Kingdom of Strathclyde

Brittonic kingdom in early medieval Britain

Strathclyde (Welsh: Ystrad Clud, 'Valley of the Clyde'), also known as Cumbria, was a Brittonic kingdom in northern Britain during the Middle Ages. It comprised parts of what is now southern Scotland and North West England, a region the Welsh tribes referred to as Yr Hen Ogledd ('the Old North'). At its greatest extent in the 10th century, it stretched from Loch Lomond in the north to the River Eamont at Penrith in the south.
