The Parthians were people of Iranian origin who formed one of the most stable empires from mid 3rd century BC till 224 AD, when they were overthrown by the Sassanids. In 41 BC they conquered Syrian and Judea and nominated a king that was loyal to them from the the Hasmonean dynasty, but few years later the Romans took Judea back and put King Herod in charge who was not of the Hasmonean dynasty, but made sure they would never rule again.
The Pathian didn’t leave any written history. Most of what we know of them came from the writings of others and archaeology. Now, Kaveh F, et al. (2016) report preliminary findings in a new article that describes archaeological excavations in Pathian sites and attempts to tell the story of Pathian culture and beliefs through the excavated relics.
