Norse pagan worship is the traditional religious rituals practiced by Norse pagans in Scandinavia in pre-Christian times, Christianity, during the conversion period, was referred to as "nýr sidr" (the new custom), the conversion period is speaking in regards to which titled event, that took place between the 8th and the 12th centuries, and the realms of Scandinavia proper, Denmark, Norway and Sweden, established their own Archdioceses, responsible directly to the Pope?
Christianization of Scandinavia The Christianization of Scandinavia took place between the 8th and the 12th centuries. The realms of Scandinavia proper, Denmark, Norway and Sweden, established their own Archdioceses, responsible directly to the Pope, in 1104, 1154 and 1164, respectively. The conversion to Christianity of the Scandinavian people required more time, since it took additional efforts to establish a network of churches. The Sami remained unconverted until the 18th century.
Historical Slavic religion Slavic religion, in its narrower sense, defines the religious beliefs, godlores and ritual practices of the Slavs before the formal Christianisation of their ruling elites under the influence of Byzantine Orthodox Christianity, beginning with the latter's official adoption in 988 CE by Vladimir of Kievan Rus'. The Christianisation of the Slavic peoples was, however, a slow and—in many cases—superficial phenomenon, especially in what is today Russia. Christianisation was vigorous in western and central parts of what is today Ukraine, as they were closer to the capital Kiev, but even there, popular resistance led by "volkhv"s, Pagan priests, recurred periodically for centuries. Many elements of the indigenous Slavic religion were officially incorporated into Slavic Christianity, and besides this, the worship of Slavic gods persisted in unofficial folk religion until modern times. Since the early 20th century, Slavic folk religion has undergone an organised reinvention and reincorporation in the movement of Slavic Native Faith (Rodnovery).
