Our father among the saints Ansgar, Apostle of the North and Enlightener of Denmark (also Anskar or Oscar), (September 8(?), 801 - February 3, 865) was archbishop of Hamburg-Bremen. His feast day is February 3.
Ansgar was born in Amiens. He had for a period resided with the baptized Danish king Harald Klak, and when Louis the Pious at Worms in 829 was requested by two representatives from Sweden and the Swedish king Björn at Hauge, he appointed Ansgar missionary. The representatives had claimed that the several Swedes were willing to convert to Christianity. Ansgar arrived at Birka in 829, with his aide friar Witmar, and a small congregation was formed in 831, which included the king's own steward Hergeir as the most prominent member. The see of Hamburg was designated a "Mission to bring Christianity to the North," and thus St. Ansgar became known as the Apostle of the North.
A statue dedicated to him stands in Hamburg as well as a stone cross at Birka.
