According to Viking mythology, Valhalla was a great hall in the grandest palace of Odin,

king of the gods. The walls of Valhalla were gold, and its roof was made of battle shields.

Vikings believed that if they died heroically in battle, they would spend eternity fighting

and then feasting in Valhalla with Odin.

To make the voyage to Valhalla, a Viking hero needed a proper funeral. This included

being buried with his weapons, his clothing, and a ship. The servants of Viking warriors

were buried with them to serve their masters on the journey and beyond. Sometimes,

instead of being buried, the fully stocked ship was cast adrift and burned.

1. How might a Viking's beliefs about the afterlife affect his behavior in battle?

2. How is this belief system similar and also different from the ancient Egyptians?

The Vikings believed that dying a heroic death would help them reap the reward in the afterlife. This belief might have encouraged them to lead a courageous life. It might have made them more aggressive and belligerent towards their enemies and foes.

The Viking's and the Egyptian's both buried proper funerals for the dead ones. They also buried personal objects like clothes, crafts, etc along with the dead body. The difference between the Vikings and the Egyptians about the afterlife is the way how dead persons are rewarded or punished.
The Viking's simply believed that a heroic death would be eventually rewarded in the afterlife while the Egyptians believed that each person had to cross seven gates and would be finally judged on the seventh gate by the Gods.
