Geography of Iran. When Persia became Iran. This article is a part of Persia or Iran by Professor Ehsan Yarshater, published in Iranian Studies, Vol. XXII, No.1, 1989. In 1935 the Iranian government requested those countries which it had diplomatic relations with, to call Persia Iran, which is the name of the country in Persian.
As Iran location map shows that Iran is located in western Asia. Countryâs name Iran is quite old and has been in use since the Sassanian era natively. However, the country was known to world by the name of Persia until 1935; but from the year 1935 the name Iran has internationally recognized. This is the reason that even in this modern era both names are used interchangeably.
