Dynasty:

Cambysis II was one of the 1st kings in the 27th dynasty. He was from a Persian family.

History:

We don't have many Egyptians sources talking about that Persian invasion to Egypt. But Herodotus mentions that Cambysis was so cruel to the Egyptians and treated the priests of the temples and their gods badly and he even adds saying that he killed the Apis bull although there is other records mentioned the opposite. Cambyses II was son of Cyrus the Great, who had already named him as king of Babylon though Cambyses II resigned that position after only one year, invaded Egypt and successfully overthrew the native Egyptian pharaoh, Psamtek III, last ruler of the 26th dynasty to become the first ruler of the 27th Persian dynasty. His father had earlier attempted an invasion of Egypt against Psamtek III's predecessor, Amasis , but Cyrus' death in 529 BC put an end of that expedition.
