Answer the following question: Information:  - 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.

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. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han Empire of China, became a center of trade and commerce.  - Mithridates III of Parthia ( Persian :   ) ruled the Parthian Empire c. 57 -- 54 BC.

Despite losing his Roman support , Mithridates advanced into Mesopotamia and managed to conquer Babylonia . He ousted Orodes and briefly restored his reign as king in 55 BC , minting coins in Seleucia until 54 BC. However , king Mithridates was besieged by Orodes ' general , Surena , in Seleucia , and after a prolonged resistance , offered battle to Orodes ' forces and was defeated . Mithridates was taken prisoner and executed in 54 BC by Orodes .  - 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.
