The Vikings attacked and plundered because of envy—they wanted what their victims had. They believed that they did not have as much as others because their gods were not as powerful. This envy led to the introduction of Christianity into the Viking world. It was a time when groups of people converted together with their leaders. A personal relationship with Jesus Christ that resulted from a changed heart was a nonexistent concept. In the Viking’s world, the god to worship was often decided by the man left standing. There is debate over whether or not people believed the world was going to end at the close of the first millennium. There is little doubt that for Scandinavia, the end of the world as the Vikings knew it actually happened. Their pagan way of life ended and was replaced with a new Christian world.
