Few month before Iran’s anti-monarchy revolution, on September 8, 1978, in order to confront popular uprisings and keep its regime in power, the dictatorial Monarchy of Shah, massacred the defenseless and unarmed people in the streets of Tehran. This day has been named 'The black or bloody Friday' ever since. This mass killing flared up the nation’s anger and accelerated the Shah’s regime’s overthrow. Despite a great number of Tehran’s people including women and even children were weltered in their blood in this brutal massacre, Khomeini, who was in Najaf at that time, remained silent in fear, and took no stance for four days and even didn’t send a message for the victims’ families. Nevertheless, the determined people continued their demonstrations and showed that they are not intimidated by Shah’s martial law and such a massacre. Khomeini once again took the opportunity and sent another message to the people after four days.
