On February 11, 1979 the Iranian Revolution reached its final victory as the imperial armed forces declared their neutrality, the caretaker government of Prime Minister Shapour Bakhtiar collapsed, and Ayatollah Khomeini's revolutionary forces took control, ending the Pahlavi monarchy and clearing the way for the Islamic Republic. After the Shah left Iran on January 16, 1979 and Khomeini returned in triumph on February 1, two rival governments briefly coexisted: Bakhtiar's, appointed by the departed Shah, and the provisional government Khomeini named under Mehdi Bazargan. Street fighting broke out in early February between revolutionaries and forces loyal to the old order.
On February 11, 1979 the military high command declared the armed forces neutral and ordered troops back to barracks, effectively surrendering the country to the revolution. Revolutionaries seized government buildings, broadcast stations, and palaces; Bakhtiar fled into hiding and later exile. The date is commemorated in Iran as the revolution's victory.

Crowds in excess of one million demonstrated in Tehran as Khomeini arrived on February 1, and ten days later, on February 11, Iran's armed forces declared their neutrality, effectively ousting the shah's regime, after Prime Minister Shapur Bakhtiar had proved incapable of compromise with either his former National Front colleagues or Khomeini.
All military personnel were ordered back to their bases, effectively yielding control of the entire country to Khomeini, revolutionaries took over government buildings, TV and radio stations, and palaces of the Pahlavi dynasty, marking the end of the monarchy, and Bakhtiar escaped the palace under a hail of bullets, fleeing Iran in disguise.
The period from 1 to 11 February is celebrated every year in Iran as the Decade of Fajr, and 11 February is Islamic Revolution's Victory Day, a national holiday, with Bakhtiar later assassinated by an agent of the Islamic republic in 1991 in Paris.
Khomeini appointed Mehdi Bazargan as prime minister of an interim government while Bakhtiar insisted that he remained head of the only legitimate Iranian government, a standoff resolved on February 11 when the armed forces stood down.

Editorial Note
Paired record care: this February 11 record is the final victory of the Islamic Revolution and the collapse of the Bakhtiar government; the companion 1979-01-16 record is the Shah's departure, and the two are distinct dataset events marking the two decisive stages of the revolution. Coding note: the dataset labels this a popular revolt, accurately, as the last imperial government fell to a mass revolutionary movement when the armed forces declared neutrality; the fate is fled the country, referring to Bakhtiar, who escaped into hiding and then exile (and was assassinated in Paris in 1991, later context). Neutrality: this is among the most contested subjects in the dataset; the record confines itself to the documented sequence and attributes characterizations to their sources, avoiding partisan framing. Aftermath: an April 1, 1979 referendum established the Islamic Republic of Iran, a later dataset-adjacent event; February 11 is the officially commemorated victory day.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
