been paid by Hans. In 1640, Hans Ulrik became an unteradmiral (Rear admiral) aboard the ship “Norske Løve” [Norwegian Lion]. He was given the order to bring the Danish Ambassador, Hannibal Sehested, aboard the “Norske Løve” to Spain. When they arrived in Spain, Hans Ulrik was supposed to immediately return to Denmark and resume his studies. But he was never serious about them. Dr. Otto Sperling, the physician who was on that trip to Spain, wrote that Hans Ulrik had “intet Hoved eller Ingenium derail” [neither the
