Harald II of Denmark

Harald II of Denmark, also known as Harald Bluetooth, was a 10th-century king who unified parts of Denmark and Norway, helping to consolidate the Scandinavian region under a single rule. He is credited with introducing Christianity to Denmark, promoting cultural and political integration. Harald's reign marked significant shifts in religious and diplomatic practices, paving the way for stronger kingdom alliances. Historically, he is remembered for the Jelling Stones—large runestones that celebrate his achievements and conversion to Christianity, symbolizing the change from pagan beliefs to Christianity in Denmark.
