In 245 BC,Andragoras, theSeleucid governor (satrap) ofParthia ("roughly westernKhurasan"^[1]) proclaimed independence from the Seleucids, when - following the death ofAntiochus II -Ptolemy III seized control of the Seleucid capital atAntioch, and "so left the future of the Seleucid dynasty for a moment in question."^[2]

Meanwhile, "a man calledArsaces, of Scythian or Bactrian^[a] origin, [was] elected leader of theParni tribes."^[3] Following the secession of Parthia from the Seleucid Empire and the resultant loss of Seleucid military support, Andragoras had difficulty in maintaining his borders, and about 238 BCE—under the command of "Arsaces and his brotherTiridates"^[3][4]—the Parni invaded^[5] Parthia and seized control of Astabene (Astawa), the northern region of that territory, the administrative capital of which was Kabuchan (Kuchan in the vulgate).

A short while later the Parni seized the rest of Parthia from Andragoras, killing him in the process.
