Canonization
Because of his martyrdom and advocacy of the Church, Canute quickly began to be considered a saint. Under the reign of Olaf, Denmark suffered from crop failure, which was seen as divine retribution for the sacrilege killing of Canute. Miracles were soon reported as taking place at his grave, and his canonization was already being sought during the reign of Olaf.
On 19 April 1101, persuaded by the envoys from Eric III of Denmark, Pope Paschal II confirmed the "cult of Canute" that had arisen, and King Canute IV was canonized as a saint under the name San Canuto. He was the first Dane to be canonized. 19 January is recognised by the Catholic Church as his feast day. In Sweden and Finland he is historically, however, partially associated with St. Knut's Day, which in reality was celebrated in the memory of the death of his nephew, Canute Lavard.
In 1300, his remains and those of his brother Benedict were interred in Saint Canute's Cathedral, built in his honour, where his remains are on display.
