The Great Heathen Army, also known as the Viking Great Army, was a coalition of Vikings, mainly Danes but including norseman from Norway and Sweden, who invaded England in 865. It sought to invade and conquer the four remaining kingdoms of the Heptarchy. The invasion and subsequent war with the kingdoms lasted from 865 until 878 with the Battle of Edington and founding of the Danelaw in Eastern England. 

Trivia

• According to the Sagas, the cause of the invasion and war was the killing of legendary Viking, Ragnar Lodbrok by Northumbrian King Ælla. 
  • This led Ragnar's sons, Ivar the Boneless, Bjorn Ironside, Ubba, Sigurd Snake-in-the-Eye, and Halfdan Ragnarsson to seek revenge.
• The Danelaw was granted to the Vikings by Alfred the Great on the condition that Viking commander Guthrum convert to Christianity.
