Christian II became King of Denmark in 1513 and later King of Norway in 1514. His reign was characterized by a strong centralized authority, which often put him at odds with the influential Danish nobility. Christian's attempts to implement reforms, particularly regarding taxation and his support for the common people in opposition to the nobility, incited significant unrest among the aristocrats. His marriage to Isabella of Austria further strained relations as it shifted alliances within the Danish court. The nobility's dissatisfaction grew as economic challenges loomed, and resistance organized itself against his rule, exacerbated by a series of unpopular decisions. Tensions peaked with the escalation of rebellion against his reign, notably driven by the noble factions who opposed Christian's authority.

In the face of rising revolt, Christian II's position became increasingly precarious. He could not maintain the support of the nobility who previously had backed his ascent to the throne. In 1523, under pressure from mounting opposition, Christian fled Copenhagen, effectively signaling his abdication as the nobility reclaimed control. His departure not only marked the end of his reign but also initiated a power vacuum that would lead to increased noble influence in both Denmark and Norway. The subsequent rise of Frederik I, who succeeded Christian, set the stage for a new era of governance that favored aristocratic privileges over central monarchical power.

Christian II's forced abdication thus reshaped the political landscape of Scandinavia, illustrating the fragile nature of kingship in the face of entrenched aristocratic power. The fallout would influence royal authority dynamics in both Denmark and Norway for decades, contributing to the eventual rise of a more parliamentary-focused governance structure.
