The long goodbye to Scandinavian Paganism and the Christianization of three realms
Prior to Christianity, the lands of Denmark, Sweden, and Norway saw the worship of an amalgamation of deities known most widely as the Aesir and Vanir. The Aesir were the primary gods, ruled by the wise, one-eyed Odin, though the worship of the strong thunder god Thor rivalled him. The Vanir were fertility gods, as highly valued as the Aesir, later becoming a subclass within them. But by the 10 th century, Christianity had brought an end to their polytheistic worship, culminating in three new realms unified under one faith.

The Christianization of Scandinavia was a long and painful process, filled with blood, sweat, and war. Denmark was the most easily transformed, as the Viking raids slowly introduced the religion through the Christian wives and slaves brought back as war prizes. The Danes were often in contact with England and Normandy, allowing them continued exposure to the new religion via political avenues as well. Thus there was little struggle in assimilating the two faiths, and they were able to coexist under the individual decrees of the Danish tribal leaders. It was King Harald Bluetooth who most firmly began this assimilation in the 930s, his own baptism propelling the religion to the forefront of Danish culture, unifying the tribes under this religious flag. The canonization of Canute IV in the 12 th century, the Christian ruler of Denmark in the late 1000s, cemented Christianity as Denmark's official religion.

The earliest recordings of Christianity in Sweden were in the 700s, and in the 830s, Saint Ansgar, a monk on a mission to bring Christianity to Northern Europe, came to her shores to spread word of the new faith at the bid of the Swedish king. His church at Birka was highly rejected however, so it was not until Olof Skötkonung, the first Christian king of Sweden, agreed to a toleration of the two faiths in the late 900s that Christianity found a place in Swedish culture. He established the first episcopal center in Skara rather than near Uppsala in Uppland, as there is written documentation that the largest worship center to the Norse gods existed at Uppsala. There is scarce archaeological evidence of the great temple of Uppsala, recorded by Christian writer Adam of Bremen, however in light of Adam's writings, it is believed Skara was Olof's choice location in an attempt to avoid a war between the followers of the two faiths. It was King Inge in the 1080s who disregarded the risks of war and ended the sacrifices at Uppsala, ultimately serving as the moment of transition to Christianity in Sweden. Though the result of this instance was Inge's temporary exile by his brother, by the year 1130 Christianity gained a permanent stronghold in Sweden and spread to become the foremost religion in the land.

Norway was the most difficult to transform from polytheism to Christianity as its history was filled with rulers who constantly dictated the religion. The most conflict was seen during a fifty year period, 950-1000 CE, under King Haakon, a soft-handed pioneer of the Christian faith. Haakon's method was similar to Constantine's in the Byzantine Roman Empire, resulting in an attempt at a midway approach: temples were left to the pagans with churches built right beside them and though he refused on his own part to sacrifice to the Aesir and Vanir, he also refused to punish those who continued this practice. Haakon was able to begin the spread of Christianity throughout this region by showing kindness to the established polytheistic religion, enforcing the new while never exiling the old.
Unfortunately, King Haakon, like Bluetooth and Olof, was a rare sort during this period. Upon his death, Jarl (Earl) Haakon replaced him, himself a pagan man. All the Christianization that King Haakon had established was utterly destroyed and a heavier emphasis was placed on the existing Aesir and Vanir. In acting this way, not only did Jarl Haakon create a stricter war against Christianity but in the years to come, he forged a reason for the Norwegian Christians to detest the Aesir followers. With the end of the 10 th century, the Christian king Olaf Tryggvason was very much ready to eliminate what he believed were narrow-minded, hate-filled followers.
