Olaf II of Norway was a monarch who ruled Norway from 1015 to 1028. Born in Ringerike around 995, he was the son of the petty king Harald Grenske. After converting to Christianity during his adulthood, he worked to spread the faith throughout Scandinavia. His reign ended following his death at the Battle of Stiklestad in 1030. He was later canonized and is remembered as a central figure in Norwegian national identity and a key proponent of the Christian faith in the region.
