According to historian Anders Winroth, Christianity was not forced upon Scandinavians by foreign states or foreign missionaries, but instead willfully adopted by Scandinavian kings who saw the religion as politically advantageous.

The spread of Christianity in Denmark occurred intermittently. Danes encountered Christians when they participated in

were also the location of Denmark's great assembly places (Danish: ''landsting''). Religious sites in Denmark were often located at sacred springs, magnificent beech groves, or isolated hilltops. Missionaries simply asked to build chapels in those places. Over time the religious significance of the place transferred itself to the chapel. Even after becoming Christian, Danes blended the two belief systems together. Families who lived close to the earth did not want to offend the local spirits (Danish: ''landvætter''), so offerings were left just as they had been in pre-Christian times. Sacred springs (Danish: ''kilder'') were simply consecrated to one of the local saints associated with the spring and life went on much as it had before. Christian missionaries were able to help the process along by locating churches on or near sacred places, in some cases actually using wood from the sacred groves for church construction.

on the island of Zealand. Sweyn rebelled against his father, who spent an inordinate amount of time and money raising a great stone at Jelling to commemorate his accomplishments. One day King Harald asked a traveller if he had ever seen human beings move such a heavy load. "I have seen Sweyn drag all of Denmark away from you, sir. Judge for yourself which of you bears the heavier weight." Harald left the stone lying in the path, realizing at last that Sweyn had nearly succeeded in stealing the whole kingdom. Several battles brought the rebellion to stalemate, but in 985 Harald was wounded by an arrow and later died in Jomsborg. Sweyn Forkbeard tried to wrest control of the church in Denmark away from the

and as a result was slandered by German historians of his day. He has been accused of relapsing from his Christian beliefs and persecuting Christians in England. In fact Sweyn gave land to the large cathedral at Lund to pay for the maintenance of the chapter. His army destroyed Christian churches in England as part of his invasion following the St. Brice's Day massacre of Danes organized by Aethelred. But when Sweyn became King of England and of Denmark, politics required that he show a kinder face toward the church which had opposed him. Another Christianizing influence was the mass emigration of Danes to England and Normandy in the Viking years. Thousands of Danes settled in east central England and in northern France displacing or intermarrying with the locals who were Christian. Once part of a Danish clan became Christian, it often meant that the rest of the family's view toward Christianity softened. By the early 11th century, certainly during the reign of Canute IV, Denmark can be said to be a Christian country. Later known as St. Canute, Canute IV was murdered inside St. Albans Church in 1086 after nobles and peasants alike rebelled at his enforcing the tithe to pay for the new monasteries and other ecclesiastical foundations which were introduced into Denmark for the first time during his reign. Both the institutions and the tax were considered foreign influences, and Canute's refusal to use the regional assemblies as was customary to establish new laws, resulted in his death and that of his brother, Prince Benedict, and seventeen other housecarls. In many ways the

Haakon the Good Haakon Haraldsson (c. 920–961), also Haakon the Good (Old Norse: ''Hákon góði'', Norwegian: ''Håkon den gode'') and Haakon Adalsteinfostre (Old Norse: ''Hákon Aðalsteinsfóstri'', Norwegian: ''Håkon Adalsteinsfostre''), was the king o ...
in the tenth century, who was raised in England. His efforts were unpopular and were met with little success. The subsequent King Harald Greyhide, also a Christian, was known for destroying pagan temples but not for efforts to popularize Christianity. He was followed by the staunchly pagan Haakon Sigurdsson Jarl, who led a revival of paganism with the rebuilding of temples. When Harold I of Denmark attempted to force Christianity upon him around 975, Haakon broke his allegiance to Denmark. A Danish invasion force was defeated at the battle of Hjörungavágr in 986. In 995

When he arrived, Haakon Jarl was already facing a revolt, and Olaf Tryggvason could convince the rebels to accept him as their king.

'' suggests that Inge could not assume power directly, but had to dispose of yet another pagan king, Eric of Good Harvests. According to M. G. Larsson, the reason why the Swedish core provinces had coexistence between paganism and Christianity throughout the 11th century was because there was a general support for the transition towards the new religion.Larsson 2002, 160 However, the old pagan rites were important and central for legal processes and when someone questioned ancient practices, many newly Christianized Swedes could react strongly in support of paganism for a while. Larsson theorizes that, consequently, the vacillation between paganism and Christianity that is reported by the sagas and by Adam of Bremen was not very different from vacillations that appear in modern ideological shifts.

in 1000 AD to put the arbitration between them to Þorgeir Ljósvetningagoði, the leader of the pagan faction. He opted, after a day and a night of meditation, that the country should convert to Christianity as a whole, while pagan worship in private would continue to be tolerated.


Motives for conversion

Some conversions appear to have taken place for political and material gain, while others were for spiritual reasons. For instance, some may have simply wanted to take the rich gifts (such as a fine, white baptismal garment) that were being handed out by Frankish nobles, who acted as the baptismal candidates' sponsors, when they were baptized. In the case of King Harald Bluetooth of Denmark, for example, he only partially converted to the new faith (at least at first) to preserve his independence from the Germans, who posed an even greater threat at the time than the Franks had been prior to this. He also saw that Christianity had much to offer to his rule. It not only helped to exalt his status, but it also provided practical help. The Missionary bishops were literate, and those who had experience of the royal government in Germany or England had the potential to be valuable advisors. There was also an economic motive to convert as pagan kings were fascinated with Christian wealth. As a result, some chose to accept the new faith as a way to gain access to this wealth.


Cultural Impacts

As increasing numbers of Scandinavians converted to Christianity, syncretism became more apparent, and the lines between religion and culture became increasingly blurred. Many converted and sought to help the Catholic missionaries; in doing so they often used traditional means that were often associated with their religious past, leading to the integration of Christian and pagan cultural symbols throughout the years of conversion. For example, prior to the building of churches, converts sought to aid both their relatives and the work of the missionaries by erecting rune-stones. Originally associated with paganism, these later rune-stones, inscribed with Christian imagery, came to exemplify the flexibility that was required of both the native traditions and Christianity throughout mass conversion.

, who had remained pagan long after the conversion of their neighbours. Some Sámi remained unconverted until the 18th century.


Aftermath

A 2009 research article by Phil Zuckerman showed that Scandinavian countries such as Denmark and Sweden were among the least religious nations in the world; nevertheless, "many Danes and Swedes, for instance, will profess belief in 'something,' although not necessarily the God of the Bible." According to Zuckerman, historical developments of culture and religion in Denmark and Sweden were crucially informing factors in explaining the state of irreligiosity.
