Bakhtiar becomes the last prime minister of Shah to save the country from plunging into an unwanted revolution. He was a political prisoner under the Shah but agreed to form a 'national unity' government. His cabinet lasts few months.
Shah left Tehran for the US in January 1979 and Khomeini entered Iran from exile in Feb 79. He delivered a speach to a large crowd in Tehran cemetery upon arrival (below!) Very soon the army declared indifference and the angry mob took over government offices and police stations. The revolution succeeded. Some say it was 'the inevitable'. Khomeini announces Bazargan (a liberal engineer) as the interim prime minister a few days later.
