The revolutionaries had done the unthinkable: they'd toppled the Shah's regime, ending 2,500 years of monarchy in Iran. And now, amidst the chaos, a charismatic cleric named Ayatollah Ruhollah Khomeini emerges as the champion of the Islamic Revolution. On December 3, 1979, he's officially declared the first Supreme Leader of Iran, marking a radical shift towards an Islamic republic. As Khomeini solidifies his grip on the country, the West watches anxiously, sensing a new era of tension in the Middle East.
