Article: In 1935, Reza Shah requested the international community to refer to the country by its native name, Iran. As the New York Times explained at the time, "At the suggestion of the Persian Legation in Berlin, the Tehran government, on the Persian New Year, Nowruz, March 21, 1935, substituted Iran for Persia as the official name of the country." Opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably. Today, both Persia and Iran are used in cultural contexts; although, Iran is the name used officially in political contexts.

Now answer this question: Who endorsed a move to use Persia and Iran interchangeably after opposition to the official name change?
Professor Ehsan Yarshater
