The death of Harald III marked a significant turning point for Denmark. Harald III, who was a notable ruler known for his military campaigns and his attempts to consolidate power, died without a robust succession plan, creating a vacuum that could have resulted in unrest. However, Canute IV, otherwise known as Canute the Holy, emerged as his successor. Canute IV was the son of King Sweyn II and was known for his piety and strong adherence to the Christian faith; these traits would come to define his reign. In the wake of Harald's death, Canute IV aimed to solidify Denmark's position within the larger Christian realm in Europe and to fortify the church's influence in his kingdom.

Under Canute’s leadership, he sought to implement reforms that aligned with Christian doctrine, which also included the enhancement of church power. This focus not only aimed at stabilizing his rule but also establishing a lasting legacy associated with his commitment to Christianity, ultimately leading to his canonization years later. This period in Danish history is significant not only for its political shifts but also for the strengthened ties between the state and the church, which had lasting implications on Danish governance and society.

Canute IV's reign was also characterized by attempts to extend Danish influence beyond its traditional borders, particularly through engaging in alliances and military endeavors. His holy status posthumously raised his profile as a unifying figure for the people, and his efforts were instrumental in transforming Denmark into a more cohesive state under the banner of Christianity.
