Olsok

Olsok (literally "Olaf's Wake" or "Olaf's Vigil" - that is the eve of St. Olaf's Day) is now the Norwegian name for 29 July, traditionally the date of the death of King Olaf II Haraldsson of Norway in the Battle of Stiklestad, east of Nidaros (Trondheim), Norway, in 1030. Olaf was canonised by Bishop Grimkell in Nidaros on 3 August 1031, and is remembered as Rex perpetuus Norvegiae, the Eternal King of Norway. More so than his attempts to finally (and forcefully) convert the country to Christianity, Olaf's martyrdom at Stiklestad appears to have contributed decisively to establishing the Church in all parts of the country.
