After the counter-revolution the majority of Iranians have decided that they have had enough with Islam and want to return to their Zoroastrian roots. After the neo-Zoroastrians (they prefer to be called noZis) wrest back control, one of their first shock findings is that the birthplace of Zoroaster happens to be under the Naqsh-e Jahan square in Isfahan.
The noZis tear down the square and leave the rubble while they decide what to do with the site. In the interim all the medieval Muslim sites, which form the bulk of the architectural legacy of Iran, are benignly (or rather callously) neglected in favour of Persepolis (which is garishly rebuilt in what the noZis think was Darius’s court) and other “reconstructed” Sassanian/Achamenian sites (many mosques have been discovered to have been built on top of fire temples).
Ferdowsi is the only Muslim poet truly privileged in noZi Iran but even the Shahnameh is under threat because it’s written in the “alien Arabic script” and not in the purer Pahlavi script (in fact some noZis argue that there should be a switch to the more “Aryan” Latin alphabet). At any rate the majority of Iranians are back to being officially illiterate.
Modern Persian is deemed to have far too many Arabic words and so the more rustic Dari of Yazd is chosen as a base language. Considering that this Dari was spoken by insular villagers the last millennium; it’s deemed that Avestan is the only acceptable source language. Reality turns out to be a bit different; Old Persian in the Arabic script remains the dominant language of arts, calligraphy and culture while New Dari in Pahlavi becomes totally dependent on Anglo-French borrowings to become a complete language.
In the interim any Islamic poet, scientist or historian (even if Persian/Iranian) is sort of cast as the “other” and a scramble/obsession begins to discover ancient Persia’s scientific & aesthetic contributions. Some of Iran’s finest minds have been able to prove that ice cream in fact originated in Yazd.
Furthermore thousands and thousands of online noZis descend on the web to foam and obsess about Iran’s Muslim neighbours and to complain about Iran’s preferential treatment of her Muslim minority (they still maintain their own separate laws to the chagrin of the noZis).
They are also fuming at Eastern Iran’s still heavily Muslim region decision to secede into a new Khorasani state with Mashad & Herat as the capital. Iranian nationalists draw maps of Greater Iran that prominently figure Khorasan and constantly remind the Khorasanis that their Islamic identity is a myth and in fact they were Zoroastrians just a few generations back.
