Why didn’t Iran keep the more appropriate historical name Persia?

 The decision to use the name "Iran" instead of "Persia" is rooted in the country's history and has political and cultural dimensions. The change in usage occurred in the 20th century. Here's a brief overview:

1. **Historical Context:**

   - "Persia" has been a historical and geographical term used to refer to the region that is now Iran. The name "Persia" became widely known in the Western world during the time of the Achaemenid Empire (550–330 BCE) and continued to be used for centuries.

2. **Name Change to Iran:**

   - In 1935, the Iranian government formally requested the international community to refer to the country as "Iran" instead of "Persia." This request aimed to emphasize the country's Persian identity while also acknowledging the existence of various ethnic groups within its borders.

3. **Cultural and National Identity:**

   - The shift from "Persia" to "Iran" was part of a broader movement in the early 20th century to promote a national identity that included various ethnic groups beyond the Persian majority. The term "Iran" is derived from "Aryan," emphasizing the country's historical connection to the Aryan people.

4. **Nationalistic Sentiments:**

   - Reza Shah, who was in power during the name change, sought to modernize and unify the country. The shift to "Iran" reflected a desire to emphasize a national identity that went beyond the historical Persian empire and included diverse ethnicities within the country.

5. **International Relations:**

   - The change in name was also seen as a way to assert Iran's independence and modernity in the international arena. "Iran" was viewed as a more neutral and inclusive term, avoiding associations with a particular historical period.

It's important to note that while "Iran" is the official name, the terms "Persia" and "Iran" are often used interchangeably, and both are historically and culturally significant. "Persia" is still commonly used in historical and cultural contexts, especially when referring to periods like the Achaemenid Empire or Persian literature and art. The decision to use "Iran" reflects the country's desire to emphasize a more inclusive national identity.
