The Old North (Welsh: Hen Ogledd, Welsh pronunciation: [ˌheːn ˈɔɡlɛð]) is the term used in modern scholarship for the historical and literary space which was inhabited by Brittonic-speaking peoples of modern Northern England and southern Scotland in the Early Middle Ages. The people of Wales and those of the Old North considered themselves to be one people, and both were referred to as Cymry ('fellow-countrymen') from the Brittonic word combrogi. The Old North was distinct from the parts of Great Britain inhabited by the Picts, Anglo-Saxons, and Scoti.
The major kingdoms of the Old North were Elmet, Gododdin, Rheged, and the Kingdom of Strathclyde (Welsh: Ystrad Clud). Smaller kingdoms included Aeron and Calchfynydd. Eidyn, Lleuddiniawn, and Manaw Gododdin were evidently parts of Gododdin. The later Anglian kingdoms of Deira and Bernicia both had Brittonic-derived names, suggesting they may have been Brittonic kingdoms originally. All the kingdoms of the Old North except Strathclyde were gradually either integrated or subsumed by the emerging Anglo-Saxon kingdoms, Gaelic Scots and fellow Brittonic Picts by about 800; Strathclyde was eventually incorporated into the rising Middle Irish-speaking Kingdom of Scotland in the 11th century.
