Very confused while talking to a friend’s friend who is a Persian. I have googled it but not sure still. Is Persia part of Iran? Or is Iran part of Persia? Looks like Persia doesn’t exist as a country? Is it a wider region?
or is it that Iranians are muslim and Persians are Zoroastrians but live in the same region?
Are Iranian and Persian two distinct cultures or a subset, eg I have been to my local Iranian restaurant that had Persian food, like an Indian restaurant that serves Goan food?
