Born in around AD 870, Æthelflæd was the daughter of Alfred the Great, king of the West Saxons, and Ealhswith, a Mercian noblewoman. While not much is known about her early life, in AD 886 she went on to marry Æthelred of Mercia, marking the point she became joint ruler of the Mercian people.


After her husband’s death in AD 911, she continued to rule as sole leader another seven years and enjoyed a period of great political prosperity. Throughout her short reign and beyond, she was celebrated as a keen military strategist, diplomatic negotiator and a key player in pushing back Viking advances in the Midlands territories, paving a way for the unification of early medieval English kingdoms under subsequent rule.
