During his exile, Khomeini coordinated this upsurge of opposition—first from Iraq and after 1978 from France—demanding the shah’s abdication. In January 1979, in what was officially described as a “vacation,” the shah and his family fled Iran. The Regency Council established to run the country during the shah’s absence proved unable to function, and Prime Minister Shahpur Bakhtiar, hastily appointed by the shah before his departure, was incapable of effecting compromise with either his former National Front colleagues or Khomeini. Crowds in excess of one million demonstrated in Tehrān, proving the wide appeal of Khomeini, who arrived in Iran amid wild rejoicing on February 1. Ten days later, on February 11, Iran’s armed forces declared their neutrality, effectively ousting the shah’s regime. Bakhtiar went into hiding, eventually to find exile in France (Source: Britanica).
