Cambyses II
Cambyses (Old Persian Kambujiya): son of Cyrus, second king of the ancient Persian empire (ruled 530-522).  In 525, he conquered Egypt (documented in the stela of Uzahor-Resenet). On his return home, he learned of the rebellion of Magian Gaumâta. Shortly afterwards, Cambyses died: according to the Greek researcher Herodotus, it was an accident caused by divine wrath, but the Behistun inscription suggests that he committed suicide.
