Aryandes
Aryandes was the first Achaemenid satrap of ancient Egypt between the 6th and 5th centuries BCE, during the early 27th Dynasty of Egypt.Career
When king Cambyses II defeated pharaoh Psamtik III at the battle of Pelusium, Egypt became a satrapy of the Achaemenid empire, and Aryandes was appointed satrap shortly after. In 522 BCE, Aryandes was overthrown due to a revolt against the Achaemenid rule led by a native Egyptian pharaoh, Petubastis III. The rebellion was personally quelled by the new king Darius I during his expedition to Egypt in 518 BCE, and Aryandes reinstated. The satrap then attempted to subjugate Libya with poor results.
Around 496 BCE, Aryandes fell out of favour with Darius I and was deposed and replaced by Pherendates. The reason for this decision is unknown, with Herodotus and later Polyaenus claiming that the satrap started minting his own silver coinage, calling it aryandic in opposition of the golden, already existing daric, thus irritating the great king. This story is now considered unlikely, also because no aryandic has ever been found to date. It appears more likely that Darius had real concerns of a declaration of independence by Aryandes for his satrapy.
