Is something of a mystery. There is no reference to his reign in literary sources, yet in 1840 a very large horde of coins was found at Cuerdale in the Ribble valley bearing his name, some combining the names of Cnut and Sigfrid. They were struck at York and could not have been buried later than 905–10. Since no coins of Guthrith I, who ruled at York 883–95, have been found, it has been assumed that the ‘Cnut’ coins must be his, and it is pointed out that his father's name was Harthacnut. Another suggestion is that Cnut was another name for king Sigfrid. A third identification is with a Danish noble, mentioned in Norse sources, who invaded Northumbria c.900 and established a brief rule—too brief, perhaps, for the quantity of coins produced, since he was assassinated in 902. What is clear is the comparative isolation of Northumbria at this time and the volatility of its kingship.
