Who is Aethelflaed in The Last Kingdom?

The Lady of Mercia, twice underestimated · Wessex & the Church

Aethelflaed (The Lady of Mercia, twice underestimated) is a character in The Last Kingdom, part of Wessex & the Church. Aethelflaed grows up as Alfred's clever daughter and is spent as Alfred's treaty — married into Mercia's contempt, hostaged in Dane camps, underestimated by every man at every table. The series' best long arc is hers: from political token to the Lady of Mercia, fortress-builder and battle commander, holding her father's dream with steadier hands than her brother. Her bond with Uhtred — protector, lover, impossible match — is the show's most adult romance: two people who choose duty, repeatedly, on purpose.
