Ælfthryth (wife of Edgar) in the context of "Queen of the English"

Æthelred II c.968 – 23 April 1016), known as Æthelred the Unready, was King of the English from March 978 to December 1013 and again from February 1014 until his death in April 1016. He was the son of King Edgar (reigned 959–975) and Queen Ælfthryth. Æthelred came to the throne after the assassination of his older half-brother, King Edward the Martyr, a crime which deeply shocked people. The epithet "Unready" is a pun on his name in Old English, Æthel (noble) and ræd (counsel).

Shortly after Æthelred's accession Viking attacks resumed after a generation of peace. Minor raids in the 980s escalated to large scale attacks from the 990s, and as the English were rarely victorious in battle the king and his advisers resorted to giving the Vikings tribute to leave England, payments which are often (incorrectly) called Danegeld. In the 1000s increasingly destructive raids by Viking armies wore down English resistance, and in December 1013 King Swein Forkbeard of Denmark conquered England. Æthelred fled to Normandy, but when Swein died in February 1014 he was able to return to the throne and drive out Swein's son Cnut. In early 1015 civil war broke out when Æthelred's favourite Eadric Streona murdered close allies of Æthelred's oldest surviving son, Edmund Ironside. Cnut returned soon afterwards and Edmund and Æthelred tried to unite against him, but they were hampered by suspicion between them, Eadric's treachery and Æthelred's poor health. He died in April 1016 and Edmund carried on the war until he died in December 1016 and Cnut became king of all England.

Edward the Martyr (c. 962 – 18 March 978) was King of the English from 8 July 975 until he was killed in 978. He was the eldest son of King Edgar (r. 959–975). On Edgar's death, the succession to the throne was contested between Edward's supporters and those of his younger half-brother, the future King Æthelred the Unready. As they were both children, it is unlikely that they played an active role in the dispute, which was probably between rival family alliances. Edward's principal supporters were Dunstan, Archbishop of Canterbury, and Æthelwine, Ealdorman of East Anglia, while Æthelred was backed by his mother, Queen Ælfthryth and her friend Æthelwold, Bishop of Winchester. The dispute was quickly settled. Edward was chosen as king and Æthelred received the lands traditionally allocated to the king's eldest son in compensation.

Edgar had been a strong and overbearing king and a supporter of the monastic reform movement. He had forced the lay nobility and secular clergy to surrender land and sell it at low prices to the monasteries. Æthelwold had been the most active and ruthless in seizing land for his monasteries with Edgar's assistance. The nobles took advantage of Edgar's death to get their lands back, mainly by legal actions but sometimes by force. The leading magnates were split into two factions, the supporters of Ælfhere, Ealdorman of Mercia, and Æthelwine, who both seized some monastic lands which they believed belonged to them, but also estates claimed by their rivals. The disputes never led to warfare.

Shortly after Æthelred's accession, Viking attacks resumed after a generation of peace. Minor raids in the 980s escalated to large attacks from the 990s. As the English were rarely victorious in battle, the king and his advisers resorted to giving the Vikings tribute to leave England. In 1002 Æthelred ordered the St Brice's Day massacre of Danes, which is seen by historians as a sign of his increasing paranoia, and this culminated by 1009 in the rise of Eadric Streona to become the most powerful of Æthelred's advisers. Increasingly destructive raids by Viking armies wore down English resistance, and in December 1013 King Swein Forkbeard of Denmark conquered England. Æthelred fled to Normandy, but when Swein died in February 1014 he returned to the throne and drove out Swein's son Cnut.
