Mani is not Iranian he was born in Babylon Iraq south of Baghdad... Iraq at that time was under Persian empire but Mani spoke Syriac Aramaic and his ethnicity is mesopotamian... thank you
Mani, born in Ctesiphon, the ancient Persian capital, was a Persian prophet who served Shapur I, the great Persian king. Iraq, on the other hand, is a relatively new country compared to the great Persia. At Mani's time, there was no country named Iraq, nor a country named Mesopotamia. I recommend studying basic history and geography... Thank you
