Iran’s Tudeh Party is a collection of documents regarding the “People’s Party of Iran” or “Party of Masses,” Iran’s largest Communist party. The documents were collected from the Russian State Archive of Contemporary History (RGANI) and the Russian State Archive of Socio-Political History (RGASPI), as well as the Stasi Records Agency (BStU) in Germany. The records concern communist and anti-communist activities in Iran during the 1970s and 1980s, as well as Iranian activities in the German Democratic Republic (GDR) and the Soviet Union. Aside from the Tudeh Party, the documents also encompass subjects such as the Iran hostage crisis and the role of Islam in Iran.
