Reza Shah's 1935 'Iran' Renaming Request and British Relations

SUMMARY

In March 1935, coinciding with Nowruz, Reza Shah Pahlavi formally requested that foreign governments and diplomatic missions refer to his country as 'Iran' instead of 'Persia'. This directive, communicated through the Ministry of Foreign Affairs, was reportedly aimed at asserting national sovereignty, reinforcing a broader historical identity, and supporting nationalistic goals. The term 'Persia' was derived from the Pars region and one ethnic group, while 'Iran' was an indigenous name used by its inhabitants for centuries. This semantic shift has been described as a bold assertion of identity with deep historical and political undertones.

The initial request appears to be well-documented by various historical accounts and web-based encyclopedic sources. However, specific records or scholarly works detailing the intricate diplomatic process and the precise reasons beyond general nationalistic aspirations, particularly how this nomenclature change directly impacted British diplomatic and commercial relations with the Anglo-Iranian Oil Company (AIOC), are not readily apparent in the provided sources.

STRONGEST CASE FOR

The renaming of Persia to Iran in 1935 was a strategic move by Reza Shah Pahlavi to modernize the nation, assert its sovereignty on the world stage, and unify its diverse ethnic groups under a single, historically resonant national identity. By explicitly requesting the international community use 'Iran,' the Shah aimed to shed a colonial-era designation and project an image of a powerful, self-determined state, which would naturally influence its dealings with foreign powers like Britain and major corporations such as AIOC.

STRONGEST CASE AGAINST

While the name change was a symbolic assertion of national identity, its direct impact on British diplomatic and commercial relations with AIOC might have been negligible or indirect. Geopolitical and economic factors, such as oil concessions, security interests, and the broader international political climate of the 1930s, likely held far greater sway over Anglo-Iranian relations than a change in nomenclature. The rebranding might have been more about internal domestic consolidation than a direct leverage point against external economic partners.
