What was name of Iran country in past?

The name "Iran" is a relatively recent name for the country, having been officially adopted in 1935. Before that, the country was known as Persia in the West, and as Irān or Airyanem Vaejah in Persian.

The name Persia is derived from the Greek name for the region, Persis, which was the name of a province in southwestern Iran that was home to the Persian Empire. The name Irān is derived from the Old Persian word ariyanam, which means "land of the Aryans". The term Aryan was used by the ancient Persians to refer to themselves and to other Indo-Iranian peoples.

The name Airyanem Vaejah is derived from the Avestan language, which was the language of the ancient Zoroastrian religion. Airyanem Vaejah means "land of the Aryans" or "land of the nobles".

The name Iran has been used to refer to the country since the 3rd century BC, but it was not until the 1930s that it became the official name of the country.
