The term "Arsacid" refers to the ruling dynasty of the ancient Persian Empire, specifically the Parthian Empire, which existed from around 247 BCE to 224 CE. Founded by Arsaces I, the dynasty played a crucial role in the political landscape of ancient Iran and was known for its conflicts with the Roman Empire. The Arsacid rulers were notable for their unique blend of Persian and Hellenistic cultures, which influenced art, architecture, and governance. The dynasty's legacy includes the establishment of a feudal system and the promotion of trade along the Silk Road, contributing to the cultural exchange between East and West.
