Sweden required a little more time to transition to Christianity, with indigenous religious practices commonly held in localized communities well until the end of the eleventh century. A brief Swedish civil war ensued in 1066 primarily reflecting the divisions between practitioners of indigenous religions and advocates of Christianity; by the mid-twelfth century, the Christian faction appeared to have triumphed; the once resistant center of Uppsala became the seat of the Swedish Archbishop in 1164. The Christianization of Scandinavia occurred nearly simultaneously with the end of the Viking era. The adoption of Christianity is believed to have aided in the absorption of Viking communities into the greater religious and cultural framework of the European continent.
