STRATHCLYDE, the name given in the 9th and 10th centuries to the British (Welsh) kingdom, which from the 7th century onwards was probably confined to the basin of the Clyde, together with the adjacent coast districts, Ayrshire, &c., on the west of Scotland.
Such notices as we have of the history of Strathclyde in the 7th and 8th centuries are preserved only in the chronicles of the surrounding nations and even these supply us with little more than an incomplete record of wars with the neighbouring Scots, Picts and Northumbrians.
