Thor was the foremost of the gods to the common man, who could call upon him to ensure fertility, and widely worshipped. Hammer shaped amulets, a symbol of Thor because it was his weapon, were worn around the neck well into the Christianization of Scandinavia. There are molds from that time that contain both the cross and hammer shapes, side by side. His name occurs in numerous place names and it was his statue which was central in the great temple at Uppsala. He was associated by the Romans with Jupiter. Donar was an early version of Thor among the Germans. the Anglo-Saxons worshipped a thunder god named Thunor.
Thor has lived on, not as a part of any religion, but on our weekly calender. Thursday (Thor's Day) was derived from this mighty god."
So it took the penetrating power of the gospel of Jesus Christ to turn the hearts of the most feirce, warrior like people that Europe has ever known.
