Which Macbeth character is based on a son from The Danish House of Knytlinga?
Svein Knutsson Svein Knutsson (Old Norse: "Sveinn Knútsson") c. 1016–1035, was the son of Cnut the Great, king of Denmark, Norway, and England, and his first wife Ælfgifu of Northampton, a Mercian noblewoman. In 1017 Cnut married Emma of Normandy, but there is no evidence that Ælfgifu was repudiated, and in 1030 Cnut sent her and Svein as regents to rule Norway. However, their rule was considered oppressive by the Norwegians, and they were expelled in 1034. They imposed new taxes and harsh laws that made them unpopular. In William Shakespeare's "Macbeth", there is a character called "Sweno, the Norways' king" based on Svein.
Kenneth MacAlpin Cináed mac Ailpin (Modern Gaelic: "Coinneach mac Ailpein "), commonly anglicised as Kenneth MacAlpin and known in most modern regnal lists as Kenneth I (810 – 13 February 858), was a king of the Picts who, according to national myth, was the first king of Scots. He was thus later known by the posthumous nickname of An Ferbasach , "The Conqueror". The dynasty that ruled Scotland for much of the medieval period claimed descent from him, and the current British monarch, Queen Elizabeth II is descended from him through Malcolm III, Robert the Bruce and James VI and I.
