Eric II of Schleswig

Eric II Valdemarsen (c. 1288–1325) was Duke of Schleswig from 1312 until his death, the only legitimate son of Duke Valdemar IV. He already ruled jointly with his father before succeeding him, and in 1313 he married Adelaide of Holstein-Rendsburg.

Their son Valdemar was underage when Eric died in 1325, later ruling Schleswig and serving as king of Denmark in 1326–1329; their daughter Helvig married King Valdemar IV. Eric was buried in Schleswig Cathedral.
