Ansgar was the son of a noble
Frankish family, born near
Amiens (present-day France). After his mother's early death, Ansgar was brought up in
Benedictine monastery of
Corbie in
Picardy. His pupil, successor, and eventual biographer
Rimbert considered the visions (of which this was the first) to have been Ansgar's main life motivator. Ansgar acted in the context of the phase of
Christianization of
Saxony (present day
Northern Germany) begun by
Charlemagne and continued by Charlemagne's son and successor,
Louis the Pious. In 822, Ansgar became one of many missionaries sent to found the abbey of
Corvey (New Corbie) in
Westphalia, where he became a teacher and preacher. A group of monks, including Ansgar, were sent further north to
Jutland with the king
Harald Klak, who had received baptism during his exile. With Harald's downfall in 827 and Ansgar's companion Autbert having died, their school for the sons of courtiers closed, and Ansgar returned to Germany. Then in 829, after the Swedish king
Björn at Hauge requested missionaries for his
Swedes, King Louis sent Ansgar, now accompanied by friar Witmar from New Corbie as his assistant. Ansgar preached and made converts, particularly during six months at
Birka, on Lake
Mälaren, where the wealthy widow
Mor Frideborg extended hospitality. Ansgar organized a small congregation with her and the king's steward, Hergeir, as its most prominent members. In 831, Ansgar returned to Louis' court at
Worms and was appointed to the
Archbishopric of Hamburg-Bremen. This was a new archbishopric, incorporating the bishoprics of Bremen and
Verden and with the right to send missions into all the northern lands, as well as to consecrate bishops for them. Ansgar received the mission of evangelizing pagan
Denmark,
Norway and
Sweden. The King of Sweden decided to cast lots as to whether to admit the Christian missionaries into his kingdom. Ansgar recommended the issue to the care of God, and the lot was favourable. Ansgar did not forget the Swedish mission, and spent two years there in person (848–850), averting a threatened pagan reaction. In 854, Ansgar returned to Sweden when king
Olof ruled in Birka. According to Rimbert, he was well disposed to Christianity. On a Viking raid to
Apuole (current village in
Lithuania) in
Courland, the Swedes plundered the
Curonians. ==Death and legacy==
