EDGAR or EADGAR (c. 1130), called the Aethel ing, was the son of Edward (the exile), a son of the English king Edmund Ironside, by his wife Agatha, a kinswoman of the em peror Henry II., and was born probably in Hungary some time before 1057, the year of his father's death. After the death of Harold in 1066, Eadwine and Morkere desired to make him king, but on the advance of William I., Edgar and his supporters made their submission. He took part in two unsuccessful risings in the north (1o68 and 1069), afterwards taking refuge in Scotland, where his sister Margaret married the Scottish king, Malcolm Canmore. In 1074 he went to Normandy and made peace with William. In 1097 he made a successful attempt to set his nephew Edgar on the throne of Scotland, and in 1099 went to the crusade. He returned to England in Henry I.'s reign, but sided with Robert of Normandy against the king in their last war, and was taken prisoner at the battle of Tinchebrai in '106. He was soon released, and lived in obscurity until his death, the date of which is uncertain.
