In, the first ruler of the
Sasanian dynasty,
Ardashir I (r. 224–242) after having conquered his native province,
Pars, invaded Meshan, killing its ruler, Bandu. Ardashir had a city named Karkh Meshan rebuilt, and had it renamed as Astarabad-Ardashir. According to a fragmentary
Manichean account found in
Turfan, Mihr-šāh, a brother of the Sasnian king
Shapur I (r. 240–270), ruled as the vassal-king of Meshan. According to this
Manichean account, Mihr-šāh was visited and converted by
Mani himself – some scholars, however, doubt the accuracy of this source. Ardashir also built (or rebuilt) a town named
Vahman-Ardashir, also known as Forat Meshan. A son of Shapur I,
Shapur Mishanshah, is confirmed to have ruled Meshan from an unknown date until his death in 260, and was probably succeeded by his wife
Denag. According to the inscription of king
Narseh (r. 293–302), known as the
Paikuli inscription, Meshan was ruled by an Iranian aristocrat named Adurfarrobay, who would later rebel against Narseh and support a claimant to the Sasanian throne,
Bahram III. During the 5th century, Vahman-Ardashir had seemingly succeeded Karkh Meshan as the capital of Meshan, due to its mention as the chief city of Meshan by
Syriac sources. The port of
Obolla (Apologos) was located in this province. ==Population==
