Questions which ask about the first kings always have to have a few waffle words as historians are picky.
Harald Fairhair was the first king of Norway. The date of the start of his reign is 872 CE when he defeated other local kings at the Battle of Hafrsfjord. But since his kindom wasn't quite te same as modern Norway and was divided among his sons at his death, many historians credit St. Olav, who reigned from 1015 CE, as the first king to have control over the entire country.
