The Norman's conquest of England would certainly be a soap opera, and an occasionally humorous one at that. The political situation in 11th century England was rife with conflict between Englishmen, Normans, and Vikings.
King Edward, who ruled England, failed to produce an heir. He purportedly offered the throne to Duke William of Normandy upon his death. In the famous scene from the Bayeux Tapestry, Harold Godwinson, King Edward's advisor and the second wealthiest man in England, swore on holy relics that William would be the next king. Harold had supposedly been sent to Normandy to tell William, although by other accounts, he was coerced into making this promise. Either way, when King Edward died in January 1066, the English council, called the witan, didn't choose William to be king but rather chose Harold Godwinson for the throne. King Harold I ruled until his death at the Battle of Hastings on October 14, 1066.
A few days before the Battle of Hastings, King Harold was in the north of England fighting his own brother, Tostig, and Harald Hardrada, the king of Norway. Both men died in their battle with Harold. Shortly after, William of Normandy arrived on the southern coast of England.
When William of Normandy arrived in England, he was looking for a fight. He marched through the south and finally met Harold's forces—which he had hastily gathered together as he rushed back from the north—at Hastings. William and his Norman forces were victorious at Hastings; King Harold I died at the battle, and England found itself under the authority of a new,Norman king.
You can't make this stuff up and it's rife with song material. "Emma, wife and mother of Kings" and "Harold, not Harald" help explain the genealogy. "That Liar!" could cover William's indignation.
