Afterwards, a Persian noble named Ardashir seized power by killing the Parthian king, and established the Sassanid empire along with the official state religion of Zoroastrianism, a polytheistic religion that had a creator (Ahuramazda) and a sun-god (Mithra). This religion was essentially limited to Persians. It made no attempt to convert others and it tolerated other religions in the region like Judaism. Its greatest king was Shapure II (A.D. 309-379), who beat back the weakening Romans and also extended Persian power towards China. This empire remained in control of Persia until Muslims took control of the region in A.D. 651.
