Harald Bluetooth

About Harald Bluetooth

Harald Bluetooth was a pivotal Viking-era monarch, reigning as King of Denmark and Norway from approximately 958 until his death in 986. His HPI rank of #662 reflects his immense historical importance, primarily stemming from his role in uniting the disparate Danish tribes and consolidating his kingdom. Most notably, he is credited with Christianizing Denmark, a foundational shift that profoundly altered the course of Scandinavian history and laid the groundwork for the modern Danish state.

In the context of modern internet attention, Harald Bluetooth appears somewhat overlooked. He garners approximately 424K annualized Wikipedia views in 2025. This level of attention is roughly equal to his historical importance (an Attention Gap of ~1x), suggesting a baseline level of recognition. However, this modest figure stands in contrast to contemporaries or figures in similar fields; for instance, William the Conqueror, a contemporary, receives over seven times the attention with 3.0M views, despite a similar HPI ranking (#934).

The data suggests that while the gap is minimal, his interest is waning. His year-over-year change is down -13.3%, and his 2025 momentum shows a -16% drop between Q1 and Q3, indicating a slight, but measurable, cooling of public curiosity around this foundational Nordic ruler.
