Anglo-Persian War - Origins

Origins

In the context of the Great Game—the Anglo–Russian contest for influence in Central Asia—the British wished for Afghanistan to remain an independent country friendly to Britain as a buffer against Russian expansion towards India. They opposed an extension of Persian influence in Afghanistan because of the perception that Persia was unduly influenced by the Russians. The Persians had repeatedly attempted to acquire Herat by force, most recently in 1838 and 1852; both times British opposition had convinced them to back down prior to war. They made a fresh attempt in 1856, and succeeded in taking the city on 25 October, with Russian encouragement and in violation of the existing Anglo-Persian treaty. In response, the British Governor-General in India, acting on orders from London, declared war on 1 November.

Separate from and in many ways prior to the dispute over Herat was an incident concerning one Meerza Hashem Khan, whom the British ambassador hoped to appoint as a secretary in the mission in Teheran. The Persians objected, creating a dispute that escalated when rumours appeared that the British ambassador had improper relations with the man's wife, who was the sister of the Shah's principal wife. The dispute escalated still further when the Persians arrested the woman; the British ambassador broke relations when they refused to release her. Indeed, the initial mobilisation of British forces began in response to this incident, although it is unlikely that the British would have gone beyond the occupation of one or two islands in the Persian Gulf had the issue of Herat not arisen.
