FAQ

Are the Danes the same as the Vikings?

Viking raiders included Danish men. Not all Danish people were Vikings since Vikings were raiders; instead, most were farmers. The Viking age eventually came to an end in the Medieval Era.

What are some major events in Denmark's history?

Denmark converted to Christianity in the second half of the 900s under King Harald Bluetooth. In 1814, it lost control of Norway after hundreds of years of rule.

Denmark is a country located in northern Europe. In particular, Denmark covers a peninsula, Jutland, that juts into the North Sea and a neighboring archipelago stretching to the east. Denmark has long-standing cultural and historical connections to the other Scandinavian countries of Norway and Sweden. Throughout the history of Denmark, these countries have been united, while, at other times, they have fought wars against each other.

Denmark was likely first inhabited by humans about 12,000 BCE. These early people were nomadic hunter-gatherers who came from the southwest. For thousands of years, these ancient peoples developed stone tools before making bronze and iron tools, and they eventually worked in agriculture.

Due to their geographic position beside the North Sea, the Danish people developed a culture of seafaring and trading. Besides commerce, Danish and other Scandinavian peoples engaged in raiding expeditions all along the coast of Europe. These raiders, called Vikings, became synonymous with the Danish people; many today refer to medieval Scandinavian people as Vikings. Raids by Vikings occurred as far as Greece and deep into Russia. The earliest Russian state, Kievan Rus', was founded in part by Viking raiders and settlers called the Varangians. Likewise, Viking raiders and Danish settlers took control of northern France, creating Normandy. Norman knights later went on take control of southern Italy too.

Danish and Norwegian seafarers also settled in distant lands, including Iceland. The first major Scandinavian settlement in Iceland dates back to 874 CE. From Iceland, Scandinavian people sailed northeast to Greenland, settling there in the 980s. Most notable was an Icelander named Leif Erikson, who arrived in North America with other settlers sometime around 1000 CE. However, the Greenland and North America (or Vinland) colonies did not last long.

The Middle Ages marked the first unified Danish state. In the first half of the 900s, the various Danish tribes were incorporated into the Kingdom of Denmark, headed by King Gorm. Historians are unsure how unified this Medieval kingdom was. In the second half of the 900s, Gorm's son, Harald Gormsson, nicknamed Bluetooth, took the throne and cemented the kingdom's unity. Alongside taking Norway and other parts of Europe, Bluetooth introduced Christianity to Denmark. Since the reign of King Gormsson, Denmark has been a Christian country.

North Sea Empire

While the Kalmar Union fell apart, Denmark and Norway stayed together in a union until 1814. Over this period, however, Denmark-Norway faced significant challenges.

For one, Christian was being torn apart. Martin Luther, a German theologian, launched a campaign of criticism against the Catholic Church in the early 1500s. This inspired the Protestant Reformation, with new sects of Christianity rising. The kings of Denmark-Norway were sympathetic to persecuted Protestants and aimed to create greater autonomy from the church.

In 1533, the Protestant prince Christian III ascended to the throne. This event triggered a civil war between Catholic and Protestant forces, with King Christian winning after a few years. So, Denmark and Norway became Protestant countries, marking the beginning of the modern-day Lutheran Church of Denmark. Throughout the 1500s, Denmark fought wars against its neighbors, including Sweden and Poland, trying to resecure its power in the North Sea.

The Thirty Years' War and the Rise of Sweden

Soon, a religious war erupted across Europe: the Thirty Years' War, which began in 1618. In 1625, Denmark-Norway intervened in the conflict on the side of Protestant forces, fighting against the Habsburg dynasty, which ruled the Catholic Holy Roman Empire and Spain. In 1635, the war changed forms, with Denmark-Norway siding with the Habsburg Empire against Sweden and France. Ultimately the war ended in 1648, with Sweden gaining control of additional lands from Denmark-Norway.

In 1655, the ascendant Swedish Empire invaded Poland. In 1657, Denmark-Norway intervened on the side of Poland, hoping to get revenge against Sweden; this proved to be a disaster. Denmark lost more land to Sweden, though it did manage to repel a Swedish attack on the Danish capital, Copenhagen.

In response to these humiliating defeats, Denmark passed government reforms that granted greater power to the king at the cost of the Danish noblemen. These absolutist reforms were designed to strengthen the country against Sweden.

While Denmark-Norway was in a precarious position in Europe, it also sponsored colonial expeditions to distant lands, including Iceland, Greenland, and the West Indies, as well as commercial expeditions to Africa and India. These overseas territories were never as large as their contemporary rivals, however.

The history of Denmark has shaped the country today. While not a large country (it has a population of roughly 5.9 million), Denmark today is prosperous and thriving. It is a member of the European Union, an economic and political alliance across much of Europe. However, Denmark opted out of using the currency of the European Union, the euro, in a 2000 referendum. Denmark also joined the North Atlantic Treaty Organization, a defensive alliance with the United States and other democratic countries, in 1949.

Denmark is a Scandinavian country in northern Europe. The Danish tribes were united in the first half of the 900s by King Gorm. His son, Harald ''Bluetooth'' Gormsson, cemented the unity of Denmark and converted the kingdom to Christianity. Meanwhile, Viking raiders from Denmark attacked distant lands. Harald's son, Sweyn, ruled over England and Norway in the brief North Sea Empire. Later, Denmark, Norway, and Sweden were united in the Kalmar Union. This empire collapsed after the king perpetrated a massacre in 1520. Afterward, Denmark converted to Protestantism under King Christian III.
