3. The 1979-81 U.S. Embassy Hostage Crisis
In November 1979, Iranian militants stormed the U.S. embassy in Tehran, capturing 52 American diplomats and citizens. They held them hostage for 444 days, demanding the extradition of the Shah, who was receiving medical treatment in the U.S. The crisis severely strained U.S.-Iran relations, leading to the severance of diplomatic ties and economic sanctions. The hostages were released on January 20, 1981, coinciding with President Ronald Reagan’s inauguration. This event remains a defining moment in the history of U.S.-Iran relations.
