With the U.S. bombing of three nuclear sites in Iran, relations between the two countries have arguably reached one of the lowest points in modern times. But the bad blood between the two countries isn’t new: The U.S. and Iran have been in conflict for decades – at least since the U.S. helped overthrow a democracy-minded prime minister, Mohammed Mossadegh, in August 1953. The U.S. then supported the long, repressive reign of the Shah of Iran, whose security services brutalized Iranian citizens for decades.

The two countries have been particularly hostile to each other since Iranian students took over the U.S. Embassy in Tehran in November 1979, resulting in economic sanctions and the severing of formal diplomatic relations between the nations.

Since 1984, the U.S. State Department has listed Iran as a “state sponsor of terrorism,” alleging the Iranian government provides terrorists with training, money and weapons.

Some of the major events in U.S.-Iran relations highlight the differences between the nations’ views, but others arguably presented real opportunities for reconciliation.

1953: U.S. overthrows Mossadegh

In 1951, the Iranian Parliament chose a new prime minister, Mossadegh, who then led lawmakers to vote in favor of taking over the Anglo-Iranian Oil Company, expelling the company’s British owners and saying they wanted to turn oil profits into investments in the Iranian people. The U.S. feared disruption in the global oil supply and worried about Iran falling prey to Soviet influence. The British feared the loss of cheap Iranian oil.

President Dwight Eisenhower decided it was best for the U.S. and the U.K. to get rid of Mossadegh. Operation Ajax, a joint CIA-British operation, convinced the Shah of Iran, the country’s monarch, to dismiss Mossadegh and drive him from office by force. Mossadegh was replaced by a much more Western-friendly prime minister, handpicked by the CIA.

1979: Revolutionaries oust the shah, take hostages

After more than 25 years of relative stability in U.S.-Iran relations, the Iranian public had grown unhappy with the social and economic conditions that developed under the dictatorial rule of Shah Mohammad Reza Pahlavi.

Pahlavi enriched himself and used American aid to fund the military while many Iranians lived in poverty. Dissent was often violently quashed by SAVAK, the shah’s security service. In January 1979, the shah left Iran, ostensibly to seek cancer treatment. Two weeks later, Ayatollah Ruhollah Khomeini returned from exile in Iraq and led a drive to abolish the monarchy and proclaim an Islamic government.

In October 1979, President Jimmy Carter agreed to allow the shah to come to the U.S. to seek advanced medical treatment. Outraged Iranian students stormed the U.S. Embassy in Tehran on Nov. 4, taking 52 Americans hostage. That convinced Carter to sever U.S. diplomatic relations with Iran on April 7, 1980.

Two weeks later, the U.S. military launched a mission to rescue the hostages, but it failed, with aircraft crashes killing eight U.S. servicemembers.

The shah died in Egypt in July 1980, but the hostages weren’t released until Jan. 20, 1981, after 444 days of captivity.
