When do you refer to someone as persian?

The term "Persian" typically refers to people who are from Iran or are of Iranian descent, particularly those who identify with the ethnic group that historically speaks the Persian language (Farsi) and shares cultural ties to the Persian Empire. It can also denote cultural aspects, such as art, literature, and traditions, that are rooted in Persian heritage. While all Iranians may not identify as Persian, the term is often used broadly in cultural contexts to represent the dominant ethnic group in Iran.
