The event that seriously hurt Jimmy Carter's presidency was failing to free American hostages in Iran. The Iran Hostage Crisis lasted from November 1979 to January 1981 and became a significant factor in undermining Carter's administration and contributing to his loss in the 1980 presidential election.
