Eric Christoffersen of Denmark
"[1] Eric was the eldest son of King Christopher II and Euphemia of Pomerania.[2] In 1325, his father asked him to halt the Counts of Holstein and their allies, but was deserted by his troops, taken prisoner and confined in Haderslev Castle.His father was forced to abdicate and go into exile, while the 12-year-old Duke Valdemar of Southern Jutland was made king of Denmark under the regent, Count Gerhard III of Holstein.[3] After a period of chaos in the "magnates’ republic" of Denmark, King Christopher was restored as a puppet monarch in 1329 through the help of his half-brother Count John III.Eric was released in 1330, on the condition he married Elizabeth of Holstein-Rendsburg, dowager duchess of Saxe-Lauenburg and sister of his father's enemy, Count Gerhard III, by whom he had no children.
