Thyra or Thyri (Old Norse: Þyri or Þyre) was the wife of King Gorm the Old of Denmark, and one of the first queens of Denmark believed by scholars to be historical rather than legendary. She is presented in medieval sources as a wise and powerful woman who ordered the building or fortification of the Danevirke, consistent with her commemoration on multiple Viking Age runestones. These include those at Jelling which was the seat of power for her dynasty.

Although her existence is documented in Viking Age runic inscriptions, very little is known about Thyra with certainty as no other contemporary sources about her survive.^[1] Much of her story is pieced together through 12th and 13th century sources that broadly disagree with one another, such as Icelandic sagas and writings of the medieval historians Saxo Grammaticus and Sven Aggesen. When she was born and became queen is unclear, however, she likely ruled until her death in the middle of the 10th century. Historians widely agree that she and Gorm were the parents of Harald Bluetooth and likely also Canute. The Historia Norwegiæ additionally claims that they had a daughter, Gunnhild, Mother of Kings, though this is less certain.

Thyra's name is attested in Old Norse as Þyri and Þyre and has been alternatively anglicised as Thorvi and Thyre.^[2][3][4]

The Jelling 1 stone, commissioned in honour of Thyra by her husband after her death refers to her as Danmarkar bót, translating as "Denmark's adornment", "strength", "salvation" or "remedy".^[5][6] It has been further argued that the words Danmarkar bót instead refer to Gorm, with Thyra's importance being a later innovation by medieval writers, though this is not the scholarly consensus.^[5][7] This term is also used to describe her in Saga Hálfdanar svarta as Danmarkar bótar (sometimes anglicised as "Dannebod").^[2]

Thyra's parentage is unclear, with accounts produced by medieval historians and in Icelandic sagas during the 12th and 13th centuries being dubious and contradictory. They variously describe her as the daughter of an English king and a king in Jutland.^[8][9]

In the twelfth-century Gesta Danorum, Saxo Grammaticus describes her as the daughter of King Æthelred the Unready. His grandson Harold Bluetooth plundered England, and Æthelred so admired Harold's manliness that he disinherited his own son in Harold's favour. Æthelred's son and grandson made Harold's descendants their heirs. A consequence of this stressed by Saxo is that Cnut's claim to the English king was both by a claim repeatedly recognised and by battle. Saxo implies that Danish kings in his own time had a valid claim to the English throne.^[10][11]

According to Sven Aggesen, Thyra was of German origin and her marriage to Gorm had been arranged by the German emperor to whom Gorm owed a large tribute. Having installed Thyra as Gorm's wife, she was to collect the tribute for the emperor. Aggesen claims that Thyra refused to pay the emperor, heroically declaring that the Danes were no longer a tributary to the Kingdom of Germany.^[1]

Little is known concretely about Thyra's role as queen consort of Denmark, nor the circumstances of her marriage to Gorm and their children. Gorm became king around 936 CE, however it is unknown if he was already married to Thyra, and it is not known when she became queen.^[5] Based on the prominence of Thyra seen in the runestone record, it has been proposed that Thyra may have been of the pre-existing royal line and that Gorm became king through marriage with her.^[6]

Historians widely agree that she and Gorm were the parents of Harald Bluetooth, who commissioned the Jelling 2 runestone in their honour, and to a lesser extent it is agreed that they also had a son called Canute.^[5][12] The Historia Norwegiæ additionally claims that they had a daughter, Gunnhild, Mother of Kings, though this is not corroborated by any other evidence.^[13] Further details of her marriage and children are provided in the Gesta Danorum and the Jómsvíkinga saga, among other medieval sources. However, these sources are subject to great scrutiny and do not provide a consensus on her life.

The Gesta Danorum claims that Thyra stood out as a serious and cunning woman and said that she would not marry Gorm until she had all of Denmark as her dowry. When this was agreed, she was betrothed to him but asked him not to have sex with her when they shared a bed for the first three nights until she had had a vision that their marriage would go well. Gorm agreed and laid a drawn sword between them in the bed, and at night he dreamed that a large bird and a smaller one flew out of his wife's womb and flew up into the sky and sat on each of his hands. Again they flew off and came back but the third time when they flew away, only the smaller bird came back and its wings were covered in blood. At this, Gorm woke and cried out, telling his vision to his servants and Thyra took it to mean that they would have children together. She later gave birth to Canute and Harald.^[14][1]

Aggesen and Saxo Grammaticus record that Thyra was a wise and steadfast queen who ordered the building of the Danevirke, a system of fortifications built to protect Denmark from invaders from the south.^[5] According to Aggesen, Thyra ordered the construction of the Danevirke as part of her plan to end Denmark's role as a tributary to the Kingdom of Germany. She is reported to have deceived the German emperor into believing that the fortifications she was constructing on the border were to protect Germany from a invasion from her husband Gorm.^[1] The Historia Norwegiæ further attests to Thyra's wisdom, contrasting her astuteness with the foolishness of Gorm.^[13]

The first phase of construction has been shown to predate Thyra's reign, with some trees in the fortification having been felled in 737 CE, however the defences were extended significantly several times until the 12th-century CE.^{[12][15][16][17]}

The northern howe at Jelling, the seat of power for Gorm's dynasty, is traditionally known as Thyras Høj ("Thyra's mound"), with the southern as Gorm's, although when excavated, no evidence of a body was found in it. Wooden artefacts from the howe have however been dated by tree-ring analysis to 959-960 CE which would put this as the latest date for Thyra's death if it is indeed her grave.^[5][18][19]

It has been proposed that her burial in the larger, northern barrow is consistent with the idea of her as a prominent woman who may have been even more powerful than her husband Gorm.^[5]

Gorm died around 963 CE and while Saxo records in Gesta Danorum that Thyra died after her husband, it is typically believed that Thyra died before Gorm due to the Jelling 1 stone which he raised to commemorate her.^[20][21]

Along with two runestones at the royal site of Jelling dating to the mid 10th century CE, the name Thyra is recorded on five more from Viking Age Denmark - Laeborg (DR 26), Bække 1 and 2 (DR 29 and 30), Horne (DR 34) and Randbøl (DR 40). Although all seven stones reference a woman called Thyra, it has been debated whether they refer to the same person.^[5]

It has been proposed however, based on analysis of factors such as groove depth, rune shape and spelling, that a single runecarver named Ravnunge-Tue (who is one of the earliest known Western European artisans to have carved his name on his work as the maker) wrote the inscriptions both on the Læborg and Jelling 2 stones, while another individual carved the Horne, Bække and possibly the Randbøl stones. From this, it has been argued that the Jelling stones, the Læborg stone and Bække 1 commemorate the same woman named Thyra. If correct, she would be recorded on at least four runestones - the most for anyone in Viking Age Denmark, exceeding both Gorm the Old and Harald Bluetooth. Following this, it has been suggested that she was either one of the individuals or even the leading figure who drove the assembly of the Danish kingdom.^[5]
