THE CHRISTIANIZATION OF THE NORTH

The end of Norse paganism was no battle but a century of pressure. The first missionaries, like Ansgar in Denmark around 826, preached almost in the desert. Real change came from above: kings discovered that one god and one church served to unify realms and legitimize crowns. Harald Bluetooth was baptized around 965 and carved it on the Jelling stone; Olaf Tryggvason imposed Christianity on Norway from 995, often by force; and Olaf Haraldson, fallen at Stiklestad in 1030, became Saint Olaf, martyr and eternal patron of Norway.

Each country kept its pace. Kingless Iceland voted conversion at the Althing around 1000 to avoid splitting in two. Sweden resisted longer: the pagan temple of Uppsala stayed active until King Inge the Elder destroyed it around 1087. Temples became churches (sometimes stone upon stone) and pagan cemeteries received crosses, but common folk took generations to abandon Thor and Freyr.

Most fascinating is the syncretism: for decades Thor's hammers and Christian crosses hung from the same necks, and goldsmith moulds cast both amulets at once, just in case. By 1100-1150 the north was officially Christian and the Viking Age, pagan by definition, had faded with it. The gods survived turned into weekdays, tales and, much later, movie superheroes.
