Why were Hardrada and Sweyn II fighting each other ?

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.

The reason was that Hardrada refused to relinquish Denmark to Sweyn II

Explanation:

Sweyn II was involved in a long battle with Magnus. When Magnus eventually died he gave Denmark to Sweyn and Norway to Hardrada. But Hardrada swore that he would not leave Denmark to Sweyn even though he had earlier collided with Hardrada to fight Magnus. That led to their fight.

The first time when Sweyn II would have captured Harald was when he came to Jutland and captured some slaves. But when he eventually threw the slaves overboard, Sweyn left him. Sweyn eventually won the fight.
