Drop of Iranian claim
Iran's parliament passed a bill in November 1957 declaring Bahrain to be the 14th province of Iran, with two empty seats allocated for its representatives. This action caused numerous problems for Iran in its international relations, especially with some United Nations bodies, Britain, Saudi Arabia, and a number of Arab countries. At this time, Britain set out to change the demographics of Bahrain. The policy of "deiranisation" consisted of importing a large number of different Arabs and others from British colonies as labourers.
In 1965 Britain began dialogue with Iran to determine their borders in the Persian Gulf. Before long extensive differences over borders and territory came to light, including the dispute over the dominion of Bahrain. The two were not able to determine the maritime borders between the northern and southern countries of the Persian Gulf. Eventually Iran and Britain agreed to put the matter of Dominion of Bahrain to international judgment and requested the United Nations General Secretary take on this responsibility.
Iran pressed hard for a referendum in Bahrain in the face of strong opposition from both the British and the Bahraini leaders. Their opposition was based on Al Khalifa's view that such a move would negate 150 years of their clan's rule in the country. In the end, as an alternative to the referendum, Iran and Britain agreed to request the United Nations conduct a survey in Bahrain that would determine the political future of the territory.
Report no. 9772 was submitted to the UN General Secretary and on 11 May 1970, the United Nations Security Council endorsed Winspeare's conclusion that an overwhelming majority of the people wished recognition of Bahrain's identity as a fully independent and sovereign state free to decide its own relations with other states. Both Britain and Iran accepted the report and brought their dispute to a close
