Question: 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?

<P0-S0> Vikings (Old English: "wicing"—"pirate", Danish and Bokmål: "vikinger" ; Swedish and Nynorsk: "vikingar" ; Icelandic: "víkingar" , from Old Norse "víkingar "), were Norse seafarers, mainly speaking the Old Norse language, who raided and traded from their Northern European homelands across wide areas of northern, central and eastern Europe, during the late 8th to late 11th centuries. <P0-S1>  The term is also commonly extended in modern English and other vernaculars to the inhabitants of Viking home communities during what has become known as the Viking Age. <P0-S2>  This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily. <SEP> <P1-S0> Norse pagan worship is the traditional religious rituals practiced by Norse pagans in Scandinavia in pre-Christian times. <P1-S1>  Norse paganism was a folk religion (as opposed to an organised religion), and its main purpose was the survival and regeneration of society. <P1-S2>  Therefore, the faith was decentralized and tied to the village and the family, although evidence exists of great national religious festivals. <P1-S3>  The leaders managed the faith on behalf of society; on a local level, the leader would have been the head of the family, and nationwide, the leader was the king. <P1-S4>  Pre-Christian Scandinavians had no word for religion in a modern sense. <P1-S5>  The closest counterpart is the word "sidr", meaning custom. <P1-S6>  This meant that Christianity, during the conversion period, was referred to as "nýr sidr" (the new custom) while paganism was called "forn sidr" (ancient custom). <P1-S7>  The centre of gravity of pre-Christian religion lay in religious practice — sacred acts, rituals and worship of the gods. <SEP> <P2-S0> In Germanic paganism, a vé (Old Norse) or wēoh (Old English) is a type of shrine or sacred enclosure. <P2-S1>  The term appears in skaldic poetry and in place names in Scandinavia (with the exception of Iceland), often in connection with a Norse pagan deity or a geographic feature. <P2-S2>  The name of the Norse god Vé refers to the practice. <P2-S3>  Andy Orchard says that a vé may have surrounded a temple or have been simply a marked, open place where worship occurred. <P2-S4>  Orchard points out that Tacitus, in his 1st century CE work "Germania", says that the Germanic peoples, unlike the Romans, "did not seek to contain their deities within temple walls." <SEP> <P3-S0>  The realms of Scandinavia proper, Denmark, Norway and Sweden, established their own Archdioceses, responsible directly to the Pope, in 1104, 1154 and 1164, respectively. <P3-S1>  The conversion to Christianity of the Scandinavian people required more time, since it took additional efforts to establish a network of churches. <P3-S2>  The Sami remained unconverted until the 18th century. <P3-S3> The Christianization of Scandinavia took place between the 8th and the 12th centuries.
