Æthelflæd, The Medieval Queen Who Took on the Vikings to Save Her Kingdom


While her name is a mouthful, and quite a convoluted one at that, Æthelflæd of Mercia's role in early medieval England is rather straightforward. More importantly, the part she played in the conquest of the Danelaw (the Viking dominated region of England) is imperative to the historical tale of Britain. The eldest daughter of Alfred the Great—one of only three British rulers given such a profound epithet—Æthelflæd was not merely the daughter and wife of two astoundingly capable kings; she was as valued and looked upon as the legitimate queen following the death of her father and husband. This is the only instance of female ascension in the history of royals in Anglo-Saxon England.

A Key Political Role Amongst English Rulers

Æthelflæd grew up in a world divided. Born to an Anglo-Saxon king, the Vikings were at the height of their conquering spree in England and she married into a family constantly battling the Vikings who wanted their territory. By the time of her birth, the Great Heathen Army had already come to East Anglia and conquered them, as well as Northumbria. Her father fought against the Vikings when Ivar the Boneless led the northerners into Mercia, aiding Æthelflæd's future husband Æthelred. During these numerous skirmishes, her father—Alfred the Great—rose to become king of Wessex. By 883, Æthelred ruled Mercia under Alfred the Great's command.

Her marriage was in fact a strategic political move by her father to ensure the English kingdoms who survived the Viking invasions remained loyal to one another, in the hopes of eventually ridding their lands of the northern presence.

Though a woman, Æthelflæd had a significant role in the protection of the English from the Vikings. In the 9 th and 10 th centuries, when Æthelflæd lived and ruled, modern day England was broken down into various smaller, independent kingdoms which, themselves, were divided into tribes. Among the most prominently valued by historians are East Anglia, Mercia, Northumbria, Wessex and Gwynedd, among others. This period was also a time of furious Viking invasions, the Viking period having begun with the pillaging of Lindisfarne in 793 and continuing throughout the 11th century. Thus, Æthelflæd lived around the mid-point of these Viking invasions.

Lady of the Mercians

She and her brother were tasked by Alfred the Great with ensuring the continuous building of fortified structures called ‘burhs’. The idea behind these burhs was to create a strategic network of defenses against the Vikings that the English could easily reach and move between. These burhs were both reused Iron Age or Roman fortifications and brand new structures commissioned by either Alfred or his children. Æthelflæd herself is attributed with directly instigating the burhs at such locations as Tamworth and Stafford, the former significant from Roman times onward, while the latter was founded by a Mercian prince in the 8 th century. Stafford in particular holds interest to scholars of Æthelflæd, "Lady of the Mercians", as she commandeered it after both her father and husband died, securing the city as a prime military base.

This new role as "Lady of the Mercians" was in essence an acknowledgement of her queenship following the death of her husband, allowed due to Mercian traditions, not her native Wessex ones. Not only was the Lady gaining territory in her own name rather than her and her husband's, Æthelflæd also led many of her Mercian armies into battle, aiding her brother's attempts to displace the southern Danes by splitting the focus of the Vikings armies.

The Strengths of a Saxon Queen

That Æthelflæd succeeded in defeating various Viking armies is a feat in and of itself for a medieval woman. That she did so without a husband, without her father or brother's aid, and with the full support of her Mercian people speaks volumes of the impact Æthelflæd had on the lives and events of 10th century Mercia and Wessex. It is a testament both to her upbringing and her individual intellect and pride. Tamworth and Stafford remain two valued locations in modern day England, and thus stand as monuments to the woman who procured them as powerful military command centers against the Viking invaders. Though Æthelflæd graced no coinage in her time, her actions graced her native and wedded kingdoms in aiding in the safety of her people.

Have you thought about writing an article for "Ancient Origins" making the distinctions between the peoples of the British Isles so that readers and hopefully future writers will be more correct in their articles?

We have the same problem over here, for the most part, the teaching of English history is lacking, in fact, the period between the fall of the Roman Province and 1066 is hardly touched upon, therefore such historical figures as Athelfead or Alfred her Father are for the most part forgotten.

In point of fact the Education system over here is laughably Politically Correct, perhaps laughably is the wrong word, perhaps dangerous is more apt? For the most part, revisionism to suit a political agenda?

a people who have no knowledge of their heritage, origins and past, have no future!!

Believe it or not, the whole of the UK is often lumped as simply England here in the USA. Our public education system is somewhat lacking.

Yes, each state has its own flag. But that was not true in the USA until the War Between the States. The US flag served all the states until then.

Yes, that does explain much, the on going mix of England/Britain and visa-versa, and English/British while the Scots are Scots, Welsh are Welsh and the Irish are Irish, yet while we English and our Country are simply lumped as British and the Flag of the Political Union of Great Britain is marked as England's flag when it is obviously not, but the flag of the whole of the British Union. It would be construed as an insult to any State of the US, if the Stars and Stripes were put down over here in England as the flag of one particular State in the US, when it is not, I believe State has its own State flag?

My problem with the simplifying of things in Britain by historians and none historians in the US, is that with the crumbling state of the Union in Britain since the introduction of the rather unequal and lob-sided Devolution, where England is missed out altogether, E.G. without its own Parliament, the lumping of the English with the term British/English and England/Britain is becoming offensive, as it would in Scotland or Wales or Northern Ireland if they were lumped in as English and therefore England!

One major problem with "historians" is that they often conflate history. One example is to read the history of England in the united States. It usually begins with the Beaker peoples, the goes on to the Celts, and the Roman invasion, etc. The only problem is that none of these peoples were English. The English had not yet arrived on the Island of Britannia. It gets worse when the history of Ireland it studied here. There is no distinction between the English and the Normans. Now we get to America, though the different peoples from the various "nations" of England and the British Islands are distinct, each with their own customs and views of life, most Americans are taught that they were all English as if there is some sort of homogenization of the peoples. That is not how America was settled and hence though most of America's culture is from the British Isles, nevertheless, the different regions reflect those cultural and value differences that were inherited from the British Isles. In other words, the peoples of America are different according to their British origins and continued history. In many ways they are growing apart and not together.
