Norway / Sveinn Tjúguskegg (King Sweyn Forkbeard), first reign

Sweyn Forkbeard (Old Norse: Sveinn Tjúguskegg; Danish: Svend Tveskæg) was king of Denmark, England, and parts of Norway. His name appears as Swegen in the Anglo-Saxon Chronicle. He was the son of King Harald Bluetooth of Denmark, and the father of Cnut the Great.

In the mid-980s, Sweyn revolted against his father and seized the throne. Harald was driven into exile and died shortly afterwards in November 986 or 987. In 1000, with the allegiance of Trondejarl, Eric of Lade, Sweyn ruled most of Norway. In 1013, shortly before his death, he became the first Danish king of England after a long effort.
