The homeland Vikings were comprised of small or 'petty' autonomous kings, who would raid other homeland kings , even when such clans put differences aside to form large fleets of longships for mutual benefit ..so they could go in great force to raid, trade and settle in distant and foreign lands , such kings would still act autonomously.
The allure of cHristianity [for Vikings leaders] was that it was seen as a way of uniting the clans like never before.
Christianity facilitated the ultimate agenda of wanting to consolidate power , by wielding control over the clans.
Leif Erikson was converted to christianity by king Olaf of Norway, and being made a member of the kings court, was commissioned the task of evagelizing and spreading it.
Harald Hardrada [the son King Olaf], was a catholic, but was no less ruthlessly ambitious, blood thirsty and barbaric than the pagan raider Vikings that came before him.
