Æthelred the Unready, English son of Edgar the Peaceful (b. 968)
Æthelred II (Old English: Æþelræd, pronounced [ˈæðelræːd]; c. 966 – 23 April 1016), known as the Unready, was King of the English from 978 to 1013 and again from 1014 until his death in 1016. His epithet does not derive from the modern word "unready", but rather from the Old English unræd meaning "poorly advised"; it is a pun on his name, which means "well advised".
Æthelred was the son of King Edgar the Peaceful and Queen Ælfthryth. He came to the throne at about the age of 12, following the assassination of his older half-brother, King Edward the Martyr. Æthelred's mother may have ordered the murder of his half-brother in order to place Æthelred on the throne.The chief problem of Æthelred's reign was conflict with the Danes. After several decades of relative peace, Danish raids on English territory began again in earnest in the 980s, becoming markedly more serious in the early 990s. Following the Battle of Maldon in 991, Æthelred paid tribute, or Danegeld, to the Danish king. In 1002, Æthelred ordered what became known as the St. Brice's Day massacre of Danish settlers.
In 1013, King Sweyn Forkbeard of Denmark invaded England, as a result of which Æthelred fled to Normandy in 1013 and was replaced by Sweyn. After Sweyn died in 1014, Æthelred returned to the throne, but he died just two years later. Æthelred's 37-year combined reign was the longest of any Anglo-Saxon English king, and was only surpassed in the 13th century, by Henry III. Æthelred was briefly succeeded by his son, Edmund Ironside, but he died after a few months and was replaced by Sweyn's son Cnut. Another of Æthelred's sons, Edward the Confessor, became king in 1042.
