The Persian people were now again to make their influence felt in the history of the world. Ardashir I destroyed the rule of the Arsacids in the winter of 226, and founded the illustrious dynasty of the Sassanids. Different from the Parthian rulers, who were northern Iranians following Mithraism and Zoroastrianism and speaking Pahlavi dialect, the Sassanids intensified nationalism and established a state-sponsored Zoroastrian church which often suppressed dissident factions and heterodox views. Under the Sassanids, Babylonia became the province of Asuristan, with its main city, Ctesiphon, becoming the capital of the Sassanid Empire.
