Following World War II, nationalistic sentiments were on the rise in the Middle East, especially Iranian nationalism. AIOC and the pro-western Iranian government led by Prime Minister Ali Razmara initially resisted nationalist pressure to revise AIOC’s concession terms further in Iran’s favor. In May 1949, Britain offered a “supplemental oil agreement” to appease unrest in the country, but it did not satisfy Iranian nationalists since it did not give them the right to audit the AIOC’s books. On March 7, 1951, Prime Minister Haj Haj Ali Razmara was assassinated by the Fadayan-e Islam. Fadayan-e Islam supported the demands of the National Front, which held a minority of seats in Parliament, to nationalize the assets of the British Anglo-Iranian Oil Company.
