During the period 1146-1157 the Danish kingdom was split between two rival kings, Canute V and
Sweyn III. In 1154, Canute allied with his kinsman
Valdemar, the future King Valdemar the Great, and sought support from his stepfather
Sverker I of Sweden. During his stay he was engaged to a daughter of Sverker, while Valdemar betrothed Sverker's stepdaughter
Sophia of Minsk. The name of Canute's fiancée is not mentioned in the chronicles. However, it has been assumed by modern research that her name was Helen, also called Elin. The basis for this conclusion is the
Necrologium Lundense which mentions an
Elena Regina with the death date 31 December. Since no other Danish queen of that name is known, it is likely that Sverker's daughter is meant. According to a hypothesis she may be identified with a non-official semi-legendary saint called Helen who was venerated in Sweden and, apparently, Denmark. ==Queen of Denmark==
