Guðrøðr Rǫgnvaldsson

Guðrøðr Rǫgnvaldsson, also known as Guðrøðr Dond, was a thirteenth-century ruler of the Kingdom of the Isles. He was a member of the Crovan dynasty, and a son of Rǫgnvaldr Guðrøðarson, King of the Isles, the eldest son of Guðrøðr Óláfsson, King of Dublin and the Isles. Although the latter may have intended for his younger son, Óláfr, to succeed to the kingship, the Islesmen instead settled upon Rǫgnvaldr, who went on to rule the Kingdom of the Isles for almost forty years. The bitterly disputed royal succession divided the Crovan dynasty for three generations, and played a central role in Guðrøðr's recorded life.
