Excerpt: Adolphus XI of Schauenburg (Low German: , German: , Danish: ) (1401 - 4 December 1459), as Adolph I Duke of Schleswig (Danish, Sonderjylland, i.e. Slesvig), and as Adolph VIII Count of Holstein-Rendsburg, was the mightiest vassal of the Danish realm. Adolph descended from a branch of the House of Schauenburg, who had for centuries been counts of Holstein, and as such, vassals of the Holy Roman Empire. His great-grandfather Gerhard the Great, having also been a Regent of the Kingdom of Denmark, had received the Duchy of Sonderjylland from the Danish crown as a hereditary fief. It had been lost for the Schauenburgs between 1330 and 1375, with Queen Margaret I of Denmark restricting the regained ducal power in 1386, and again from 1414 to 1440. Count Adolph's parents were Gerhard VI, Count of Holstein-Rendsburg and Catherine Elisabeth of Brunswick-Luneburg. Adolph was only three years old when his father was killed in action against the Ditmarsians in the Battle at Hamme near Heide (today's Schleswig-Holstein), on 4 August 1404. Adolph was educated at the court of Frederick I, Margrave of Brandenburg at Hohenzollern Castle. Adolph's elder brother Henry IV succeeded their father. As Duke of Schleswig, he was under the tutelage of the Danish crown due to his minority until 1414. However, then the crown denied Henry's claim to dukedom. Henry and his mother and brothers stood together and fought for his claim. Henry was killed in action beleaguering Flensburg on 28 May 1427. Adolph and his younger brother Gerhard VII then succeeded Henry as Counts of Holstein-Rendsburg, continuing their efforts to receive the Duchy of Schleswig. However, Gerhard died in 1433 in Emmerich upon Rhine. In July 1435 Adolph and the Danish King Eric of Pomerania concluded the second Treaty of Vordingborg at Vordingborg Castle, confirming Adolph's de facto holdings in Schleswig duchy. In 1439, the new Danish King Christopher III acquired the loyalty of Adolph by granting him the entire Duchy of Sc
