United States and Iran sign the Algiers Accords, January 19th, 1981
The agreement results in the freeing up of $7.9 billion in Iranian assets that had been frozen by the United States since the takeover of the American embassy in Tehran. Under the agreement, Iranian debts to US institutions will be paid, and the United States also promises not to intervene politically or militarily in Iranian internal affairs. The fifty-two Americans who worked in the embassy and had been taken hostage on November 4, 1979, will be set free and allowed to leave Iran.
