Stafford sees her as a "warrior queen", "Like ... ElizabethI she became a wonder to later ages." According to Charles Insley,  Wainwright sees Æthelflæd as willingly accepting a subordinate role in a partnership with her brother and agreeing to his plan of unification of Wessex and Mercia under his rule. Wainwright argues that he probably sent his oldest son Æthelstan to be brought up in Mercia, to make him more acceptable to the Mercians as king; Æthelflæd does not appear to have tried to find a husband for her daughter, who must have been nearly thirty by 918. In Wainwright's view, she was ignored in West Saxon sources for fear that recognition of her achievements would encourage Mercian separatism:  Simon Keynes points out that all coins were issued in Edward's name, and while the Mercian rulers were able to issue some charters on their own authority, others acknowledged Edward's lordship. In 903 a Mercian ealdorman "petitioned King Edward, and also Æthelred and Æthelflæd, who then held rulership and power over the race of the Mercians under the aforesaid king". Keynes argues that a new polity was created when Æthelred submitted to Alfred in the 880s, covering Wessex and English (western) Mercia. In Keynes's view, "the conclusion seems inescapable that the Alfredian polity of the kingship 'of the Anglo-Saxons' persisted in the first quarter of the tenth century, and that the Mercians were thus under Edward's rule from the beginning of his reign". Ryan believes that the Mercian rulers "had a considerable but ultimately subordinate share of royal authority". In Higham's view, Keynes makes a strong case that Edward ruled over an Anglo-Saxon state with a developing administrative and ideological unity but that Æthelflæd and Æthelred did much to encourage a separate Mercian identity, such as establishing cults of Mercian saints at their new burhs, as well as reverence for their great Northumbrian royal saint at Gloucester:  In June 2018, Æthelflæd's funeral was re-enacted in front of a crowd of 10,000 people in Gloucester, as part of a series of living history events marking the 1,100th anniversary of her death. The 1,100th anniversary of the death of Aethelflaed was marked throughout 2018 in Tamworth with a number of major events, including the unveiling of a new six-metre statue, the creation of the town's biggest ever piece of community art, a major commemorative church service, talks, a special guided walk, commemorative ale and an academic conference weekend drawing academics and delegates from all over the world.
