Eric I, Duke of Schleswig
Eric I Abelsøn (Danish: Erik 1. Abelsøn af Danmark) (died 27 May 1272) was a Danish nobleman. He was the ruling Duke of Schleswig from 1260 until his death in 1272. He was the second son of King Abel of Denmark, Duke of Schleswig and Mechtild of Holstein.
After the death of his elder brother Duke Valdemar III in 1257, Eric inherited the claim to the Duchy of Schleswig. However, his uncle and potential feudal overlord King Christopher I of Denmark refused to install him as duke.
Subsequently, Eric participated in the coalition of Bishop Peder Bang of Roskilde and Prince Jaromar II of Rugia against King Christopher. He took part in the military campaign of 1259 which resulted in the conquest of Copenhagen.
Duke of SchleswigEdit
After the death of Christopher in 1259, he was created Duke of Schleswig by the new king Eric V in 1260.
Already the following year, fighting with the king broke out anew. The Queen Dowager, Margaret Sambiria, acting as regent for her under age son, feared aggression from the Duke. However, Duke Eric was able to defeat the royal army at the Battle of Lohede and capture the young King Eric and his mother. As a result, he was able to obtain huge advantages for his duchy at the subsequent treaty in 1264.
Duke Eric died 27 May 1272.
