Who did they free the Iran hostages?

The Iran hostages were freed on January 20, 1981, the day Ronald Reagan was inaugurated as President of the United States. The release followed prolonged negotiations between the U.S. and Iran, which were influenced by various factors, including the changing political landscape after the fall of the Shah and the onset of the Iran-Iraq War. The hostages had been held for 444 days at the U.S. Embassy in Tehran. The timing of their release was seen as a significant moment in U.S.-Iran relations.
