What was the importance of Osiris in Egyptian religion

Osiris has been mentioned many times, but not in any detail until now. Osiris played a very important role in ancient Egypt and this carried over into the rituals and beliefs of Egyptians much later, as well. It was because of the legend of Osiris that Egyptians believed they had the right to be transformed and to live in the afterlife. The myth of Osiris is like every other Egyptian myth: the story has changed with every political change of power.
