One of the key events that led to the taking of the U.S. Embassy in Tehran was President Jimmy Carter's decision to admit the Shah of Iran to the United States for cancer treatments in October 1979. The Iranian students who seized the embassy suspected a plot to reinstate the Shah and end the revolution. This triggered a 444-day hostage crisis that culminated in a failed rescue attempt known as Operation Eagle Claw, resulting in the deaths of eight U.S. service members.
Following the revolution, Iran initially aimed for a democratic system based on Islamic values. Mehdi Bazargan and Abolhassan Bani Sadr, both advocates of Islamic democracy, were appointed as leaders. However, Ayatollah Khomeini and his hardliners opposed this liberal vision, leading to the isolation and removal of the provisional government.
