Origins of the Kingdom of Alba
I feel that this section gives unnecessary complex detail already in the linked article of the same name, and emphasises the idea that this is a history of Alba rather than the whole of what became Scotland. It would be better to have a brief outline of how immediately post-Roman the Caledonii? to the north of the Antonine wall became Alba -  brief summary of Picts / Gaelic Scots as here and mention of Viking incursions, while the friendly buffer tribal areas became the Kingdom of the North, thence Kingdom of Strathclyde, Galloway and Northumbria. This should be much shorter than the current section, and main articles linked would be Scotland in the Early Middle Ages and Origins of the Kingdom of Alba. I'll try to draft this soon. ...: talk
