Shieldmaiden
A shieldmaiden (Old Norse: skjaldmær, Danish: skjoldmø, Norwegian: skjoldmøy, Swedish: sköldmö, German: Schildmaid) was a woman who had chosen to fight as a warrior in Scandinavian folklore and mythology. They are often mentioned in sagas such as Hervarar saga ok Heiðreks and in Gesta Danorum. Shieldmaidens also appear in stories of other Germanic peoples: Goths, Cimbri, and Marcomanni. The mythical Valkyries may have been based on the shieldmaidens. The historical existence of shieldmaidens is heavily debated, but scholars including Lars Magnar Enoksen,Neil Price and scholar Britt-Mari Näsström argue evidence for their existence, while scholar Judith Jesch disagrees, citing lack of hard evidence.
Historical accounts
There are few historic attestations that Viking Age women took part in warfare, but the Byzantine historian John Skylitzes records that women fought in battle when Sviatoslav I of Kiev attacked the Byzantines in Bulgaria in 971. When the Varangians (not to be confused with the Byzantine Varangian Guard) had suffered a devastating defeat in the Siege of Dorostolon, the victors were stunned at discovering armed women among the fallen warriors.
