Achaemenes (/əˈkɛməniːz/) (born 705 BC) was the eponymous apical ancestor of the Achaemenid dynasty of rulers from Persis.
Other than his role as apical ancestor, nothing is known of his life or actions. "It is quite possible that Achaemenes was only the mythical ancestor of the Persian royal house [, but] [i]f Achaemenes was a historical personage, he should have lived at the end of the 8th and the first quarter of the 7th century B.C."
(Modern Persian: هخامنش) Greek: Ἀχαιμένης (Achaiménēs), Latin Achaemenes ultimately derives from Old Persian Haxāmaniš (𐏃𐎧𐎠𐎶𐎴𐎡𐏁), as found together with Elamite Ha-ak-ka-man-nu-iš and Akkadian A-ḫa-ma-ni-iš-ʾ in the non-contemporaneous trilingual Behistun inscription of Darius I. The Old Persian proper name is traditionally derived from haxā- ( Sanskrit Sakha) "friend" and manah "thinking power", yielding "having a friend's mind." A more recent interpretation reads haxā- as "follower", giving "characterized by a follower's spirit."
The name Achaemenes and similar can mean:-
Achaemenes (Haxāmaniš) was the satrap of Egypt from 484 BC until his death in 460 BC, and a member of the Achaemenid dynasty.
According to Herodotus, he was a son of Persian king Darius I by his wife Atossa, and full brother of Xerxes I. Ctesias, who wrongly calls him Achaemenides, states that he was a son of Xerxes, rather than his brother.
After the first rebellion of Egypt, he was put in charge of the country by king Xerxes. He commanded the Persian fleet at the Battle of Salamis (480 BC), and was defeated and slain by Inarus, the leader of the second rebellion of Egypt, during the Battle of Pampremis (460/459 BC).
