Iran–United Kingdom relations

Iran–United Kingdom relations are the bilateral relations between the United Kingdom and Iran. Iran, which was called Persia by the West before 1935, has had political relations with England since the late Ilkhanate period (13th century) when King Edward I of England sent Geoffrey of Langley to the Ilkhanid court to seek an alliance.

Until the early nineteenth century, Iran was a remote and legendary country for Britain, so much so that the European country never seriously established a diplomatic center, such as a consulate or embassy. By the middle of the nineteenth century, Iran grew in importance as a buffer state to the United Kingdom's dominion over India. Britain fostered conflict between Iran and Afghanistan as a means of forestalling an Afghan invasion of India. UK seeds a number of proximity conflicts between Iran and its neighbouring states like Azerbaijan on the countries' borders, Afghanistan on the Hirmand river and United Arab Emirates on possession of three disputed islands.
