Answer
**Answer: Short-lived** Harald Bluetooth's rule in Norway was indeed short-lived. After conquering Norway and becoming its king in the late 10th century, he faced rebellions and resistance from the Norwegian nobility and the local population, leading to a period of instability and conflict. His reign over Norway was eventually brought to an end as he lost control of the country to his son, Svein Forkbeard, around the year 1000.
