Ayatollah Khomeini was the religious leader of Iran from 1979 to 1989. In that time he implemented Sharia Law (Islamic religious law) with the Islamic dress code enforced for both men and women by Islamic Revolutionary Guards and other Islamic groups. Opposition to the religious rule of the clergy or Islam in general was often met with harsh punishments. In a talk at the Fayzieah School in Qom, August 30, 1979, Khomeini said:

“Those who are trying to bring corruption and destruction to our country in the name of democracy will be oppressed. They are worse than Bani-Ghorizeh Jews, and they must be hanged. We will oppress them by God’s order and God’s call to prayer.”

In the 1988 massacre of Iranian prisoners, following the People’s Mujahedin of Iran operation Forough-e Javidan against the Islamic Republic, Khomeini issued an order to judicial officials to judge every Iranian political prisoner and kill those who would not repent anti-regime activities. Many say that thousands were swiftly put to death inside the prisons. The suppressed memoirs of Grand Ayatollah Hossein-Ali Montazeri reportedly detail the execution of 30,000 political activists.
