King & Conqueror dropped on 24 August 2025, with all eight episodes releasing together. In episode 1, the show builds the foundation of the rivalry between Harold Godwinson, the Anglo-King, and William, the Duke of Normandy. Without directly introducing the Battle of Hastings, the show first chose to brew the drama layered with some political intrigue, personal tensions, and circumstances that led the two men into Battle.
William and Harold's first encounter in the show is ironic, as one of the men was initially saved by another, only to later go thirsty for each other's blood. When William enters England, he is ambushed by bandits alongside the English Channel, and here enters Harold, who saves him at the last moment. This establishes Harold as both capable and noble because he saved William, even when he was a foreigner.
Here is how William and Harold meet in episode 1 of King & Conqueror
As mentioned, William experienced a close call with the Bandits, and the moment he was about to be killed, Harold saved him, cutting through the enemies. Harold believes that Mercians, a rival faction in England, is behind the attack, and while looking for proof, he ends up saving William. This also tells the viewers about the political scenario in England and the instability of Wessex.
William is then welcomed into King Edward's court, who is delighted to see his cousin, while their mother Emma is emotional. But it is only later that we get to sense the politics brewing beneath the sheets. Edward and Emma wanted William's military as an ally, essentially making Normandy England's enforcer.
William realises that he's not being valued for his family ties but for his army strength. William, refusing to just be Edward's muscle, sees it as an offence. This sows the seeds of tension, though William chose to remain around for family and duty in King & Conqueror.
What does it mean for King & Conqueror?

Harold saving William sets up an ironic bond in King & Conqueror: the two men destined to be enemies once shared respect and even saved each other’s lives. It also sets up how William is always seen as a foreigner or outsider, respected for his military power but never fully embraced by the English.
Under Edward's rule, Harold is the Earl of Wessex, the most influential noble under a confessor who is now old and doesn't have any heir. One of the key moments in episode 1 showcases Harold swearing an oath to have loyalty towards William. This marks a crucial moment, as eventually Harold takes the throne, and William considers it a betrayal.
After Edward's death, Harold, being the righteous one, even though not a relative, was crowned as king. This affected William, who is a distant cousin and was promised the throne. He announces battle, and that is how the Battle of Hastings occurred, when William's powerful army killed Harold, the King, and William became the King of the English land. This is the reason they are considered as "Harold as the King and William the Conqueror."
