Numerous battles, revolts, and events have occurred during the Iranian Revolution. Above all, the three major key events that impacted the overall movement and change were Cinema Rex Fire, the exile of the Shah, and the collapse of the monarchy. Many present-day historians assume that some radical Islamic terrorism has influenced the terror rate in the United States or other countries. Especially, the Cinema Rex Fire was one of the deadliest terrorist attack in modern history. In August 1978, the Cinema Rex theater was locked by Shiite revolutionaries. As the revolutionaries began to set it on fire, the firefighters were late and hydrants were unable, the fire soon became a massive threat. The shrieks of the victims did not diminish since the helpless firefighters and police left the movie theater to be covered in flames. At least 377 people were burned alive and later the day of the deadly fire, their sympathizers marched on the street, shouting for the burn of the Shah (Byman, 1). As a result of continuous revolutionary attacks and protests, the Shah was forced to leave Iran and Iran formed a new leader with a new government. The security forces of the Shah killed thousands of protestants and democratic advocates, however, the more repressive the Shah became, alienated students and intellectuals declared for Khomeini’s return. A few months later, the protestants rioted and destroyed public buildings including banks and liquor stores. At the same time, Khomeini returned to Iran after fourteen years of his exile and the coup d’etat to the Shah’s security forces caused his regime to collapse and leave the country (History.com Staff, 1). Subsequently, after the Shah’s exile, the monarchy collapsed and the overthrow of Shah Mohammad Reza Pahlavi was successful. “Ayatollah Ruhollah Khomeini, arrested and sent away in 1964 for opposing Iran’s shah, triumphantly ended 15 years of exile from his homeland that day. Ten days later, the fall of the shah’s government was complete, and Iran was in the hands of conservative Islamic clerics. On Monday, Tehran begins 10 days of celebrations marking the 20th anniversary of the Islamic revolution’s stunning takeover of Iran, a country backed for decades by Western power and money” (CNN Reuters, 1). Before the final collapse, revolutionaries and rebel soldiers took over police stations and military installations near the palaces of the Pahlavi dynasty. Eventually, on February 11, 1979, the Supreme Military Council declared political peace and Khomeini overthrew the Shah, proclaiming Iran an Islamic Republic (Omnigraphics, 1).
