Cappadocia (from Old Persian 𐎣𐎫𐎱𐎬𐎢𐎣 Katpatuka) was a satrapy (province) of the Achaemenid Empire located in Anatolia (modern-day Turkey).
The Satrapy belonged to the third tax district and paid an estimated 360 talents a year in tribute.
The first satrap (governor) known by name is Ariaramnes, who ruled sometime at the beginning of the reign of the Achaemenid king Darius the Great.
Datames (abridged from Datamithra) then became the satrap of southern Cappadocia; he led a revolt and was later assassinated in 362 BCE.
The last Achaemenid satrap of Cappadocia was Mithrobuzanes, who died in 334 BCE at the Battle of the Granicus fighting Alexander's invading army.
