What happened
Mani, born around 216 CE in southern Mesopotamia and raised in a Judaeo-Christian Baptist community, founded a new religion he saw as completing the earlier revelations of Zoroaster, the Buddha, and Jesus. Under Shapur I, Mani enjoyed royal tolerance and spread his teaching freely, partly because the Zoroastrian priest Kartir had not yet gained enough influence to block him. Kartir served under Shapur I and rose to real power under Shapur's successors Hormizd I, Bahram I, and Bahram II, leaving several inscriptions, including at the Ka'ba-ye Zartosht, that describe his own religious career in the first person. Once Bahram I took the throne and aligned himself with Kartir, policy reversed. Mani was arrested and imprisoned on the king's orders, and according to the Encyclopaedia Iranica's review of the earliest sources, he was executed and his body hung up at a gate of the city, an event usually dated to around 274 CE, though some traditions place his death as late as 277 CE. Kartir's own inscription goes further, claiming he struck down and suppressed Jews, Buddhists, Hindus, Christians, Nazarenes, Baptists, and Manichaeans across the empire, and describing his campaign against the Jewish community as reaching a particular peak of severity. Modern scholars reading the same text disagree on how literally to take Kartir's boasts: some read certain measures against Jewish practice as the Magi asserting religious authority within Jewish communities rather than outright violence, but the specific case of Mani is not in dispute since multiple independent traditions, Manichaean, Christian, and Zoroastrian, confirm the execution.
Why it matters
This is the turn from the religious pluralism of Shapur I's court to a Sassanid state that treated Zoroastrian orthodoxy as bound up with imperial order and treated rival faiths as a threat to it. The persecution failed to kill Manichaeism itself, which spread further east into Central Asia and China and west into North Africa and the late Roman world, but inside Persia it confirmed Zoroastrianism's status as the empire's protected and enforced religion for the rest of the Sassanid period.
How we know
Kartir's own inscriptions are primary sources carved in his lifetime, though as self-authored monuments they present his actions in the most flattering light and historians read his specific claims of persecution with some caution about self-promotion. Mani's execution is corroborated independently by Manichaean texts from Central Asia and hostile Christian polemical writing, alongside the Zoroastrian sources.
