The religion of ancient Egypt was so powerful that it dominated Egyptian culture. Most of the national wealth was devoted to the cult of the dead and the worship of the gods. Powerful priesthoods dominated daily life. Even the Pharaoh was the embodiment of the sun god. When the old religion no longer proved meaningful, a new religion, devoted to Isis and Osiris, took its place. Immortality and rewards for everybody stimulated popular enthusiasm. And the new cult spread far beyond the boundaries of Egypt.
