Oops, I meant Alfred The Great, not Aethelstan. The Lotus Eaters did a great documentary on him.

Alfred was an incredible King, seems (honestly) like one of the best Kings ever. I meant to basically say that as king of all the Anglos (and technically the Anglo-Saxons), that one of his biggest problems was the fact that the other Anglo kings would still try to wage war with him, while he was trying to fight off the damned Danes. Even though literal Dane Law rules a huge swathe of your country and people, and you have regular raids against your home by these foreign invaders, the Anglo-Saxons found plenty of time to fight each other, rather than the Danes.
