The Viking Age marked the end of Denmark's prehistoric period in the early 9th century. As the Viking era began, the Danish people emerged as formidable explorers, traders, and warriors who played a central role in shaping European history from the 8th to 11th centuries. Their seafaring skills, advanced shipbuilding, and navigation techniques enabled them to explore, raid, and establish settlements across vast regions.

In the 9th century, Danish Vikings ventured from the Faroe Islands to discover and settle in Iceland. From there, they expanded to Greenland and later reached the shores of Vinland, believed to be modern-day Newfoundland. The Danish Vikings also excelled in long-distance trading, using intricate networks that stretched from Greenland in the north to Constantinople in the south, navigating through rivers like the Dnieper, and establishing connections through the Kievan Rus, a state founded by Viking rulers.

The Danish Vikings' influence was particularly strong in the British Isles. In the late 9th century, they began their incursions, significantly impacting the Anglo-Saxon kingdoms. By the time they established the Danelaw, the Danes had conquered most of northeastern England, imposing Danish laws and customs. Only the Kingdom of Wessex, led by Alfred the Great, resisted their advances. Following a series of fierce battles, Alfred emerged as the sole remaining English king, setting the foundation for a unified England.
Further south, Danish Vikings encountered the expanding Frankish Empire under Charlemagne. The earliest recorded mention of the Danes appears in Frankish chronicles, such as those by Notker of St Gall, who described King Gudfred’s interactions with the Franks in 804 CE. By 808 CE, King Gudfred launched a successful attack on the Obotrites, capturing the city of Reric and relocating its population to the trading hub of Hedeby. Despite efforts to negotiate peace with Charlemagne in 809 CE, tensions escalated, leading King Gudfred to launch raids against the Frisians with a fleet of 200 ships.
The Danish Vikings also raided and settled along the coasts of France and the Netherlands, launching large-scale attacks throughout the 9th and 10th centuries. They laid siege to Paris and devastated the Loire Valley. To manage these incursions, the Frankish rulers granted a group of Danes the right to settle in northwestern France on the condition that they defend the area from future Viking raids. This settlement evolved into the region known as Normandy, and it was the descendants of these Vikings who famously conquered England in 1066 under William the Conqueror.
The legacy of the Danish Vikings is evident in the fortified towns they established, such as Aros (modern-day Aarhus), and the impressive burial sites like the Ladby ship. Their activities left a lasting impact on European history, contributing to the political and cultural landscape that would define the medieval period.
