'Vikings': Lagertha, the 8th-century shieldmaiden is the feminist icon of today
Lagertha is the only woman on the show with a major role to play and her fandom expands beyond Ragnar's simply because she is the sassiest bada** on television today
Ragnar Lothbrok, the protagonist of 'Vikings,' is long dead (season 4), and fans are currently invested in exploring the heroic complexities of his sons, but what is actually holding the storyline together even after the protagonist's death is the heroic hold of Lagertha, Ragnar's first wife, who has not only grown to be the most loved character among fans, but also established herself to be a feminist icon of today.
The 8th-century woman, according to history, was the key to Ragnar's victory against the king of Sweden, Frø, and has been portrayed in the television series as an iron shieldmaiden ruling Kattegat in season 5.
