Christopher I of Denmark
Christopher I (1219–1259), son of Valdemar II, was elected king after Abel's death and crowned at Lund in 1252. He enfeoffed Abel's son Valdemar as Duke of Schleswig in 1253, but his reign was spent fighting the Abel family, the Holsteiners and the Archbishop of Lund, Jacob Erlandsen, whom he seized and imprisoned in 1259.
After Jaromar II of Rügen invaded Zealand and took Copenhagen in 1259, Christopher died suddenly at Ribe, rumoured poisoned at mass. His son Eric V succeeded him.
