Christianization of Scandinavia

The Christianization of Scandinavia, as well as other Nordic countries, took place between the 9th and the 12th centuries. During this time, the lands of Denmark, Norway, and Sweden began to follow the teachings of Christianity. Each of these countries set up their own church leaders, called archdioceses, who reported directly to the pope in 1104, 1154, and 1164.

The first signs of this change began in the 830s when a man named Ansgar built churches in places like Birka and Hedeby. Over the next couple of hundred years, kings in Scandinavia started to choose Christianity. This happened between 960 and 1020. These kings wanted to create churches, areas for church leaders, and show that their rule was based on Christian beliefs. They also tore down old temples that were used for other religions. Harald Bluetooth of Denmark was the first to say his country would follow Christianity around AD 965. He even put this message on a big stone called the Jelling Stones.

Historian Anders Winroth says that people in Scandinavia did not have Christianity forced on them by others. Instead, the kings chose Christianity because they thought it would help them rule better. Even though the kings and some people became Christian, it still took a long time for everyone to truly believe and follow Christian teachings, especially in some areas. During this time, the pope had not yet become the main leader of what is now called the Roman Catholic Church. This meant that different places could have their own versions of Christian practices.

Mission of Hamburg-Bremen

Missionary work in Denmark began with Willibrord, who traveled there between 710 and 718. Although he met with little success, he tried to teach some young men to help spread Christianity. Later, in 826, King Harald Klak of Jutland turned to Emperor Louis I of Germany for help and agreed to give up old beliefs in exchange for support. With him came Ansgar, a monk assigned to guide the new converts. Ansgar later traveled to Birka in Sweden and began a small Christian community there.

Over time, churches were built in places like Hedeby and Ribe. By 948, Ribe became the center of a new area for church leadership. Eventually, in 1103–04, an important church leadership center was created in Lund for all of Scandinavia.

Scandinavian countries

Denmark

Denmark's journey to Christianity happened in steps. Danes met Christians during their Viking raids from the 9th century to the 1060s. Local leaders decided whether their groups accepted Christianity. Over time, Danish kings and chiefs began to favor Christian allies, especially through political ties with places like Normandy, England, Ireland, France, and Germany.

Missionaries found unique ways to introduce Christianity. Instead of destroying old sacred spots, they built small chapels right where people already gathered, like at special meeting places or holy springs. This helped people feel comfortable with the new faith. Even after turning Christian, many Danes kept old traditions, like leaving offerings to local spirits, showing a mix of old and new beliefs.

Important Danish figures helped spread Christianity. King Gorm the Old started allowing Christians, and his son, King Harald Bluetooth, openly became Christian, which helped the religion grow. By the time of King Canute IV in the 11th century, Denmark was mostly Christian, though changes like new taxes caused some unrest.

Norway

Norway's shift to Christianity began with King Haakon the Good in the 10th century, but it took time. Later, King Olaf Tryggvason became a strong Christian leader after surviving a battle and deciding to change his ways. He worked hard to turn Norway and nearby areas like the Faroes, Orkney, Shetland, Iceland, and Greenland into Christian places.

After Olaf's death, some people went back to old traditions, but under King Saint Olaf, Christianity became stronger. By the 1150s, Norway set up its own church leadership, making Christianity the official religion.

Sweden

Sweden's change to Christianity started slowly. In the 800s, a missionary named Ansgar tried to start a church but didn’t get much support. Over time, more people in southern Sweden began to accept Christianity, especially around the year 1000.

King Olof Skötkonung, the first Christian king of Sweden, set up churches in places like Skara and Sigtuna. By the 1100s, an archdiocese was created in Uppsala, showing Sweden's official turn to Christianity. However, some areas, like Småland, needed extra efforts to fully accept the new faith.

Gotland

On the island of Gotland, old traditions were still important. Laws from the 1200s said that certain old practices could be punished, but change took time.

Jämtland

In the area of Jämtland, a man named Austmaðr is believed to have helped bring Christianity around the year 1030–1050, based on an old stone marker called the Frösö Runestone.

Other Nordic countries

The Scandinavian medieval kings also ruled over provinces outside of Scandinavia. These provinces are today known as the Nordic countries.

Faroe Islands

One of the first people from the Faroe Islands to become Christian was Sigmundur Brestisson. He brought Christianity to the Faroes because a king told him to. At first, he tried to tell the people about Christianity at a meeting, but they became very upset. Later, he went to a leader’s house at night with some armed men. He told the leader he must choose to accept Christianity or face serious trouble. The leader chose Christianity.

Finland

Evidence shows that Christianity began to appear in Finland during the 9th century. The Catholic church became stronger as Sweden’s influence grew in the 12th century. Finland stayed part of Sweden until the 19th century.

Iceland

Main article: Christianization of Iceland

Before Iceland was settled by Norse people in the 9th century, Irish monks called Papar were said to have lived there.

In the 10th century, after a king took Icelandic hostages, there were disagreements between Christian and non-Christian groups in Iceland. To avoid fights, leaders decided to let Þorgeir Ljósvetningagoði make the choice. After thinking for a day and a night, he decided the whole country should become Christian, but people could still practice their old beliefs privately if they wished.

Motives for conversion

People in Scandinavia started to believe in Christianity for different reasons. Some wanted to gain political power or wealth. For example, they might have been interested in the valuable gifts, like beautiful clothes, given during baptism ceremonies.

King Harald Bluetooth of Denmark chose to follow Christianity partly to stay independent from nearby German rulers, who were a bigger threat at the time. He also saw benefits in having Christian advisors who could help him govern and manage his kingdom better. Additionally, some leaders converted to Christianity because they were attracted to the wealth and resources associated with the Christian church.

Cultural impacts

As more people in Scandinavia started to follow Christianity, their old customs began to mix with the new religion. This mixing made it easier for everyone to adjust. Many people helped the Christian missionaries by using traditions from their past. One example is that before building churches, people put up rune-stones. At first, these stones were linked to older beliefs, but later they were carved with Christian symbols. This shows how both the old ways and the new faith worked together during this time of change.

In 1721, a new Danish–Norwegian colony began in Greenland with the goal of helping people learn about Christianity. Around this time, efforts also started in Norway and Sweden to help the Sámi people, who still followed their old beliefs long after others had changed. Some Sámi people still had not learned about Christianity until the 1700s.

Aftermath

Research from 2009 shows that countries like Denmark and Sweden are among the least religious places in the world. Many people there believe in "something," but not always in the Bible's idea of God. These countries' cultures and histories helped shape their views on religion today. Experts think that millions of people in Sweden, Norway, Finland, and Denmark do not strongly believe in a traditional religious view of God.
