The siege of Schleswig took place from 1131–1132 during the Danish Civil Wars. It saw forces under the Eric II of Denmark, Holy Roman Emperor Lothair III, and Adolf of Holstein face off against Niels I of Denmark and his son Magnus the Strong of Götaland. Eric failed to break the siege, as he was deserted by Lothair III after he came to an agreement with Magnus and Niels. Only Adolf of Holstein remained with Eric, but his forces were destroyed trying to cross the Eider.
