Æthelflæd, Lady of the Mercians (died 12 June 918), ruled Mercia in the English Midlands from 911 until her death. She was the eldest daughter of Alfred the Great, king of the Anglo-Saxon kingdom of Wessex, and his wife Ealhswith. Æthelflæd was born around 870 at the height of the Viking invasions of England. By 878 most of England was under Danish Viking rule, East Anglia and Northumbria having been conquered and Mercia partitioned between the English and the Vikings, but in that year Alfred won a crucial victory at the Battle of Edington. Soon afterwards the English-controlled western half of Mercia came under the rule of Æthelred, Lord of the Mercians, who accepted Alfred's overlordship. Alfred adopted the title King of the Anglo-Saxons, claiming to rule all English people not living in areas under Viking control. In the mid-880s, Alfred sealed the strategic alliance between the surviving English kingdoms by marrying Æthelflæd to Æthelred.

Æthelred played a major role in fighting off renewed Viking attacks in the 890s, together with Æthelflæd's brother, the future King Edward the Elder. Æthelred and Æthelflæd fortified Worcester, gave generous donations to Mercian churches and built a new minster in Gloucester. Æthelred's health probably declined early in the next decade, after which it is likely that Æthelflæd was mainly responsible for the government of Mercia. Edward had succeeded as King of the Anglo-Saxons in 899, and in 909 he sent a West Saxon and Mercian force to raid the northern Danelaw. They returned with the remains of the royal Northumbrian saint, Oswald, which were translated to the new Gloucester minster. Æthelred died in 911 and Æthelflæd then ruled Mercia as Lady of the Mercians. The accession of a female ruler in Mercia is described by the historian Ian Walker as "one of the most unique events in early medieval history".
