Valdemar II of Denmark

Valdemar II of Denmark, known as Valdemar the Conqueror, reigned as King of Denmark from the year twelve hundred and two until his death in twelve forty-one. His rule was marked by significant military conquests and territorial expansion, particularly through his invasion of Lybeck and Holstein in twelve oh seven, which greatly enlarged Danish lands.

In addition to his military endeavors, Valdemar played a crucial role in the Norwegian succession, which led to the second Bagler War. This conflict temporarily resolved the succession issues and established the Norwegian king's allegiance to Denmark, further solidifying Valdemar's influence in the region.

Valdemar's reign was not without challenges, as he faced disputes with the papacy regarding the appointments of the Prince-Archbishop of Bremen and the Bishop of Schleswig. His military campaigns extended into northern Germany and included the establishment of Danish rule in Estonia in the year twelve nineteen.

Under Valdemar's leadership, Denmark saw the introduction of a feudal system, which transformed the socio-political landscape of the kingdom. Additionally, he was instrumental in the creation of the Code of Jutland, a legal framework that would govern Denmark until the year sixteen eighty-three.
