King Gorm the Old was a significant figure in early Danish history, ruling during the 10th century. He is often recognized as the first historically documented king of Denmark and is known for unifying various tribes under his rule. Gorm was a member of the House of Knýtlinga and is believed to have been a pagan, with his reign marking a transition towards Christianity in the region. Gorm's legacy is closely tied to his son, King Harald Bluetooth, who succeeded him and is credited with the Christianization of Denmark. Gorm the Old is also remembered for his burial site at Jelling, where the famous Jelling stones were erected, commemorating his reign and his family's significance in Danish history.
