The Tudeh Party’s organizational strength made it one of the most significant political forces in Iran during the 1940s and early 1950s. It established a presence in labor organizations, newspapers, educational institutions, and political associations. However, its growing influence generated concern among conservative political groups, the monarchy, and Western governments, particularly the United States and Great Britain.
The political situation changed significantly following the assassination attempt against Mohammad Reza Shah at the University of Tehran in February 1949. The government used the incident as a justification for imposing emergency measures and restricting political opposition. The Tudeh Party was subsequently declared illegal, and its activities were severely suppressed. Many of its members were arrested, while others were forced underground or into exile. This development marked an important turning point in the gradual restriction of political pluralism in Iran.
Another major transformation occurred following the nationalization of the Iranian oil industry and the political crisis surrounding Prime Minister Mohammad Mosaddegh. Mosaddegh’s government sought to establish greater national control over Iran’s natural resources and reduce foreign political influence. However, the confrontation between his government and the British government, combined with growing tensions within Iran, culminated in the coup d’état of August 19, 1953.
