How did the royal power in Rome differ from the power of the pharaoh in ancient Egypt?

In ancient Rome, the power of the king was somewhat limited, moreover, his personality was not deified. In ancient Egypt, the ruler was practically a living god, whose power was unlimited, that is, the entire Egyptian people were his servant. In addition, the Egyptian rulers prepared very carefully for the afterlife. They believed that after death they would continue their lives in another world. Thus, they built themselves large tombs.
