Answer:
Hardrada and Sweyn II fought one another over Denmark.
Sweyn II Estridsson was the King of Denmark from 1047 to 1076 which is the year he died.
On one occasion, Sweyn almost captured Harald Hardrada. Harald Hardrada had plundered Denmark and was making away with goods plundered and prisoners he had taken.
After a prolonged pursuit, Hardrada let go of the goods...then the prisoners. To rescue the men Hadrada had let go, Sweyn let Hardrada escape.
Sweyn II was a master at History and Geography. After his death, five of his sons succeeded him and managed the dynasty for 3 centuries.
