I don't remember learning anything about him other than his name and that he was the first King of the Anglo-Saxons. You'd really think they'd tell us more about him, he seemed pretty cool and very relevant to English history.
I grew up in Somerset, and didn't even know that he hid from Danish invaders in the Somerset levels until I watched The Last Kingdom. That could have been a dope school trip.
I learned very briefly in Australia, but it was like a paragraph. Then I learned the opera by Arne, which is pretty dope (it's where Rule Britannia comes from, sung at the end after Alfred commands the construction of the British navy)
