WGurre Castle was a royal castle situated in North Zealand, Denmark. Its ruins lie on the outskirts of Helsingør, close to the town of Tikøb on lake Gurre Sø at Gurre. The ruins have been excavated and are now restored.
WHelvig of Schleswig was the queen of Denmark as the spouse of King Valdemar IV. She was the mother of Queen Margaret I of Denmark.
WMargaret I was the queen who founded the Kalmar Union of the kingdoms of Denmark, Norway, and Sweden, spanning Scandinavia for over a century. Margaret was known as a wise, energetic and capable leader, who governed with "farsighted tact and caution," earning the nickname "Semiramis of the North". She was derisively called "King Breechless", one of several derogatory nicknames invented by her rival Albert of Mecklenburg, but was also known by her subjects as "the Lady King", which became widely used in recognition of her capabilities. Knut Gjerset calls her "the first great ruling queen in European history."
