The 1979 Islamic Revolution and the subsequent US Embassy hostage crisis solidified anti-American sentiment as a key pillar of Iran’s political identity.

After the Shah was overthrown, the revolutionary government led by Ayatollah Khomeini branded the US as the 'Great Satan' for its perceived interference and support of the Shah. The hostage crisis, where 52 Americans were held captive for 444 days, cemented deep mistrust and enmity. This event transformed political rhetoric into a lasting symbol of resistance against American influence.
