Sanatruces of Parthia

King Sanatruces of Parthia (also Sinatruces or Sanatruk, c. 157 BC – 70 BC) ruled the Parthian Empire from c. 93/2 BC to 88/87 BC during his first reign and c. 77 to 70 BC during his second reign. He was a member of the Arsacid house, who proclaimed himself king in Susiana and attempted to usurp the throne of Mithridates II. Ultimately, Gotarzes I forced him to flee to the Central Asian steppe. Years later, according to work attributed to Lucian, he regained the throne with the aid of the Sacaraucae Scythians or Saka, an Indo-European tribe akin to the Parthians who had invaded Iran in about 77 BC.

"Sinatroces, king of Parthia, was restored to his country in his eightieth year by the Sacauracian Scyths, assumed the throne and held it seven years." Makrobioi, 15.

He died c. 70 BC and was succeeded by his son Phraates III.
