Kings of Denmark (The Kalmar Union)

Until the Treaty of Rae and the New Act of Union (both 1846) the various crowns of Denmark, Viken, Estonia, Pomerania, Lower Saxony and Rugia were all possessions of the Estridsson family though kept separate. After this date all territory was solely tied to the Crown of Denmark.

Danish kings are normally dated from Cnut I, those preceding are regarded as unhistorical or local kings at best.

Magnus I died in Autumn 1047 planning an invasion of Anglia. Cnut II's sister Estrid skillfully seized the treasury in Odense and pushed for her son Sweyn to be crowned quickly. The haste was seen as indecent by many contemporaries but it lasted. And so began the longest surviving ruling dynasty in the world.

=Viken=

Viken's kings and queens are normally dated from the break up of Harald Fairhair's Norwegian union.
