Cadwaladr

Cadwaladr

Cadwaladr ap Cadwallon (also spelled Cadwalader or Cadwallader in English) was king of Gwynedd in Wales from around 655 to 664 or 682. He died in one of two devastating plagues that happened in 664 and in 682. Little else is known of his reign. The red dragon (Welsh: y Ddraig Goch), long known as a Welsh symbol, appearing in the Mabinogion, the Historia Brittonum, and the stories of Geoffrey of Monmouth, has, since the accession of Henry VII to the English throne, often been referred to as "The Red Dragon of Cadwaladr".
