The Effects of the Iranian Revolution

The Iranian Revolution (1978-1979) was a turning point in Iran’s history and one of the most significant events in the modern Middle East. It led to the establishment of a new political order—one that many regard as one of the most dangerous dictatorial regimes in the world.

Today, Iran has influence beyond its borders, becoming a major architect and sponsor of terrorist organizations worldwide, responsible for hundreds of murders, exploitation of civilian infrastructure and armed conflicts around the world, from Argentina and the United States to Israel and India, as well as in many other countries. The terrorist network controlled by Iran is also one of the most powerful criminal networks around the globe, receiving money not just directly from Iran, but also from human, drug and weapons trafficking. 

Despite the sponsoring of international terrorism, the Iranian regime is engaged in the active repression and oppression of their own citizens; the number of killed, crippled and kidnapped Iranians has been growing ever since the establishment of the Islamic Republic of Iran in 1979. 

This timeline will follow key events in the formation of the current regime in Iran: 

In a series of protests and revolts culminating in the revolution under Khomeini's leadership, the Islamic Republic of Iran (IRI) was established on February 11, 1979. The new state—under Khomeini absolute control—was saturated with ultra-religious and anti-Western ideas. Khomeini actively promoted the idea that the country should be governed by Shiite theologians, proclaiming himself the ‘Supreme Leader’ of the country. 

The anti-Western propaganda worked, and on November 4, 1979, radicals seized the U.S. Embassy in Tehran. 66 embassy employees were held hostage by the Iranian regime for 444 days, only released after the signing of the Algiers Accords. 

The Iranian leadership authorized public rallies and parades to demonstrate its ideology. Thus, on August 7, the Iranian regime established the so-called ‘al-Quds Day’ (Jerusalem’s name in Arabic). As part of the new state holiday, anti-Western and anti-Israeli rallies and protests were held, where crowds chant ‘Death to America’ and ‘Death to Israel’.

In 1980, the Iranian regime began the cultural revolution—reforms aimed at introducing new ultra-religious and anti-western narratives. An important part of this process was the ‘islamization’ of universities—a reform of the education system based on Shiite-islamist ideas and values. As a result of islamization, more than 20,000 teachers were dismissed around Iran. 

On September 22, the Iran-Iraq War began—Iraq invaded Iran to eliminate its main rival for dominance in the region. The war lasted 8 years (September 22, 1980 - August 20, 1988), which made it one of the longest conflicts of the 20th century. During the war, both sides were noted for the use of chemical weapons, the use of child soldiers and attacks on civilian infrastructure, resulting in the deaths of tens of thousands of civilians in both countries.

In 1982, in the middle of the Lebanese Civil War, the Iranian regime orchestrated the formation of a new terrorist organization—Hezbollah, which would subsequently become Iran’s main proxy—and the most armed terrorist organization in the world. In parallel, in Iraq, where most of the population was Shiite, the Iranian regime supported the Badr Brigades to destabilize Iraq and help the spread of Iran’s ultra-islamist and radical Shiite agenda in the region.

The supreme spiritual, social, political and militant leader of the Islamic Republic and Revolution, Ruhollah Khomeini died on June 3, 1989. The next day, his closest ally, Ali Khamenei, became the new Supreme Leader of Iran, which he remains until today. 

In the early 1990s, the Iranian regime supported the nascent ‘Ansar Allah’ terrorist group in northern Yemen, which would later be known more commonly by the name of its founder—the Houthis. 

The consequences of the Iranian Revolution are still being felt today. Iran has continued to fund, arm, and direct militant groups across the region, fueling instability and conflict. Its long-standing enmity with Israel reached a new peak in 2024, when Iran launched a direct attack against the Israeli state using cruise and ballistic missiles. Although this marked the first direct military confrontation between the two nations, Iran has been waging proxy wars against Israel since 1979.
