Relations between Britain and Iran were further exacerbated by an imbroglio with the British Minister to Iran, Mr. Murray, who left Tehran in high dudgeon. Mīrzā Āqā Khan turned his attention to Herat where (1855) a new opportunity to reestablish Iranian control presented itself. Grasping the opportunity, the Shah sent an army do Afghanistan. In October, 1856, Herat fell to the Iranians. In response Britain began the Anglo-Persian war (q.v.) which resulted in Iran’s quick defeat and the conclusion of the peace treaty of Paris in 1857, by which Iran finally gave up its claim to Afghanistan.
