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.

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

Another Sanatruces (Sanatrucius), the son of Mithridates IV, is mentioned as an ephemeral Parthian king in 115 AD by John Malalas, in his Chronographia.
