Egyptian religion was polytheistic, which made it extremely flexible. Throughout Egypt's history beliefs and practices were constantly changing though the themes of fertility, rebirth, death and resurrection generally remained constant. The ancient Egyptians had a tendency to merge new beliefs with the old ones rather than simply replace them.

The Egyptians believed that there was a life after death. They thought that people had two important parts: a "ka", or life force that they only had while alive, and a "ba" which was more like a soul. If the "ka" and "ba" could be united in the afterworld the person would live in the afterlife. A key component was that the body be preserved for this to happen. This is why the Egyptians used the embalming process, or mummification, to preserve the dead. You had to earn your way into your afterlife by doing good deeds while you were alive. The more good deeds you did, the lighter your heart became.
Pharaohs. The heart of the dead was weighed in the presence of the jackal-headed Anubis, god of the dead, against a feather, representing Maat, goddess of truth. Balancing the scale meant immortality. Should the heart not balance perfectly, Amemet devoured it, and Seth, murderer of Osiris, ate the rest of the body.
Pharaohs were the king or Queen of Egypt. Most pharaohs were men but some well-known pharaohs, such as Nefertiti and Cleopatra, were women. A Pharaoh was the most important and powerful person in the kingdom. He was the head of the government and high priest of every temple.The people of Egypt considered the pharaoh to be a half-man, half-god. The Pharaoh owned all of Egypt. The Ancient Egyptians believed that their Pharaoh was the god Horus, son of Re, the sun god. When a pharaoh died he was believed to be united with the sun and then a new Horus ruled on earth.
