Answer:
Step-by-step explanation:
The 1979 revolution, which brought together Iranians from many different social groups, has its roots in Iran's long history. These groups, which included clergy, landowners, intellectuals, and merchants, had previously united in the Constitutional Revolution of 1905-11. However, efforts toward successful reform were continually stifled, amid resurgent social tensions and foreign intervention by Russia, the United Kingdom, and, later, the United States. The United Kingdom helped Reza Shah Pahlavi establish a monarchy in 1921. Together with Russia, the United Kingdom then pushed Reza Shah into exile in 1941, and his son Mohammad Reza Pahlavi took the throne. In 1953, in the midst of a power struggle between Mohammed Reza Shah and Prime Minister Mohammad Mosaddegh, the United States Central Intelligence Agency (CIA) and the United Kingdom Secret Intelligence Service (MI6) orchestrated a coup. against the Mosaddegh government.
