Olaf Cuaran

Amlaíb mac Sitric, commonly called Amlaíb Cuarán, was a 10th-century Norse-Gael who was King of Northumbria and Dublin. His byname, cuarán, is usually translated as "sandal". His name appears in a variety of anglicized forms, including Olaf Cuaran, Anlaf Sihtricson and Olaf Sihtricson, particularly in relation to his short-lived rule in York. He was the last of the Uí Ímair to play a major part in the politics of the British Isles.
