The Institute was founded in 1961 by a group of scholars with Persian interests. It was particularly active in the years before 1979 in organising and financing archaeological work at sites such as Pasargadae, Siraf and Shahr-i Qumis, but from the outset it had the wider remit of the whole spectrum of Persian studies, through early Islamic to modern times, and an interest in areas outside Persia’s present geographical and political boundaries into regions influenced by Iranian culture in the wider sense, including e.g. Central Asia and Muslim India. This is reflected in the coverage of the Institute’s journal Iran (1963-). The Institute acquired permanent premises in Tehran in the 1960s, and this continues to flourish as a centre for research, although with some restrictions, e.g. in archaeological and ethnological fieldwork, since the Islamic Revolution of 1979, and there having been no resident Director since 1987.
