Ayatollah Khomeini, born on September 24, 1902, in Khomeyn, Iran, was a prominent Shiite Muslim cleric and the leader of the 1979 Iranian Revolution. He fiercely opposed the ruling Shah's secular regime, advocating for an Islamic government based on his interpretation of the Quran. Khomeini's charismatic leadership led to the overthrow of the Shah and the establishment of the Islamic Republic of Iran. Despite controversy and criticism, he remained a powerful figure until his death in 1989, leaving a lasting impact on Iran's political and religious landscape.
