The Last Kingdom season four was released on Netflix earlier in 2020 and fans saw the death of antagonist Aethelred (played by Toby Regbo). The Mercian ruler had been severely injured during the Battle of Tettenhall and his life was eventually ended by his commander Eardwulf (Jamie Blackley). Express.co.uk has explained why Regbo left the series.
Aethelred was introduced to the series in season two, and he was partnered with King Alfred's (David Dawson) daughter Aethelflaed (Millie Brady).
He quickly became one of the most hated characters in the series as he had a selfish nature and treated his young wife particularly badly.
Season four introduced two new characters - Eardwulf and his sister Eadith (Stefanie Martini) who had set out to overthrow Aethelred and claim back their family's reputation.
Eadith acted as Aethelred's mistress, against her will, while Eardwulf attempted to win over his trust as his commander during battles.
However, when Eardwulf realised the only way to win power was to kill Aethelred, he decided to murder the dying ruler.

Aethelred had been left severely injured following the Battle of Tettenhall, when he fell backward and hit his head.
He was saved and brought back to the kingdom but realised he was dying and in his last moments, fans saw him in a completely different light.
They started to feel sorry for him as he apologised to his wife for the way he had treated her and gave her permission to choose a suitable husband for their own daughter.
For a moment, fans believed the years of abuse and conflict had finally come to an end. But Eardwulf saw this as the perfect opportunity to kill Aethelred.
He believed no-one was watching when he broke Athelred's neck, but his sister Eadith saw the whole thing.
