Стратклайд
At some point after the loss of Al Clud, the Kingdom of Strathclyde appears to have undergone a period of expansion. Although the precise chronology is uncertain, by 927 the southern frontier appears to have reached the River Eamont, close to Penrith. The catalyst for this southern extension may have been the dramatic decline of the Kingdom of Northumbria at the hands of conquering Scandinavians, and the expansion may have been facilitated by cooperation between the Cumbrians and insular Scandinavians in the late ninth- and early tenth century. Over time, the Kingdom of Strathclyde increasingly came to be known as the Kingdom of Cumbria reflecting its expansion far beyond the Clyde valley.
