Aethelred, or Ethelred, the Unready (c. 968-1016)From Chambers Dictionary of World History
King of England (978/1016). The son of Edgar, he was aged about 10 when the murder of his half-brother, Edward the Martyr, placed him on the throne. In 1002 he confirmed an alliance with Normandy by marrying, as his second wife, Duke Richard's daughter Emma – the first dynastic link between the two countries. ‘Unready’ is a mistranslation of Unraed, not recorded as his nickname until after the Norman Conquest, which means ‘ill-advised’ and is a pun on his given name, Ethelred (literally, ‘good counsel’).
