D'Arcy Oil Concession in Persia

In 1901, the Persian ruler Mozaffar ad-Din Shah Qajar granted the British financier William Knox D'Arcy an exclusive concession to search for petroleum across most of Persia. The agreement looks modest in hindsight, a speculative license signed by a cash-strapped monarchy, but it led to the first commercially significant oil discovery in the Middle East and to the creation of a company that would shape the region's politics for half a century.

Persia at the turn of the twentieth century was a weak state squeezed between British and Russian influence. The Qajar government was short of money and had already sold off economic privileges to foreigners, including a tobacco monopoly in the early 1890s that provoked widespread protest and was eventually cancelled. D'Arcy, an Englishman who had made a fortune in Australian gold mining, was persuaded by intermediaries to pursue oil rights in Persia, reportedly after hearing of surface seepages and earlier geological interest in the region. His agents negotiated with Persian officials in Tehran, helped by the government's need for funds.

The terms gave D'Arcy exclusive rights to prospect for and exploit oil, natural gas and related products over a vast area, excluding several northern provinces that fell within Russia's sphere of influence. In return, Persia received an initial payment in cash and shares, plus a promised royalty on future profits. The concession was set to last sixty years. Critics later argued that the share of revenue offered to Persia was small, though in 1901 nobody knew whether any oil would be found.

Exploration proved costly and frustrating. D'Arcy spent heavily over several years in difficult terrain, and by 1904 he was running short of capital. Support from the British Admiralty, which was interested in oil as fuel for a modernizing navy, and from the Burmah Oil Company helped keep the effort alive. In 1908 drillers struck oil at Masjed Soleyman in southwestern Persia, a find that is usually regarded as the beginning of the Middle Eastern oil industry. The Anglo-Persian Oil Company was founded in 1909 to exploit it, and the British government took a controlling stake in the company in 1914. The firm eventually became British Petroleum.

The legacy of the concession was long and contentious. Many Persians came to see the arrangement as emblematic of foreign exploitation, and resentment over royalties and British control fed nationalist politics through the 1930s and 1940s. This culminated in the nationalization of the industry under Prime Minister Mohammad Mosaddegh in 1951, and the crisis that followed. More broadly, D'Arcy's concession became a template for later oil agreements across the Gulf, in which Western firms secured long-term rights from local rulers in exchange for payments and royalties.
