Historian seeks recognition for first English king
https://www.bbc.com/news/articles/c9d07w50e15o
Somewhere I have a list of Anglo-Saxon, Wessex and English kings.
Well there is nothing new there. Parts of Britain experienced tribal rivalries/conflicts as well as invasions by the Romans, Vikings/Norsemen, Angles, Saxons and Jutes, then Normans, and various monarchs/emperors declared war on other monarchs/emperors. Seems that behavior has not ceased.
