Sinatruces of Parthia
Sinatruces was king of the Parthian Empire from to. Some sources indicate that he could have been a son of the Parthian ruler Mithridates I, and a half-brother of Phraates II. David Sellwood, historian, designates Sinatruces as a probably younger brother of Mithridates I. Sinatruces was succeeded by his son Phraates III.
Reign
The Parthian Empire had since the death of Mithridates II fallen into a state of turmoil and decline; the authority of the crown had decreased, while the empire lost lands to its neighbours. Sinatruces, who originally resided amongst the Saka of Central Asia, took advantage of the chaotic situation in the empire, and with the aid of the Saka captured the Parthian throne in, at the age of eighty. The name of the Arsacid branch established by Sinatruces on the Parthian throne has been coined by the modern historian Marek Jan Olbrycht as the "Sinatrucids", which ruled the Parthian Empire till 12 AD. The Sinatrucid family was notably supported by the Suren clan of Sakastan.During Sinatruces' reign, the Artaxiad king of Armenia, Tigranes the Great, took advantage of the weakness of the Parthians, and retook the "seventy valleys" he had previously ceded to Mithridates II, and also went to conquer the Parthian domains of Media Atropatene, Gordyene, Adiabene, Osroene, and northern Mesopotamia. Sinatruces died in 69 BC and was succeeded by his son Phraates III. Contemporary historian, Saghi Gazerani, has come up with the hypothesis that the story of the legendary Iranian monarch, Zav Tahmasp, contains echoes of the life of Sinatruces.
