Tan-ShapurTan-Shapur was a Sasanian nobleman who served as Marzban of Persian Armenia from 552/554 to 560.BiographyLittle is known about Tan-Shapur. René Grousset said he governed Persian Armenia from 554 to 560. Cyril Toumanoff, however, says that Tan-Shapur's governorship of Persian Armenia lasted from 552 to 560. Stepanos Asoghik, an Armenian historian who lived in the 11th century, said that Tan-Shapur went proselytizing Zoroastrianism in Persian Armenia, where many Christians preferred to die instead of converting. However, it was during his governorship that the Armenian [Apostolic Church] organized the Second Council of Dvin. In 560, Tan-Shapur was replaced by Varazdat as Marzban of Persian Armenia.
