The dates June 5 and 6, 1963, were significant in the history of the Iranian revolution. Masses of angry demonstrators from around the country took to the streets to protest against the arrest of a popular Shia cleric, Ayatollah Ruhollah Khomeini, an outspoken critic of the then king of Iran known as the Shah.
Although the protests were brought under control quickly, the Shah was left with no doubt as to the threat of the Shia opposition to his rule. The Shah also knew about the history of resistance among Shia clerics in Iran. A Shia-led tobacco revolt of 1891, against a tobacco concession granted by Nasir al-Din Shah to Great Britain, proved the effectiveness of the clerics in safeguarding public interests and curbing the excesses of the ruling monarchy.
As protests and strikes against the Shah continued in Tehran and elsewhere after 1963, hardliners within the regime advised the Shah to order the execution of Ayatollah Khomeini in order to bring the unrest to an end. Others argued that such a move would only exacerbate the anger of the devout Shia Muslims and would turn Khomeini into a martyr.
It was a senior diplomat, Hassan Pakravan, who eventually convinced the Shah to spare Khomeini's life. Pakravan, who met regularly with the Ayatollah when the Ayatollah was under house arrest, understood that the killing of an important Shia cleric would be regarded as an attack on Islam itself and, as such, would render the Shah ungodly and the enemy of the common people.
So, Khomeini escaped execution and having spent more than 15 years in exile, returned to Iran as a triumphant leader of the Iranian revolution on February 1, 1979, the same year Time magazine named him "man of the year".
