Reuter concession was a contract signed in 1872 between Baron Julius de Reuter (born Israel Beer Josaphat), a British banker and businessman, and Nasir al-Din Shah, Qajar king of Persia. The concession gave him control over Persian roads, telegraphs, mills, factories, extraction of resources, and other public works in exchange for a stipulated sum for 5 years and 60% of all the net revenue for 20 years. The concession was so immense that even imperialists like Lord Curzon characterized it as the most complete grant ever made of control of resources by any country to a foreigner. Local clergy were outraged by the concession and flyers were distributed in Tehran proclaiming that a Jew, Baron Reuter, will be in charge of country's affairs and that he plans to pass the railroad through the holy shrine in south Tehran. Clergy believed that this railroad plan is the work of Satan and will bring corruption to the Muslim lands. The concession was met with not only domestic outrage in the form of local protests but the Russian government was also hostile towards the concession as well. Under immense pressure, Nasir al-Din Shah consequently canceled the agreement despite his deteriorating financial situation. The concession cancellation was also due to British government refusing to support Reuter's unrealistic ambitions. While the concession lasted for approximately a year, the entire debacle set the foundation for the revolts against the tobacco concession in 1890 as it demonstrated that any attempt by a foreign power to infringe upon Iranian sovereignty would infuriate the local population as well as rival European powers, in this case the Russian government, who had their own interests in the region.
Reuter concession cancellation however resulted in the second Reuter concession which led to the formation of Imperial Bank of Persia by Baron Julius de Reuter.
