Why did many Western-educated Iranians leave the country after the revolution?

Following the 1979 revolution, many Western-educated Iranians left the country primarily due to the systematic suppression of Western cultural influence and the rise of political persecution under the new regime.1

After the establishment of the Islamic republic, the new leadership moved to exclude secular, nationalist, and left-wing intellectuals from positions of power. The government enforced conservative social values, including strict Islamic codes of dress and behavior, which were monitored by mosque-based revolutionary committees (komītehs) and the Islamic Revolutionary Guard Corps.1

These groups engaged in intimidation and violence against those perceived as enemies of the revolution, often exceeding the brutality of the previous regime’s security apparatus. Facing this environment of persecution, violence, and the forced abandonment of Western-oriented social norms, a large portion of the educated, secularized population emigrated to Western countries, particularly the United States.12
