Babak Khorramdin
Babak Khorramdin was not well known outside academia until the 20th century; however, due to Soviet nation building efforts and Babak's following of teaching of Mazdak with its proto-socialist themes, Babak Khorramdin was proclaimed a national hero in the Azerbaijan Soviet Socialist Republic. For example, the Soviet era scholar Ziya Bunyadov, claimed that "Babak was a national hero of Azerbaijani people" while the Russian ethnologist, historian and anthropologist Victor Schnirelmann dismisses Bunyadov's theory, criticizing Bunyadov for not mentioning that Babak spoke Persian, and ignoring the witness accounts of Babak's contemporaries who call him Persian. To this day, in the modern Republic of Azerbaijan, Babak is a cult figure and celebrated as a national hero. In modern Iran, due to the rise of nationalism in the 20th century, and renewed interest in pre-Islamic Iran, Babak Khorramdin was rediscovered during the reign of Reza Shah, and is celebrated as a national hero. However, Babak remains a controversial figure in the Islamic Republic, whose idolization is criticized by some Shia clerics.
