Strathclyde

A British kingdom in the Lowlands of Scotland in the traditional Arthurian period. The names and dates of the kings are uncertain.

According to Sir Walter Scott’s The Bridal of Triermain, Arthur promised this western Scottish kingdom to whichever knight married Gyneth, his daughter. In this sixth century, it was ruled by Rhydderch the Generous, who is connected to Merlin in Welsh legend.
