Arsacids

Dynasty ruling the Parthian empire in Persia, founded by Arsaces I (r.c.247-c.211 BC). He was a king of the Iranian-speaking Parni peoples, who asserted the independence of Parthia from the Seleucids in 238 BC. His successors extended their rule over Persia and Mesopotamia, notably in the 2nd century BC. They emphasized continuity with the Achemenids but adopted Hellenistic culture. They were overthrown by the Sasanians in the 3rd century AD.
