Q: Information:  - Gotarzes I ( Parthian :  Gtarz , Ancient Greek :  Gtarzs ) was the ruler of parts of the Parthian Empire from ca . 91 BC to 87 BC. He was the grandson of Phriapatius and came to power during the troubled times around the end of the reign of Mithridates II.

He seems to have regained the southern lands from the usurper , Sinatruces , by 88/87 BCE and forced him to flee to the Central Asian steppe , after which he soon died .  - Phriapatius or Priapatius , sometimes called Phriapites , was the king of the Parthian Empire from 185 BC to 170 BC. He was the grandson of Tiridates I (246211 BC), the brother of Arsaces I (250211 BC), the founder of the Parthian Empire.  - The Seleucid Empire ("Basileía tn Seleukidn") was a Hellenistic state ruled by the Seleucid dynasty, which existed from 312 BC to 63 BC; it was founded by Seleucus I Nicator following the division of the Macedonian empire vastly expanded by Alexander the Great. Seleucus received Babylonia and, from there, expanded his dominions to include much of Alexander's near eastern territories. At the height of its power, it included central Anatolia, Persia, the Levant, Mesopotamia, and what is now Kuwait, Afghanistan, and parts of Pakistan and Turkmenistan.  - Arsaces I ("Arshak") was the founder of the Arsacid dynasty of Parthia, and after whom all 30+ monarchs of the Arsacid empire officially named themselves. A celebrated descent from antiquity (the Bagratid "line") begins with Arsaces. Arsaces or Ashk has also given name to the city of Ashkabad.  - The Parthian Empire (247 BC  224 AD), also known as the Arsacid Empire, was a major Iranian political and cultural power in ancient Iran and Iraq. Its latter name comes from Arsaces I of Parthia who, as leader of the Parni tribe, founded it in the mid-3rd century BC when he conquered the region of Parthia in Iran's northeast, then a satrapy (province) in rebellion against the Seleucid Empire. Mithridates I of Parthia (r. "c". 171138 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to eastern Iran.
