Philip (in Greek Φιλιππoς; died 326 BC), son of Machatas, was an officer in the service of Alexander the Great, who was appointed by him in 327 BC satrap of India, including the provinces westward of the Hydaspes, as far south as the junction of the Indus with the Acesines.1 After the conquest of the Malli and Oxydracae, these tribes also were added to his government.2

Philip was put in charge by Alexander of building the city of Alexandria on the Indus.

The territory south of the junction of the Indus with the Acesines to the sea was given to Oxyartes and Peithon, son of Agenor (Arrian, Anabasis of Alexander VI.15.4)

Droysen considers this Philip to have been the father of Antigonus, the king of Asia. It is certain at least that they were both of the race of the princes of Elimiotis.

After the departure of Alexander from India, Philip was assassinated by a conspiracy formed among the mercenary troops under his command, 326 BC.3 Alexander named Eudamus and Taxilas as rulers of his territories in replacement:

"Alexander dispatched letters to India to Eudamus and Taxilas telling them to take charge of the district formerly under Philip, until he himself sent a satrap to govern it." (Arrian, Anabasis of Alexander, VI.27.2)

Philip

Philip (in Greek Φιλιππoς; died 318 BC) was satrap of Sogdiana, to which government he was first appointed by Alexander the Great himself in 327 BC. He retained his post, as did most of the satraps of the more remote provinces, in the arrangements which followed the death of the king (323 BC); but in the subsequent partition at Triparadisus, 321 BC, he was assigned the government of Parthia instead. Here he remained until 318 BC, when Peithon, who was then seeking to establish his power over all the provinces of the East, made himself master of Parthia, and put Philip to death.
