Occupation of Iran in World War 2

Eventually, collusion between the Tudeh and the Soviet Union brought further disintegration to Iran. In September 1944, while American companies were negotiating for oil concessions in Iran, the Soviets requested an oil concession in the five northern provinces. In December, however, the Majlis passed a law forbidding the government to discuss oil concessions before the end of the war, which led to fierce Soviet propaganda attacks on the government and agitation by the Tudeh in favour of a Soviet oil concession, while in 1945 the Azarbaijan Democratic Party, which had close links with the Tudeh, announced the establishment of an autonomous republic.
