It is also known as Alt Clut, a Brittonic term for Dumbarton Castle, the medieval capital of the region.
It may have had its origins with the Brythonic Damnonii people of Ptolemy's Geography.
Twice it was advanced to the line of the Antonine Wall, at about the time when Hadrian's Wall was built and again under Septimius Severus, and once further north, beyond the river Tay, during Agricola's campaigns, although, each time, it was soon withdrawn.
In addition, a group known as the Maeatae, probably in the area around Stirling, appear in later Roman records.
The capital of the Damnonii is believed to have been at Carman, near Dumbarton, but around five miles inland from the River Clyde.
The language of Strathclyde, and that of the Britons in surrounding areas under non-native rulership, is known as Cumbric, a dialect or language closely related to Old Welsh, and in modern terms to Welsh, Cornish and Breton.
Scottish toponymy and archaeology points to some later settlement by Vikings or Norse–Gaels (see Scandinavian Scotland), although to a lesser degree than in neighbouring Galloway.Although often referred to as the Dark Ages, the period after the end of Roman rule in southern Scotland, while poorly understood, is considerably less dark than the Roman period.Archaeologists and historians have offered varying accounts of the period over the last century and a half.or Alclud (and Strath-Clota in Anglo-Saxon), was one of the early medieval kingdoms of the Britons in Hen Ogledd ("the Old North"), the Brythonic-speaking parts of what is now southern Scotland and northern England.
