"The Parthians in whose hands the empire of the east now is, having divided the world, as it were, with the Romans, were originally exiles from Scythia. This is apparent from their very name; for in the Scythian language exiles are called Parthi. During the time of the Assyrians and Medes, they were the most obscure of all the people of the east. Subsequently, too, when the empire of the east was transferred from the Medes to the Persians, they were but as a herd without a name, and fell under the power of the stronger. At last they became subject to the Macedonians, when they conquered the east; so that it must seem wonderful to everyone, that they should have reached such a height of good fortune as to rule over those nations under whose sway they had been merely slaves. Being assailed by the Romans, also, in three wars, under the conduct of the greatest generals, and at the most flourishing period of the republic, they alone, of all nations, were not only a match for them, but came off victorious; though it may have been a greater glory to them, indeed, to have been able to rise amidst the Assyrian, Median, and Persian empires, so celebrated of o]d, and the most powerful dominion of Bactria, peopled with a thousand cities, than to have been victorious in war against a people that came from a distance; especially when they were continually harassed by severe wars with the Scythians and other neighboring nations, and pressed with various other formidable contests." - An ancient Roman account of the Parthians.

The Parthian people created an empire that lasted almost 500 years, from the mid-3rd century BCE until 224 CE, and it stretched from the Euphrates River in the west to Central Asia and the borders of Bactria in the east (Brosius 2010, 83).
