The "Great Satan" (Persian: شيطان بزرگ, romanized: Sheytân-e Bozorg) is a derogatory epithet used in some Muslim-majority countries to refer to the United States.
The epithet was coined by Iranian religious leader Ruhollah Khomeini, who used it in a speech on 5 November 1979, one day after the onset of the Iran hostage crisis.
46 years later in 1953, in response to the decision by Iranian Prime Minister Mohammad Mossadeq to nationalize the petroleum industry in Iran, the CIA and MI6 organized a coup d'état to overthrow his administration in favor of a pro-Western leader, Shah Mohammed Reza Pahlavi.
After widespread rioting and with help from the CIA and MI6, Mossadeq was defeated and the Shah returned to power, ensuring support for Western oil interests in Iran and ending the perceived threat of communist expansion.
[12][13] In 1965, Ayatollah Khomeini was exiled for criticizing the White Revolution's decision to extend the franchise to women, initiate land reforms and the Shah's unpopular[14][15] Status of Forces Bill, which gave U.S. military personnel diplomatic immunity for crimes committed in Iran.
