Works & Achievements
A major military victory that added Egypt to the Achaemenid Empire, making Persia the greatest power in the ancient world of the time.
By proclaiming himself pharaoh, Cambyses ushered in the first period of Persian rule over Egypt, which was incorporated as a satrapy of the empire.
Cambyses took on Egyptian royal titles and a coronation name (Mesutire), relying on local notables such as Udjahorresnet to govern.
Contrary to his reputation for impiety, inscriptions confirm that a sacred Apis bull was buried with full honors during his reign, a sign of a policy of religious conciliation.
The establishment of Persian control over the Nile Valley, paving the way for the system of satrapies that Darius I would later refine.
Attempts to extend the empire toward the Kingdom of Kush (Nubia) and the Oasis of Ammon, which ended in famously remembered failures.
Anecdotes
According to the Greek historian Herodotus, Cambyses II is said to have descended into madness after his conquest of Egypt, going so far as to stab the sacred Apis bull venerated by the Egyptians. Modern historians believe this legend was largely exaggerated by Egyptian priests hostile to the Persian conqueror, since inscriptions show, on the contrary, that an Apis bull was buried with full honors during his reign.
Herodotus recounts that an army of 50,000 men sent by Cambyses to attack the oasis of Ammon (Siwa) is said to have vanished entirely in the desert, swallowed up by a sandstorm. This “lost army of Cambyses” has become a famous enigma, and archaeologists have long searched for its traces in the Western Desert of Egypt.
To defeat the Egyptians at the Battle of Pelusium in 525 BC, a clever trick is reported: the Persian soldiers are said to have placed cats — sacred animals in Egypt — in front of their ranks, paralyzing the defenders, who dared not harm these revered creatures. The story illustrates the importance of sacred animals in Egyptian religion, even if it is probably embellished.
Cambyses died in 522 BC while returning from Egypt, under murky circumstances: according to Herodotus, he accidentally wounded himself in the thigh with his own sword while mounting his horse. His death without an heir opened a serious succession crisis, which was exploited by a usurper posing as his brother Bardiya.
To conquer Egypt, Cambyses negotiated the crucial help of the Phoenicians, whose fleet dominated the eastern Mediterranean, and secured the support of an Arab chieftain to cross the Sinai desert by ensuring his army's water supply. This preliminary diplomacy shows that his victory rested on more than military force alone.
