Eric II the Memorable (c. 1090 – 18 September 1137) was king of Denmark between 1134 and 1137. Eric was an illegitimate son of Eric I of Denmark, who ruled Denmark from 1095 to 1103. Eric the Memorable rebelled against his uncle Niels of Denmark, and was declared king in 1134. He punished his adversaries severely, and rewarded his supporters handsomely. He was killed by a subject in 1137 and was promptly succeeded by his nephew Eric III of Denmark.
