The Tudeh Party of Iran is an Iranian communist party. Formed in 1941, with Soleiman Mirza Eskandari as its head, it had considerable influence in its early years and played an important role during Mohammad Mosaddegh's campaign to nationalize the Anglo-Persian Oil Company and his term as prime minister. Tudeh became a pro-Soviet organization after the Iran crisis of 1946 and was prepared to carry out the dictates of the Kremlin, even if it meant sacrificing Iranian political independence and sovereignty. The crackdown that followed the 1953 coup against Mosaddegh is said to have "destroyed" the party, although a remnant persisted. The party still exists but has remained much weaker as a result of its banning in Iran and mass arrests by the Islamic Republic in 1982, as well as the executions of political prisoners in 1988. Tudeh identified itself as the historical offshoot of the Communist Party of Persia.

Mohammad Mosaddegh was an Iranian politician, author, and lawyer who served as the 30th Prime Minister of Iran from 1951 to 1953, elected by the 16th Majlis. He was a member of the Iranian parliament from 1923, and served through a contentious 1952 election into the 17th Iranian Majlis, until his government was overthrown in the 1953 Iranian coup d'état aided by the intelligence agencies of the United Kingdom (MI6) and the United States (CIA), led by Kermit Roosevelt Jr. His National Front was suppressed from the 1954 election.
