A new teaser trailer for Vikings: Valhalla has been released, giving viewers a hint at the action featured in this new TV show, but it focuses mostly on the London Bridge attack – and here’s the true story behind this event. One of the most popular historical dramas in recent years is Vikings, created by Michael Hirst, which premiered in 2013 and came to an end in 2020 after six seasons. However, that isn’t the end for the universe of Vikings, as it’s getting a sequel series, titled Vikings: Valhalla, set to premiere on Netflix on February 25, 2022.

Vikings covered the beginnings of the Viking Age, from the Lindisfarne raid (as seen in season 1), onward, with legendary Norse figure Ragnar Lothbrok (Travis Fimmel) as the lead. Vikings later changed its focus to Ragnar’s sons – Björn, Ubbe, Hvitserk, Sigurd, and Ivar – and their own journeys, who carried the story until the end of the series. Now, Vikings: Valhalla is a sequel series but set many, many years after the events of Vikings, covering the final years of the Viking Age, and thus following new characters (of which some have connections to those in Vikings), as are Leif Eriksson (Sam Corlett), Freydís Eiríksdóttir (Frida Gustavsson), Olaf "the Holy" Haraldsson (Jóhannes Haukur Jóhannesson), Harald Sigurdsson (Leo Suter), and more.

Set a century after Vikings, Vikings: Valhalla reportedly begins after the death of King Edward the Confessor, when three lords make claim to the English throne. Meanwhile, Leif Erikson leads Greenlanders across the North Atlantic, and his half-sister, Freydís Eiríksdóttir, has become an anti-Christian following a traumatic event involving Christian Vikings and becomes the leader of the Old Norse religion against rising Christianity in Scandinavia, and starts looking for a new home for her people. However, she’s drawn into a relationship with Torsen, a Christian Viking from a royal family who is part of a battalion assembled by King Harald Hardrada to avenge the massacre. Of course, being an extension of Vikings, viewers can expect exciting but brutal battles, and the latest teaser for Vikings: Valhalla focuses on that, showing the battle at London Bridge, which isn’t exactly historically inaccurate.

A chapter in the history of the London Bridge says it was rebuilt either by Alfred the Great (who appeared in Vikings as the illegitimate son of Judith and Athelstan, and thus was the stepson of King Aethelwulf) or under the Saxon king Æthelred the Unready around 990. Now, a skaldic tradition tells the bridge was destroyed in 1014 by Olaf II Haraldsson (later known as “Saint Olaf” or “the Holy”), an ally of Æthelred, to divide the Danish forces who held both the walled City of London and Southwark. However, the accuracy of this is still debated by historians, with some explaining that, as the Viking attack on the London Bridge isn’t mentioned in the Anglo-Saxon Chronicle, some doubt it took place. Still, the attack seems to be used in Vikings: Valhalla as the tagline in the new trailer is “London Bridge is falling down”, though with some changes to fit the story of this new generation of Vikings – after all, Hirst and company have become known for taking various creative liberties when it comes to telling the history of Vikings.

Of course, it’s possible that the battle shown in the Vikings: Valhalla teaser isn’t the London Bridge one or it’s a combination of scenes from different battles, as the series is also speculated to cover the battle that put an end to the Viking Age. Luckily, Vikings: Valhalla already has a release date, and it won’t be long until this and many other questions around the plot, its events, and characters are finally answered.
