Olaf Tryggvason, the posthumous son of a petty king and an alleged grandson of Harald Finehair, Norway’s first king, has acquired fame and wealth as a Viking leader.

Already a baptized Christian, he is at twenty-six in 994 confirmed as Christian in a ceremony at Andover; King Ethelred stands as his sponsor.

After receiving gifts, Olaf promises "that he would never come back to England in hostility."

Olaf leaves England for Norway and, indeed, is never to return, though "other component parts of the Viking force appear to have decided to stay in England, for it is apparent from the treaty that some had chosen to enter into King Æthelred's service as mercenaries, based presumably on the Isle of Wight."
